Acus means needle. It is an ancient Chinese system of therapy utilizing long fine needles at specific points and their stimulation by various means to induce analgesia and to cure certain diseases. The specific points are known as acupuncture points or acupoints.
 
The procedure is safe. There are no post anaesthetic complications and can be used in poor surgical risk patients. The major disadvantage is poor muscle relaxation. Acupuncture has been used to produce local anaesthesia.
 
Acupoints : Alphanumeric code system is used to recognize the acupoints universally e.g. BL, LI, SP, GB etc means meridians of the urinary bladder, large intestine, spleen, gall bladder etc. respectively.

Acute tympany, commonly referred to as bloat, is a serious digestive disorder in ruminants characterized by the rapid accumulation of gas in the rumen,, leading to ruminal distension. If untreated, this condition can cause severe discomfort, respiratory distress, and even death due to circulatory failure or suffocation. Tympany is categorized into two types: frothy bloat and free-gas bloat, each requiring distinct management approaches. Nutritional management is central to preventing and treating acute tympany. This chaper provides an indepth discussion on the causes, pathophysiology, clinical signs, and nutritional
strategies to manage and prevent acute tympany in ruminants.
Types of tympany
1. Frothy bloat: Occurs when gas produced during fermentation becomes trapped in a stable foam, preventing its release through eructation (belching). It is associated with diets high in lush legumes (e.g., alfalfa, clover) or finely ground grains.
2. Free-gas bloat: It results from physical or functional obstruction of the esophagus or impaired eructation mechanisms. Common causes include esophageal obstruction, hypocalcemia, or damage to rumen motility.

Introduction

The egg production in India is 75 billion and the broiler production is 4.2 million tonnes per annum. The growth rate of layer market is 6-7 percent per annum and broiler market is 8-10 percent per annum. The Indian poultry sector is valued at INR 1 lakh cr or USD 15.38 bn. Approx. 80 percent of egg production is contributed by commercial poultry farms, remaining comes from household/ backyard poultry. Backyard poultry plays a key role in supplementary income generation and family nutrition to the poorest of the poor. It is estimated that there are around 30 million farmers engaged in backyard poultry as per 19^th Livestock Census. Backyard poultry are being practiced for its inherent strengths. Free range birds reared by the farmers have the advantage of small body size, coloured plumage, broodiness to hatch chicks, adaptation to harsh climatic condition, lower diseases and production with least investment. The birds are scavenging in the backyard, supplemented by kitchen waste and are kept in low height houses for shelter using locally available materials. It helps to improve the nutritional status of rural poor and also improve the subsidiary income of the poor people. Such stocks make minimal use of land, labour and capital and integrate well into the backyard. Backyard poultry production system is self-sustaining because of minimal needs and can be afforded by poor people of the rural areas. The high yielding white feathered chicken varieties being reared in the intensive poultry farming are not suitable for backyard / free range backyard poultry farming due to the adverse climatic and high pathogen load prevailing in such rearing practices. Backyard poultry farming is an in-separable part of the poor tribal people and it will continue to be due to its advantages. Although backyard poultry production is not an occupation per se, it often supplements household income, primarily for poor families. Strengthening backyard poultry production may help overcome poverty and malnutrition in impoverished communities. However, the effect of climate change on these birds needs to be studied for its sustenance.

Innate immunity provides the first line of defense against invading pathogens. But if the pathogens are able to escape from the first line of defense mechanisms, the body uses, another set of immune mechanisms which provide defense in a more specialized manner. These are called second line of defense mechanisms. The second line of defense mechanisms are highly specific in nature. These are called adaptive immune response and provide adaptive immunity. It is also called acquired immunity since these immune responses are not present prior to the exposure of the microbes. When the body is exposed to foreign substances or microorganisms, body develops adaptive immune responses. Adaptive immunity is a set of specialized cells and processes that function to eliminate pathogens or prevent their growth.

Adenoviruses have been found in several species of birds and animals. There are at least 12 serotypes of chicken adenoviruses. The chicken adenoviruses are host specific, meaning they will not infect other animal species. Avian adenoviruses are divided into three major groups. Members of each type may share group antigens, but there is no common antigen shared between types.

The word administration is derived from Latin word Ad + Minister means “to care for” or look after people / to manage affairs.

Why Study Management Theory
Theories are perspectives with which people make sense of their world experiences. A theory is a coherent group of assumptions put forth to explain the relationship between two or more observable facts.
    i.    Theories provide a stable focus for understanding what we experience. A theory provides criteria for determining what is relevant.
    ii.    Theories enable us to communicate efficiently and thus move into more and more complex relationships with other people.
    iii.    Theories make it possible indeed, challenge us-to keep learning about our world.

