The process through which heat energy is transferred from a body at higher temperature to a body at lower temperature without any material medium between the two bodies is x called radiation. The outer surface of the the Sun is at higher temperature compared to the surface of the earth. Solar radiation is the electromagnetic energy emitted by the Sun. It is the primary source of energy for the Earth’s climate system, driving atmospheric and oceanic circulation, influencing weather patterns, and sustaining life through photosynthesis.2 This energy travels through space as electromagnetic waves, encompassing a broad spectrum of wavelengths, from high-energy gamma rays and X-rays to ultraviolet, visible, infrared, and radio waves. The portion of this spectrum that reaches the Earth’s surface is crucial for a multitude of processes, making thestudy of solar radiation fundamental to understanding our planet’s environment.  This introduction will lay the groundwork for exploring the characteristics, distribution, and interaction of solar radiation with the Earth’s atmosphere and surface.
5.1. Wave length of Radiation
The wavelength of radiation refers to the distance between two consecutive peaks or troughs of a wave. It’s a measure of the length of one complete cycle of the wave

Imagine the air around us. Even though we can’t see it, air has weight. Atmospheric pressure is essentially the force exerted by the weight of the air molecules above a particular point on the Earth’s surface.
Think of it like this: Imagine you’re at the bottom of a swimming pool. The water above presses you down, and you feel that pressure. Similarly, the atmosphere, a giant ocean of air, has layers of air molecules, and their weight presses down on everything below, including us.
• Atmospheric pressure is defined as the force per unit area exerted by the weight of the air column extending from the surface of the earth ,to the top of the atmosphere above that area
• It can be explain in simple terms like:
• Air has weight: Just like water or a pile of books, the air surrounding the Earth has mass, and thus, weight due to gravity.
• Weight creates pressure: This weight of the air presses down on the surface. The more air there is above a certain point, the greater the pressure.
• Like a stack: Imagine a stack of blankets. The blanket at the bottom has to support the weight of all the blankets above it, so it experiences more pressure. Similarly, the air at lower altitudes has the weight of all the air above pressing down on it.

Earth’s atmosphere is a dynamic and complex system that plays a crucial role in supporting life as we know it. This chapter explores into the fascinating world of this gaseous envelope that surrounds our planet, exploring its composition, structure, and the processes that drive both our daily weather and long-term climate. It includes:
• Composition and Structure: It will begin by examining the unique blend of gases that make up the atmosphere, including nitrogen, oxygen, argon, and trace amounts of others. It will also be explored how the atmosphere is structured into distinct layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere), each with its own characteristics and role.
• Weather: Weather refers to the short-term conditions of the atmosphere at a specific time and place. We’ll discuss the key elements of weather, such as temperature, pressure, humidity, wind, and precipitation, and how they interact to create the ever-changing weather patterns we experience.
• Climate: In contrast to weather, climate describes the long-term average of atmospheric conditions in a particular region. We’ll investigate the factors that influence climate, including latitude, altitude, proximity to oceans, and atmospheric circulation patterns. We’ll also explore the different climate zones found across the globe.
• Interconnectedness: A key focus of this chapter understands how weather and climate are interconnected. Daily weather patterns are influenced by the same fundamental atmospheric processes that shape long-term climate. For example, the way the sun’s energy interacts with the atmosphere drives both daily temperature variations and global climate patterns.

Throughout human history, people across the globe have sought to understand and predict the ever-changing skies. From the scorching deserts of North Africa to the lush rainforests of South America, and from the snow-capped Himalayas to the vast Australian outback, ancient cultures developed unique methods to forecast the weather. These traditional knowledge systems, often passed downthrough oral traditions and  storytelling, reflected the specific environmental contexts, mythological beliefs, and spiritual practices of each community. In ancient China, royal astronomers meticulously recorded weather patterns and planetary movements to guide agricultural planning and imperial decisionmakingIn Greece, philosophers like Aristotle and Theophrastus wrote extensively on weather signs and forecasting methods. In Africa, tribal communities observed animal migrations and plant behaviors to anticipate seasonal changes. Native American tribes used lunar cycles and star constellations to predict weather patterns, while ancient Indians studied the movements of planets and nakshatras (lunar mansions) to forecast monsoon rains.

Agriculture, the bedrock of human civilization, has always been intimately intertwined with the vagaries of weather. From the earliest cultivation efforts, the success or failure of harvests has been profoundly influenced by temperature, rainfall, sunlight, wind, and humidity. Agricultural meteorology, at its core, is the study of the relationship between meteorological conditions and agricultural production. It encompasses understanding how weather and climate impact plant growth, animal husbandry, pest and disease outbreaks, and overall farm management. This field seeks to apply meteorological knowledge to optimize agricultural practices, enhance productivity, and mitigate the adverse effects of weather-related risks.
While today we rely on sophisticated instruments, satellite imagery, and complex computer models to forecast and analyze weather for agriculture, our ancestors possessed an astute understanding of the natural world, honed through generations of observation. In ancient times, the acquisition of weather information for agricultural planning was a deeply empirical and often culturally embedded process.
Without thermometers, rain gauges, or barometers, early agricultural communities relied heavily on direct observation of natural phenomena. They meticulously watched the sky, noting the color and movement of clouds, the intensity and duration of rainfall, and the prevailing wind patterns. The appearance of halos around the sun or moon, the frequency of lightning, and even the behavior of animals were often interpreted as harbingers of impending weather changes.

The journey through meteorological data science has revealed a landscape of immense progress: unprecedented data volumes, sophisticated modeling capabilities, and increasingly accurate predictions. However, this progress is not without its complexities. We grapple with the inherent chaotic nature of
the atmosphere, the persistent uncertainties in our models, and the sheer computational demands of simulating Earth’s intricate systems. Beyond these scientific and technical challenges, the increasing societal reliance on meteorological data raises profound ethical questions concerning data privacy, equitable access to information, the responsible use of AI, and the potential for bias in algorithms. This chapter will delve into these multifaceted aspects. We will first examine the enduring scientific and technical challenges that continue to push the boundaries of research, from improving sub-seasonal to seasonal predictability to seamlessly integrating diverse data sources. Following this, we will confront the critical ethical considerations that arise when dealing with vast amounts of environmental data and its direct impact on human lives and livelihoods. This includes discussions on data ownership, algorithmic transparency, and the potential for exacerbating existing societal inequalities if not handled with care. Finally, we will cast our gaze forward, envisioning the future of meteorological data science. This forward-looking perspective will explore the potential for truly integrated Earth system models, the transformative impact of artificial intelligence, and the growing imperative for interdisciplinary collaboration to address the grand challenges of climate change and environmental sustainability. Ultimately, this chapter serves as a critical reflection, reminding us that while the technological advancements in meteorological data science are aweinspiring, their true value lies in their responsible and ethical application for the benefit of all. It is a call to continuous innovation, thoughtful leadership, and a commitment to leveraging the power of data for a more resilient and informed future.

13.1 Introduction
Having navigated the foundational statistical methods, advanced analytical techniques, visualization strategies, and the intricate world of Numerical Weather Prediction and Climate Data Analysis, we now arrive at a pivotal point in the chapter “Specialized Applications and Future Trends.” This chapter is dedicated to exploring how the comprehensive understanding and methodologies developed in previous chapters are being applied to address some of the most pressing environmental and societal challenges of our time. Furthermore, we will look ahead to the emerging technologies and interdisciplinary approaches that are shaping the future of atmospheric and climate science.
The atmosphere is not an isolated system; it profoundly influences, and is influenced by, human activities, energy systems, water resources, and urban environments. Therefore, the insights derived from meteorological and climate data are increasingly being tailored and integrated into highly specialized applications that directly impact public health, economic sustainability, and urban planning. This goes beyond traditional weather forecasting to provide actionable intelligence for complex, real-world problems.
In this chapter, we will delve into several key areas where atmospheric science is making critical contributions:
• Air Quality Analysis and Pollutant Measurements: We will explore how meteorological principles are applied to understand the transport, dispersion, and transformation of atmospheric pollutants. This includes the methods for measuring various pollutants and the sophisticated dispersion modeling techniques used to predict air pollution levels and their spread, crucial for public health warnings and environmental regulations.

12.1 Introduction
Having explored the dynamic realm of Numerical Weather Prediction, which focuses on forecasting the atmosphere’s state over days to weeks, we now shift our focus to a broader, longer-term perspective: Climate Data and Analysis. While weather describes the atmospheric conditions at a specific place and time, climate refers to the long-term average pattern of weather in a region, typically spanning decades or longer. Understanding and analyzing climate data is paramount for comprehending our planet’s past climate, identifying ongoing changes, and projecting future scenarios in a warming world. The study of climate is fundamentally data-driven. Unlike the instantaneous snapshots used in weather forecasting, climate analysis requires vast historical records, often extending back centuries or even millennia, to discern natural variability from human-induced changes. This data comes from a diverse array of sources, including instrumental records (thermometers, rain gauges, barometers), satellite observations, and proxy records (tree rings, ice cores, sediment layers) that provide indirect evidence of past climate conditions. The sheer volume and heterogeneous nature of this data present unique challenges and opportunities for analysis.
This chapter will delve into the essential aspects of climate data and the methodologies used to analyze it. We will begin by exploring the various types of climate data available, understanding their strengths, limitations, and how they are collected and curated. Crucially, we will examine how this data is used to characterize climate variability – the natural fluctuations within the climate system – and to detect climate trends, particularly those associated with global warming. We will introduce key climate indices that summarize large-scale atmospheric and oceanic patterns, providing simplified metrics for
understanding complex interactions.

11.1 Introduction
Having explored the sophisticated statistical methods for analyzing meteorological data and the powerful visualization techniques for interpreting it, we now turn our attention to the very engine that drives modern weather forecasting: Numerical Weather Prediction (NWP). This chapter delves into the intricate science and technology behind predicting the future state of them atmosphere using mathematical models and supercomputers. The challenge of weather forecasting is immense. The Earth’s atmosphere is a chaotic, non-linear fluid system, constantly in motion, with interactions occurring across vast scales, from global circulation patterns to microscopic cloud droplets. For centuries, weather prediction relied heavily on empirical rules, human experience, and the interpretation of synoptic charts. While these methods achieved some success, they were inherently limited in their ability to accurately forecast beyond a day or two, especially for complex or rapidly evolving phenomena.
The visionary idea of predicting weather mathematically was first conceived by Lewis Fry Richardson in the early 20th century. He envisioned solving the fundamental equations governing atmospheric behavior using numerical methods. However, the sheer volume of calculations required made his manual attempts impractical, famously taking him weeks to produce a 6-hour forecast that had already passed. It was only with the advent of the electronic computer in the mid-20th century that Richardson’s dream began to materialize, marking the birth of modern NWP (Fig. 11.1).