Adoption

Adoption is a decision to make full use of an innovation as the best course of action available.

Steps in adoption process

Ryan and Gross (1943) were probably the first to recognize that the adoption of a new idea consisted of stages. They distinguished between awareness of hybrid seed cron conviction of its usefulness, trial acceptance and complete adoption of the innovation.

Adoption is essentially a decision making process. According to Johnson and Haver (1955), decision making involves the following steps.

Introduction

Rice is considered as the most important crop of India both in terms of area as well as value of output. It is estimated to contribute about 2.5 per cent of Gross Domestic Product (GDP) of India and provides employment to a large work force in crop production and in paddy processing.

According to Reinsurance Company ‘Munich Re (2001), costs associated with natural disasters has gone up 14 fold since the 1950. Every year from 1991 to 2001, an average of 211 million people in the world were killed or affected by natural disaster. Described as one of the “Worst Disasters” in recent history the Tsunami travelled 4,500 km across the Indian Ocean in a period of about seven hours causing damage to twelve countries including Sri Lanka, India and Thailand most dramatically impacted, The FAO estimates that in the countries hardest hit by the disaster (Indonesia, Sri Lanka, Maldives, India and Thailand), a total of 47,000 ha of agricultural land has been damaged (FAO, 2005).

Theworld fashioned and occupied by three fourth of the water. Fisheries activities are an indispensable part in the life and livelihood of the peoples. Aquaculture is the most important role for the upward economic strengthening and social mobility. Most of the inland fish farmers are poor due to lack of financial resource. Because of the poor production through the inland fish culture, the most of the farmers in Tamilnadu are undertaking composite fish culture technology. Demand for fish is rapidly increasing due to the growing population and awareness about the superiority of fish to other meats. The marine and freshwater sectors growth were 2.5 and 8 per cent respectively (Ayyapan and Diwan, 2004).

Introduction

Among the various vegetable crops, tomato (Lycopersicurn esculentum) is one of the important and popular vegetable and plays an important role in balanced nutrition and hence it is called as `poorman’s orange’. Tomato fruits can be seen in the market round the year. In India, tomato occupies an area of 2,90,279 ha with the productivity of 15.85 t/ha and production of 46,03,446 tonnes (www.nhb.gov.in). Among the different districts of Tamil Nadu, Salem district has an area of about 6311 hectares under tomato with 17,359 tonnes of production. Pest management is one of the important dimensions in cultivating tomato crop that needs significant attention. The objective of pest management technologies are maximize pest control in terms of overall economical, social and environmental values. In order to restore ecological balance, it is necessary to integrate all the available pest management techniques in the most compatible manner with the least use of chemicals which is the principle of pest management. ‘Pest management technology’ utilizes all suitable techniques and methods in a compatible manner as possible and maintains the pest population below their economic injury levels given by Bikramjit et al. (2007).

1. Introduction

Food is an essential requirement for survival. We work hard to earn money so that we can feed ourselves. However, at the end of the day, many of us are unsure about the quality of food we consume. The allure of money, along with a general disregard for humanity, has resulted in the addition of adulterants to food ranging from simple stones in rice to the more harmful chemicals in food of daily use. Surprisingly, food fraud is not a modern issue. There are several references to fraudulent food behaviour as early as the Romans, but it is usually considered to be the Victorian who places food fraud on the map.

Introduction

Fruits and vegetables are an important part of healthy human diet. Consumption of vegetables is widely promoted by Governmental health agencies since it provide consumers essential nutrients such as vitamins, minerals, dietary fiber and phytochemical compounds, at a relatively low calorie density. Furthermore, the consumption of vegetables has been strongly associated with reduced chronic and degenerative diseases such as cancer and heart related ailments. The United States Department of Agriculture recommends five to nine servings of fruits and vegetables daily (Berger et al 2010). In recent years, fresh-cut produce has become more popular due to their convenience, freshness, taste and assumed “Healthiness”.

In recent years dietary supplements have gained attractiveness within fitness and wellness circles. The other commonly used terms areNutraceuticals, dietary supplements or wellness-focussed foods. Being highly nutritious they are associated with a number of potential therapeutic effects. Nutrient-rich ingredients like fruits, vegetables, nuts, seeds, and grains are often considered dietary supplements as well. Oats fibre called, beta glucan, which has been shown to reduce inflammation, enhance immune function, and perk up heart health.