10.1 Introduction
Having explored the advanced analytical techniques that allow us to extract meaningful insights and build predictive models from meteorological data, we now arrive at a crucial stage in the scientific process: communication and understanding. The chapter, “Visualization of Meteorological Data,” focuses on the art and science of transforming complex numerical datasets into insightful visual representations. In a field as inherently spatial and temporal as meteorology, effective visualization is not just about making pretty pictures;it is a fundamental tool for exploration, analysis, and the clear conveyance  of information about atmospheric phenomena (Fig. 10.1).
Consider the sheer volume and multifaceted nature of meteorological data. We grapple with variables spanning three spatial dimensions (and often more when considering altitude), evolving dynamically over time, and encompassing a wide array of physical quantities – temperature, pressure, wind vectors, humidity, precipitation rates, radiation fluxes, and more. Raw numbers and statistical summaries, while essential for quantitative analysis, often fail to reveal the intricate spatial patterns, temporal evolutions, and interrelationships that characterize weather and climate. This is where visualization steps in,
acting as a bridge between the abstract world of numerical data and our intuitive human capacity for visual pattern recognition.

9.1 Introduction
Building upon our foundational understanding of statistical methods in meteorology, Chapter 9, “Advanced Analytic Techniques,” propels us into the forefront of data science applications within the atmospheric sciences. The imperative for these advanced methodologies stems directly from the evolving nature of meteorological data itself. Modern observations, numerical weather prediction (NWP) model outputs, and climate simulations generate an unprecedented volume of information, often arriving with incredible velocity and exhibiting immense variety in format and structure. Traditional statistical approaches, while robust for many tasks, often struggle to efficiently process such vast, high-dimensional datasets, or to fully capture the intricate, often non-linear, relationships inherent in atmospheric processes.
This chapter is dedicated to exploring why and how these sophisticated techniques are not merely supplementary, but increasingly essential. We will delve into how machine learning and deep learning algorithms excel at identifying subtle, complex patterns within massive datasets, enabling breakthroughs in areas like severe weather detection, nowcasting, and the bias correction of model outputs. We will also examine advanced spatial statistics, which provide powerful frameworks for explicitly modeling the intricate geographical dependencies of meteorological variables, crucial for accurate interpolation, downscaling, and understanding regional climate impacts. Furthermore, the chapter will introduce functional data analysis, a method particularly adept at treating continuous meteorological fields (like temperature profiles or pressure maps) as functions, allowing for a more holistic analysis of their evolution and variability. By embracing these advanced analytical techniques, meteorologists and climate scientists can unlock deeper insights, enhance predictive skill, more rigorously quantify uncertainties, and ultimately contribute to a more resilient society in the face of a changing climate. Prepare to expand your analytical toolkit and discover new frontiers in meteorological understanding.

8.1 Introduction
Having explored the intricate processes of meteorological data collection, storage, and the crucial steps of quality control and preprocessing, we nowturn our attention to how this vast and meticulously  prepared information is actually analyzed and interpreted. This brings us to the realm of statistical methods, which are indispensable tools for making sense of the inherent variability, uncertainty, and sheer volume of meteorological data. Meteorological phenomena are complex, influenced by numerous interacting factors, and often exhibit chaotic behavior. Statistical methods provide the rigorous framework necessary to quantify these complexities, identify underlying patterns, assess relationships between different atmospheric variables, and ultimately, draw robust conclusions. From summarizing observed climate patterns to evaluating forecast accuracy, and from detecting long-term trends to predicting future weather events, statistics permeate nearly every aspect of modern meteorology.
This chapter will introduce the fundamental statistical concepts and techniques applied in meteorological analysis. We will begin with descriptive statistics to summarize and visualize data, then move to inferential statistics to draw conclusions about atmospheric processes from samples. We will delve into methods for understanding relationships, such as correlation and regression analysis, and explore techniques for analyzing time series data to identify trends and periodicities. Furthermore, we will touch upon spatial statistics for gridded data and the growing role of machine learning approaches. By mastering these statistical tools, meteorologists can transform raw data into meaningful insights, enhance predictive capabilities, and advance our scientific understanding of the Earth’s atmosphere.

7.1 Introduction
The preceding chapters have detailed the myriad ways in which meteorological data is collected, from direct in situ observations to various ground-based and space-borne remote sensing platforms. We have also explored the crucial aspects of data formatting, storage, and retrieval, recognizing the immense volume and diversity of atmospheric information. However, the journey from raw measurement to actionable insight is not complete without a critical intermediate step: data quality control (QC) and preprocessing. No observational system, regardless of its sophistication, is entirely free from errors, biases, or inconsistencies. Sensors can drift, communication links can suffer interference, environmental factors can contaminate readings, and automated systems can malfunction. Consequently, raw meteorological data often contains spurious values, missing records, or systematic biases that, if left unaddressed, can severely compromise the accuracy of weather forecasts, the reliability of climate analyses, and the validity of scientific research.
This chapter will delve into the essential processes of quality control, which involves rigorously identifying, flagging, and, where appropriate, correcting or removing erroneous data points. We will explore various automated and manual techniques employed to ensure the integrity and reliability of meteorological observations. Furthermore, we will examine preprocessing steps, which prepare the quality-controlled data for its intended use, including tasks such as unit conversions, interpolation to common grids, and handling of missing values. By understanding the meticulous procedures involved in data
quality control and preprocessing, we gain a profound appreciation for how raw atmospheric signals are transformed into the trustworthy information that underpins all of modern meteorology.

6.1 Introduction
Our journey through remote sensing has, thus far, focused on the remarkable capabilities of various platforms and sensors to observe Earth’s atmosphere and surface. From the localized, high-resolution insights provided by groundbased instruments like Wind Profilers and SODARs, to the expansive, global coverage offered by an array of satellite-borne imagers, sounders, radars, and lidars, we’ve seen how a continuous stream of invaluable meteorological data is acquired.
However, the mere act of collecting this data, no matter how sophisticated the technology or comprehensive the observations, represents only the initial phase of its lifecycle. The true power and utility of remote sensing data are unlocked only when it can be efficiently organized, securely preserved, and readily available to the diverse community of meteorologists, climate scientists, researchers, and operational forecasters who rely on it daily. This necessitates a profound understanding of the principles and practices governing data formats, data storage, and data access.
The sheer volume, velocity, and variety of remote sensing data pose significant challenges. Petabytes of information are generated annually, requiring robust infrastructure and standardized methodologies to ensure its integrity, interoperability, and long-term usability. Without effective strategies for managing this deluge of information, the potential of remote sensing to enhance weather prediction, advance climate science, and inform critical decision-making would remain largely untapped. 

5.1 Introduction
The Earth’s atmosphere is a vast, dynamic, and interconnected system, constantly in motion and influencing every aspect of our lives. Accurately observing and understanding this complex system is fundamental to predicting weather, monitoring climate change, and responding to environmental challenges. While ground-based platforms provide invaluable high-resolutiondata at specific locations, theitr  spatial coverage is inherently limited. This is where satellite remote sensing emerges as a revolutionary tool in meteorology. By observing the Earth and its atmosphere from space, satellites offer an unparalleled vantage point, providing global and continuous coverage that is impossible to achieve with ground-based instruments alone. They can capture data from remote oceans, deserts, and polar regions, offering a truly holistic view of atmospheric processes.
Satellite remote sensing enables meteorologists to measure a wide array of atmospheric parameters, including temperature and humidity profiles, cloud properties (type, height, movement), wind fields, precipitation rates, and the distribution of atmospheric gases and aerosols. This wealth of data is crucial for initializing and validating numerical weather prediction models, tracking severe storms, monitoring long-term climate trends, and conducting fundamental atmospheric research. This chapter will delve into the fascinating world of satellite remote sensing in meteorology, exploring the principles behind how these orbiting observatories collect data, the various types of meteorological satellites and their specialized instruments, and the diverse applications of the information they provide for understanding and forecasting
our planet’s weather and climate.

4.1 Introduction
Having explored the direct, “hands-on” approach of in situ observations in the previous chapter, we now turn our attention to remote sensing. In contrast to in situ methods, remote sensing allows us to gather information about the atmosphere without physically touching it. Instead, it relies on the detection of electromagnetic radiation (or acoustic waves) that has been emitted, reflected, or scattered by the atmosphere or its constituents.
This chapter will focus specifically on ground-based remote sensing platforms. Positioned on or near the Earth’s surface, these instruments offer unique advantages for continuous monitoring of the atmosphere above a fixed location, providing valuable insights into vertical profiles, temporal evolution, and localized phenomena. From radars that peer into storms to lidars that probe aerosols and winds, and radiometers that measure emitted radiation, ground-based remote sensing provides a vital link between highly localized in situ measurements and the broader spatial coverage offered by satellite and
airborne systems.
We will delve into the fundamental principles behind several key groundbased remote sensing instruments used in meteorology. This will include an examination of how they interact with the atmosphere, the types of atmospheric parameters they can measure (such as precipitation, wind, temperature, humidity, aerosols, and trace gases), and the strengths and limitations of each technique. By understanding the capabilities of these ground-based “eyes” on the sky, we can better appreciate their contribution to weather forecasting, atmospheric research, and environmental monitoring.

3.1 Introduction
Understanding the Earth’s atmosphere—its intricate dynamics, ever-changing weather patterns, and long-term climate trends—hinges critically on the quality and detail of the observations we collect. While remote sensing technologies offer broad perspectives from a distance, a fundamental and indispensable category of atmospheric data comes from in situ observations. The term “in situ,” meaning “in place” or “on-site,” precisely describes the nature of these measurements: they are direct, physical readings taken within the atmospheric volume itself.
These direct observations are the bedrock of meteorological science. They provide the ground truth for atmospheric conditions, offering unparalleled precision in measuring parameters such as temperature, humidity, atmospheric pressure, wind speed and direction, and the characteristics of precipitation. Unlike indirect sensing, in situ methods involve instruments physically interacting with the air, yielding highly accurate and localized data points. This granular detail is crucial for a multitude of applications: it allows for the precise calibration of remote sensing instruments, provides essential validation for complex numerical weather prediction models, and enables scientists to dissect and understand fine-scale atmospheric processes that influence local weather.

2.1 Introduction
Building upon the foundational understanding of meteorology and data science established in Chapter 1, we now turn our focus to the fundamental physical processes that govern our atmosphere and the essential principles behind how we measure them. The Earth’s atmosphere is a dynamic fluid system, and its behavior is dictated by a complex interplay of physical laws. To truly comprehend weather phenomena, from the smallest updraft to the largest global circulation patterns, one must grasp the underlying atmospheric physics. This includes understanding how energy is transferred, how gases and
water vapor behave, and how forces shape atmospheric motion.
This chapter will delve into these core physical concepts, providing the theoretical bedrock necessary for a deeper appreciation of meteorological processes. Furthermore, accurate and reliable data is the lifeblood of modern meteorology and, by extension, data science applications within the field. Therefore, we will also explore the fundamental principles that underpin the measurement of key atmospheric variables.