1. Conventional and Non-conventional Dietary Supplements

Nutrient-rich foods like fruits, vegetables, and legumes are often considered dietary supplements. Meanwhile, modified foods have been fortified with micro and macro nutrients to boost health benefits of foods.

Diagnostic imaging refers to technologies that doctors use to look inside the body of the patient for clues about any disease condition. A variety of machine and techniques can create pictures of the structures and activities inside the patient body. In India, some of these modalities like digital radiography and ultrasonography are being used at some of the veterinary colleges and reaseach institutes while at some places some of the veterinarians have access to the techniques like computed tomography (CT) and magnetic resoncace imaging (MRI) of the human hospitals. So this is the responsibility of the scientists and researchers engaged in the advancement of the diagnostic imaging and the manufacturing companies to make these facilities cot effective so that an animal of a common man can be benefited with these facilities.

Advances in technology are revolutionizing the detection of metabolic diseases in animals, making diagnostics more precise, rapid, and non-invasive. From wearable sensors and metabolomics to AI and nanotechnology, these tools are enhancing animal health and productivity. As these technologies become more accessible, they promise to transform veterinary medicine and animal husbandry, ensuring early detection, effective management, and improved outcomes for animals.
Sensor-based technologies have emerged as a game-changer in the detection and management of metabolic diseases in dairy animals. These tools provide continuous monitoring, early detection, and real-time insights, enabling better health management and increased productivity. This chapter explores the most promising sensor-based technologies used for diagnosing metabolic diseases in dairy animals, their applications, and the future of sensor-driven animal health management.
Metabolic diseases like ketosis, milk fever (hypocalcemia), acidosis, and displaced abomasum significantly impact dairy productivity and animal welfare. Early detection is critical for reducing treatment costs, improvingrecovery rates, and minimizing production losses. Traditional diagnostic methods are accurate and often invasive, time-consuming, and not feasible for large-scale monitoring. Therefore, sensor-based technologies offer a solution by enabling continuous and non-invasive monitoring of physiological and biochemical parameters.

Biomedical signals provide valuable information about physiological conditions and support continuous health monitoring. This chapter introduces ECG, EEG, EMG, PPG, respiratory and blood-pressure signals and examines the challenges associated with their acquisition and interpretation. It discusses noise removal, filtering, normalization, resampling and artifact correction before presenting time-domain, frequency-domain, time–frequency, wavelet and nonlinear feature-extraction methods. Feature selection and dimensionality reduction are considered in relation to model accuracy and clinical interpretability. The chapter also explores machine learning, deep learning and hybrid approaches through applications involving arrhythmia detection, seizure prediction and wearable cardiovascular monitoring, highlighting their importance in intelligent and personalized healthcare.

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.

Food packaging protects products from physical, chemical, biological and environmental influences while helping to maintain safety, freshness and quality. Advanced packaging systems perform functions beyond simple containment by regulating gases, moisture, temperature and microbial activity. The chapter examines modified-atmosphere, controlled-atmosphere and vacuum packaging, together with active and intelligent systems. Time-temperature indicators, freshness indicators and biosensors enable real-time monitoring of product condition. Edible and biodegradable materials provide more sustainable alternatives to conventional packaging, while nanotechnology can improve mechanical, barrier and antimicrobial performance. Shelf-life modelling and hurdle technology are also considered as tools for designing integrated packaging systems suited to specific foods and storage conditions.

Electrophoresis

The mobility of ions in an electric field is the basis for the separation method known as electrophoresis. Ions that are negatively charged move toward a positive electrode, while those that are positively charged move toward a negative electrode. Usually, one electrode is biased either positively or negatively, and the other is at the ground for safety reasons. Ions can be distinguished from one another based on their size, shape, and overall charge, which determine their migration rates.

Poly Acrylamide Gel Electrophoresis (PAGE)

Introduction

Electrophoresis is an electrochemical process in which substances with a net electric charge migrate under the influence of an electric current. This migration occurs in an agar gel or a liquid- filled buffered matrix such as cellulose acetate. Positively charged substances travel toward the cathode (negative electrode), while negatively charged substances go toward the anode (positive electrode). Different substances move at different rates depending on their charge. This movement is called electrophoretic mobility.

Proteins are charged molecules. They have a positive as well as a negative charge. Among proteins, particularly caseins, they have different contents. The charge density also varies depending on the molecular weight. Proteins have a net negative charge at a pH above 4.6, and hence they move towards the anode (positive electrode) when subjected to an electric field under alkaline conditions. Due to differences in the charge of individual protein fractions, their migration rates also differ and are hence separated into distinct bands. These bands are stained with the dye amido- black, destained with 7% acetic acid, and observed for the electrophoretic pattern.