1.1 Introduction
Meteorology, at its heart, is the scientific endeavor dedicated to understanding the Earth’s atmosphere and the myriad phenomena that occur within it. More than just the art of predicting whether it will rain tomorrow, meteorology is a robust interdisciplinary science. It intricately weaves together principles from physics, chemistry, and mathematics to unravel the complexities of atmospheric processes. From the gentle caress of a breeze to the formidable power of a hurricane, meteorology seeks to explain the underlying mechanisms that drive our ever-changing weather and long-term climate patterns.
The study of meteorology encompasses a wide array of atmospheric characteristics. Meteorologists delve into the composition of the atmosphere, examining the various gases and tiny particles known as aerosols that reside within it. They also investigate its vertical structure, distinguishing between layers like the troposphere, where most weather occurs, and the stratosphere, home to the ozone layer. The motion of the atmosphere, manifested as wind systems ranging from local gusts to global circulations, is a central focus. Furthermore, meteorology explores the thermodynamics of the atmosphere, including how heat is transferred and how temperature changes, as well as the role of water in the atmosphere, from humidity to the formation of clouds and precipitation – the realm of atmospheric hydrology. Even the captivating
optical phenomena we sometimes witness, such as rainbows and halos, fall under the purview of meteorological inquiry.

Components of Project Finance
1. Capital Structure Determination: Deciding on the mix of debt, equity, and other sources of financing that will be used to fund the project. The goal is to structure the capital in a way that minimizes costs, maximizes returns, and balances risk. Here’s an elaborate breakdown of the steps involved in capital structure determination:

Introduction

As India is the leading global economy with livestock contributing 4.66% in total GVA to Indian Economy (PIB, 2024) and ranks 1st in Milk Production, 2nd in Egg production, 5th in meat production (BAHS, 2024). Being the largest exporter of milk and meat in the world , this has led to the intensification of animal production due to the increasing demand of major livestock products (MLPs), which has led to an increasing overall use of antimicrobials. Antimicrobials are invariably used to preserve animal and public health, but also as growth promoters at a sub-therapeutic level. The overuse and misuse of antibiotics can contribute to antimicrobial resistance. The growing resistance to antimicrobial drugs could reverse the therapeutic benefits; animals’ resistance to antimicrobial drugs, reduces productivity and leads to economic losses. Unwanted antimicrobials residues may be present in products of animal origins, in animal waste contaminating soil and water and the environment. Seventy-five to ninety percent of antimicrobials used in livestock are excreted, mostly unmetabolized. AMR poses a serious threat to the safety and quality of animal origin food, food security and livelihoods. Unhealthy and unproductive animals are no longer able to generate food products of acceptable safety and quality for human consumption and can no longer contribute to income generation. Insufficient standards for residues in animal food products, reduces the livestock sectors potential of access to trade and increases public health risks (https://www.fao.org/antimicrobial-resistance/key-sectors/animal-production/ en/).

Introduction

Wound is a disruption to the epithelial integrity of the skin, extended in-depth to subcutaneous tissue and other body parts such as ligaments, muscles, blood vessels, nerves, and bone (Robson et al. 2001). An appropriate wound healing is essential for the restoration of disrupted anatomical continuity (Begum, 2000). We have observed increasing interest in research based on traditional medicines of the world in the recent era (Medina-Franco et al. 2013). Traditional and complementary medicine regains popularity not only in developing countries but also in developed countries. Common and known practices across the globe of traditional medicines include Herbal, Ayurveda, Siddha, Unani, Iranian, Islamic, Vietnamese, Chinese, Acupuncture, African and other pseudo-medical knowledge (Dorai 2012). According to World Health Organization (WHO), traditional medicine ‘the health practices, approaches, knowledge and beliefs incorporating plant, animal and mineral-based medicines, spiritual therapies, manual techniques and exercises, applied singularly or in combination to treat, diagnose and prevent illnesses or maintain well-being’. Saxena et al. (2013) reported that phytochemicals present in plants are liable for preventing disease and promoting health. Antibiotics used in the treatment of wound infections are now proved to have adverse effects in the human body and in pathogens where resistance is emerging. Attention has, therefore, turned towards extracting biologically active compounds from plant species having wound healing property (Pattanayak and Sunita, 2008).

Introduction

Canine epilepsy, a prevalent neurological disorder, significantly impacts the quality of life for both dogs and their owners. Traditional anticonvulsant therapies often yield inconsistent outcomes, necessitating the exploration of alternative treatments such as homeopathy [1][2]. Homeopathy’s individualized approach aligns with the principles of unicism, focusing on holistic care tailored to each patient’s unique symptom profile [3]. However, the subjective nature of remedy selection and response assessment poses challenges for practitioners.

The integration of Artificial Intelligence (AI) and Machine Learning (ML) offers a promising avenue to address these challenges [4]. Predictive models can analyze complex datasets to uncover patterns that guide remedy selection and treatment strategies. This study evaluates the comparative performance of Logistic Regression, Random Forest, and XGBoost in predicting treatment outcomes for canine epilepsy managed with homeopathic remedies.

Introduction

Avian medicine is a rapidly growing field, with an increasing number of exotic bird species being kept as pets. However, the unique anatomy, physiology, and behaviour of these birds present several challenges as well as new opportunities for veterinarians and researchers.Now a day’s birds are gaining popularity over dogs and cats because of various reasons listed below:

a. They are more suited in present life style as can be suited well in small spaces.

b. They require low maintenance with relative low cost of maintenance and live longer life.

c. They form very strong bonds with their owners.

Birds can be classified into different families, such as Psittaciformes, Passeriformes, Columbiformes, Piciformes, Anseriformes, Galliformes etc. containing numerous species (>10,000). The first documentation of parrot as a pet was found in Rig Veda, written more than 3000 years ago. Evidence of bird keeping is observed in ancient civilizations of Greece, Rome, China and Egypt. In Greek mythology, Raven (a crow) was mentioned as a symbol of good luck and was associated with God Apollo (God of prophecy). Crows are also considered as ancestors in Hindu mythology and food (pinda) is offered to crows during ritual of paying homage to dead persons. In most of the countries psittacine and passerine birds are preferred as pet birds.

Introduction

Mithun (Bos frontalis), or ‘Gayal’ or ‘Eso’ or ‘Sial’ or ‘Sandong’ or ‘Wei’, is a rare bovine species, exclusively found in the northeastern hill region (NEHR) of India at an altitude of 300-3000 m. It plays an important role in the socio-economic and cultural life of indigenous tribes of Arunachal Pradesh, Nagaland, Mizoram and Manipur and is aptly referred to as the ‘Pride of Northeast India’ (Mukherjee et al. 2019). Besides India, mithun population is distributed to China, Bangladesh, Thailand, Bhutan, Myanmar, and Malaysia. The Indian mithun is a medium- to large-sized majestic ruminant with a characteristic jet-black body, an ash-colored forehead, and ‘white stockings’ on all the limbs. This unique animal has a special preference for salt feeding, is a skilled browser even in steep, hilly terrain, and does not need pasture land like cattle. Mithun is primarily reared under a free range system as an important source of lean meat, rich in amino acids, proteins, PUFA, etc. On September 1, 2023, the Food Safety and Standards Authority of India (FSSAI) officially certified the mithun as a food animal (Joshi et al., 2021; Lalchamliani et al., 2024; Ramesh et al., 2024). Compared to milk from other species, mithun milk has much larger quantities of fat, lactose, solids-not fat (SNF), calcium, important vitamins A, D, and E, essential amino acids, and polyunsaturated fatty acids (Devi et al., 2023).

Introduction

A complete neurological examination is warranted whenever an equine patient displays signs consistent with neurological disorder or to establish that the horse is neurologically normal (e.g., pre-purchase examination). Neurological examination of equine patient is challenging due to their large size, which prevents veterinarian from using many of the tests used for small animals. The key to a successful neurologic examination is to do the examination in a consistent and organized fashion. It is important to develop a routine, then do it the same way each time. This approach ensures that some parts of the examination are not forgotten and it also increases the consistency of the exam as you examine more number of equine patients. A standardized examination form is a valuable aid in this and can be concise. The goals of the neurologic examination are to determine whether disease of the nervous system exists, to localize the lesion to a particular area of the nervous system, and to describe and record the responses as a baseline for future evaluations. In this paper, a complete neurological examination is described with special emphasis on field conditions.

Asiatic Elephant (Elephas maximus) is the national heritage animal of India. This particular species now exists in 13 Asian countries including India. As per 2017 census, India is home to an estimated figure of 29,964 elephants that is >60% wild population of the globe. Once distributed across the country, now they are squeezed to 14 states grouped in four regions ie., southern (14,612), north-eastern (10,139), east-central (3,128) and northern regions (2,085). There are 2675 captive elephants across different states under both private and government custody. This largest terrestrial mammal is protected under Seclude I species of Indian Wild Life Protection Act, 1972.

Both central and state Government are implementing short- and long-term programmes for health and well-being of captive as well as free-range elephants. The Central Government has established an ‘Elephant Cell’ at the Wildlife Institute of India (WII), Dehradun to provide technical inputs to the ministry for strengthening the efforts towards conservation of elephants. Add-on, the ‘Project Elephant’ was launched in 1991-92 in the Ministry of Environment, Forests and Climate Change to restore the elephant habitats and reduce their sufferings. Elephant habitats are notified as Elephant Reserves that are basic management units for elephant conservation and managements. A total of 33 Elephant Reserves has been notified in the country. A book titled, ‘Caring for elephants: Managing health and welfare in captivity’ is edited for field officers, veterinary professionals and elephant handlers.

Learning objectives

1. Recognise inflammatory cell types

2. Recognise common skin pathogens

3. Diagnostic test are best for each case

4. Gain experience in interpretation

5. Recognise important artefacts

″The most crucial step towards healing is having the right diagnosis″. While approaching a case, a clinician should follow appropriate steps in a systematic way for accurate diagnosis of dermatological disorders. A careful history is a first step to choose appropriate diagnostic tests.

Introduction

Canine atopic dermatitis (CAD) is a chronic inflammatory skin disease marked by itching (pruritus), redness (erythema), and recurrent infections. While traditionally considered an immune-mediated condition, recent studies highlight the significant role of skin barrier dysfunction in its development. A key aspect of CAD is the compromised skin barrier, which increases permeability to allergens, irritants, and microorganisms, thereby worsening the disease. The skin barrier is a complex, dynamic structure essential for protecting dogs from environmental challenges. The stratum corneum—the outermost layer of the epidermis—serves as a crucial defense against environmental insults, allergens, and pathogens. In dogs with atopic dermatitis, this barrier often becomes impaired, leading to increased transepidermal water loss (TEWL), greater allergen penetration, and secondary infections. This dysfunction both results from and contributes to the condition, creating a self-perpetuating cycle of barrier disruption, inflammation, and immune dysregulation.

As the heart diseases in companion animals is becoming common as in humans, the research in canine cardiac diseases is one of the most extensive studies in the present scenario. As per the available literature, the overall occurrence of various cardiac abnormalities ranges from 0.37 percent to 1.67 percent in various parts of the country. Whereas, in western parts of the globe, nearly 8 million dogs suffer from heart disease accounting 10% of all dogs in the United States. Heart diseases are common among older dogs; up to 75% of senior dogs have some type of heart condition, and unfortunately, most go undiagnosed due to varied reasons. The recognition of canine cardiac diseases has been delayed, and ignored on account of lack of awareness and knowledge by the owner and inadequate diagnostic facility in our country. Physical examination, radiography, electrocardiography and echocardiography are most useful diagnostic procedures employed in diagnosing the cardiac diseases in dogs. However, majority of the acquired cardiac diseases are being managed medically with one or a combination of drugs. Improved diet management and health care of companion animals have led to increased life expectancy, as a result, cardiac diseases have become pivotal causes of death for both dogs and cats. For such reason, a major objective has become to increase the quality of life by reducing the expansion of cardiac diseases via early detection of diseases and provision of effective treatment.

Renal failure is one of the most commonly presented conditions in veterinary clinics world over. Although the potential for recovery is favorable, most animals die due to multisystemic effects induced by azotemia. Hence, extracorporeal removal of endogenous and exogenous toxins is very essential for expanding the window of recovery. Hemodialysis has been used in treatment of veterinary patients for the last 50 years and is still one of the most expensive and technically demanding treatment modalities in veterinary medicine. It is an advanced extracorporeal renal replacement therapy which has recently transitioned from a clinical curiosity to a more advanced standard for management of acute kidney injury (AKI) and chronic kidney disease (CKD) in companion animals particularly dogs and cats.

In addition to eliminating selective toxins that cause AKI, regardless of renal function, hemodialysis is also effective in the removal of pharmacokinetically active soluble uremic substances in CKD to enhance life expectancy and quality of life (Singh, 2021). Other common indications of hemodialysis in veterinary medicine include fluid overload, dysregulated body fluid composition, drug overdose or intoxications (Foster, 2020; Singh et al?, 2024). Medical management alone is often insufficient to control the clinical signs and metabolic abnormalities associated with uremia when AKI is severe or when there is involvement of acute on chronic kidney disease. Consequently, animals are at risk of death within a short therapeutic window, despite the potential reversibility of AKI and the improvement of life expectancy in CKD.

Introduction

One of the remarkable advancements in veterinary medicine recently is the application of interventional cardiology techniques to treat various congenital heart diseases. In dogs and cats, congenital heart diseases can be treated much more easily and with fewer complications using minimally invasive interventional approaches, rather than through traditional open-heart surgery. Among congenital heart diseases, treatment options are available for conditions such as PDA (Patent Ductus Arteriosus), AS (Aortic Stenosis), PS (Pulmonic Stenosis), VSD (Ventricular Septal Defect), ASD (Atrial Septal Defect), extrahepatic shunt, and stem cell applications. These diseases often cannot be significantly improved by medical treatment alone, making the use of the aforementioned interventional techniques essential for effective management.

Precision medicine and personalised treatment of systemic or tumour diseases gain their acceptance and application in veterinary care, too. The application of personalised medical protocols and companion diagnostics is easier and ethically well reasoned within the veterinary medical field – and it can offer many advantageous lessons to human clinical transformation, too [1]. In vitro companion diagnostics for testing the applicability and sensitivity levels of certain kinase inhibitor and immunotherapeutic drugs offer a greatly increased efficiency for veterinary cancer patients, too. As the understanding of cancer biology has advanced, the field of veterinary oncology has grown significantly, paralleling developments in human oncology. Precision medicine is an innovative approach to disease treatment and prevention that considers individual variability in genes, environment, and lifestyle. In the context of veterinary medicine, precision medicine aims to provide tailored therapies that are specifically designed for the unique genetic and molecular profile of each animal’s cancer. This approach moves away from the traditional “one-size-fits-all” model, instead focusing on targeted treatments that maximize efficacy while minimizing side effects. Companion diagnostics, such as molecular tests, help determine whether a dog or cat is likely to respond to a particular drug. For dogs and cats, precision medicine holds great promise in improving outcomes for cancers, which are among the leading causes of death in companion animals.

Tissue Doppler Imaging

Doppler echocardiography relies on detection of the shift in frequency of ultrasound signals reflected from moving objects. With this principle, conventional Doppler techniques assess the velocity of blood flow by measuring high-frequency, low amplitude signals from small, fast-moving blood cells. In TDI, the same Doppler principles are used to quantify the higher-amplitude, lower-velocity signals of myocardial tissue motion.

There are important limitations to TD interrogation. As with all Doppler techniques, TDI measures only the vector of motion that is parallel to the direction of the ultrasound beam. In addition, TDI measures absolute tissue velocity and is unable to discriminate passive motion (related to translation or tethering) from active motion (fiber shortening or lengthening). The emerging technology of Doppler strain imaging provides a means to differentiate true contractility from passive myocardial motion by looking at relative changes in tissue velocity.

Cardiomyopathies in acts can be classified broadly as Hypertrophic cardiomyopathy and non-hypertrophic cardiomyopathies. Usually, no alarming clinical signs are detected during routine examination in the preclinical stage except cardiac murmurs in some cats with HCM. This is because, that the cats are sedentary and excellent in hiding the signs of illness from the pet parents. Hence the onset is often acute with the sudden appearance of the clinical signs linked to congestive heart failure like severe dyspnoea, cardiogenic shock, aortic thromboembolism, arrhythmias and even syncope and death

Cats with CHF will be presented with severe dyspnoea, due to fulminant pulmonary oedema and or pleural effusion. The pleural effusion associated with CHF is usually a modified transudate, some cases it may be chylous .In echocardiography ,the size of the left atrium should be determined .If the LA size is normal ,then the dyspnoea may not be of cardiac origin .The presence of B-lines in the lung area in association with LA enlargement confirms cardiogenic pulmonary oedema. Stress, anaesthesia, I/V fluids and steroids leads to decompensation and fulminant pulmonary oedema. Thoracocentesis is will be helpful if there is dyspnoea due to significant pleural effusion. At least 300ml of effusion can be usually removed. The dyspnoeic cat is very fragile and should be handled carefully. Butorphanol may be given for anxiolytic effect. Oxygen administration is beneficial. Furosemide when given intravenously has an initial venodilator effect and should be repeated as required monitoring the sleeping respiratory rate (SRR). Addition of nitro-glycerine (vasodilator) reduces preload, decreases left atrial pressure and help in reducing pulmonary oedema. If the clinical signs are suggestive of cardiogenic shock or myocardial failure, Pimobendan I/V or Dobutamine CRI should be considered.

Cytauxzoonosis is an emerging tick-borne disease of domestic cats and wild felids caused by the protozoa of the genus Cytauxzoon. The common clinical findings in affected cats are similar to other hemoparasitic infections namely anorexia, depression, anemia, vomiting, icterus, and high fever. The first reporting of feline cytauxzoonosis with four fatal cases was done by Wagner in Missouri, USA in the year 1976.

Bobcats (Lynx rufus) are recognized as the natural wild reservoir of Cytauxzoon felis with prevalence reaching up to 100% in some enzootic areas (Zieman et al., 2017). This infection is highly fatal in domestic cats with 97% mortality without treatment (Meinkoth and Kocan, 2005). However, subclinical infection in some cats has also been evidenced i.e., they were infected with C? felis but did not display the acute clinical signs of the disease before diagnosis (Brown et al., 2010 and Rizzi et al., 2015).

Several other wild felids apart from bobcats and domestic cats have been found to be affected by fatal or nonfatal Cytauxzoon sp. infection. These include lions, jaguar, cougars, pumas, ocelots, Iberian lynx, meerkats, European wild cats and Asiatic wild cat, panthers, and tigers (Jakob and Wesemeier, 1996; Rotstein et al., 1999; Yabsley et al., 2006; Andre et al., 2009; Filoni et al., 2012 and Furtado et al., 2017).

The Central Nervous System not only consists of the Brain but also involves the Spinal cord.

The spinal cord is responsible for conveying information from the Brain to the rest of the body via the peripheral nervous system. The spinal cord can be divided into 4 functional segments.

1. C1-C5 (Upper Cervical Segments)

2. C6-T2 (Brachial Plexus)

3. T3-L3 (Thoraco - Lumbar)

4. L4-S3 (Lumbo-Sacral Plexus )

It is important to note that the motor and sensory function of the pelvic limbs are not only controlled by the Lumbo-Sacral plexus but also involve the Thoraco Lumbar segments (T3-L3) of the spinal cord. It is important to understand not only the neuroanatomy, but also the functional anatomy before approaching a neurological patient.

AMR is undoubtedly the most serious challenge ever faced by the world health community because of its multifaceted complex nature and its overwhelming impact over the human and veterinary communities. Livestock sector is no exception to have the serious and devastating impact from the emergence and spread of AMR. Because of a steady shift towards intensive farming and increased stocking density there has been increase occurrence of infectious diseases. Growing world population, rapid urbanization, and deforestation, shrinkage of grazing land all aided to this process. This leads to increased usage of antimicrobials in food animals – cause of concern for the scientific community as AMU is known the single most important driver of AMR.

Punjab, known as the “breadbasket of India,” relies heavily on livestock, particularly cattle and buffalo, for its agricultural prosperity. These animals play a crucial role in the region’s dairy industry, contributing significantly to milk production and rural livelihoods. However, like all livestock, cattle and buffalo in Punjab are susceptible to a range of diseases that can impact their health, productivity, and overall well-being. Timely and accurate diagnosis is essential for effective treatment and prevention. This article explores some of the most common diseases affecting cattle and buffalo in Punjab, along with the diagnostic procedures used to detect and manage these health issues, ensuring the sustainability and growth of the dairy sector.

Hydatidosis

Hydatidosis is a zoonotic disease caused by metacestode stages of parasite Echinococcus granulosus and is recognized as a major public health problem worldwide. This tapeworm is found in small intestine of the canid (definitive host) where it produce proglottids containing eggs. Upon shedding through faeces the later are ingested by the cattle, buffaloes and other intermediate hosts including man. These hatch in their intestine and the oncosphere invade circulatory system and lodge in various organs (liver, lung, brain etc.) where they develop into large thick walled unilocular cavity called hydatid cyst, which expands and can reach very large size and buds hundreds and thousands of protoscoleces endogenously. In a survey on hydatid cysts, a prevalence rate of around 5% has been recorded in more than 4000 meat samples of different animals in Punjab.

Introduction

Climate change, a global phenomenon of present time, has emerged as the greatest challenge of the world in the twenty-first century. Rising earth’s surface temperature is one of the most threatening factors coming into view. The substantial changes in the earth’s climate have an impact on ecosystems, economics and societies in a variety of ways (Sharma et al., 2024). It is one of the important environmental, agricultural, human and animal health issue. Climate change is an association of multidimensional effects involving physical characteristics, causes and consequences (Visschers, 2018). The climate change has resulted in to increasing global average temperature of air and ocean, melting of snow, rising of ocean level, change in the rainfall pattern and extreme whether events such as drought, flood, heat waves, storms etc.

Being polytocous animal, sow give birth several (8-14) piglets in each farrowing, mother pig find several deficiencies and disorders during gestation, farrowing and postnatal conditions. Prior to birth intrauterine competition amongst the feotus piglets for nutrition and gas exchange is a big stress for abortion. Several infectious and non-infectious causes may hamper proper growth and pathological conditions resulting mortality (15-20%) in piglets than weaner and adults (Sarma, et al, 2012). Several risk factors are also responsible for piglet mortality.

Prenatal factors: Insults during pregnancy can impact a piglet’s ability to survive after birth and regulate their body temperature. Some maternal aspects that affect survability and mortality amongst piglets are prolong farrowing duration more than 4 hours, number of parity of sow, usually first and second parity show high mortality than subsequent parities and also older sow lose more piglets.
