Introduction

Global warming is chiefly due to combustion of fossil fuels for multifarious energy needs, causing emission of greenhouse gases which trap energy from the sun leading to warming. These climate changes bring in variation in patterns and emergence of new zoonotic diseases to newer areas. These changes sometimes create conducive conditions for the propagation of insect vectors. History shows that most of the diseases have a direct correlation with climatic changes. The survival and propagation of pathogens are directly related to temperature and humidity etc. Extreme shifts in weather patterns resulting from global warming and climate changes adversely affect the ecosystem resulting in new diseases, re-emergence of earlier diseases including emergence of zoonotic diseases. The emergence of the new cholera strain O: 139 and outbreaks of Dengue, West Nile virus and Rift Valley fever in newer and non-endemic areas have been linked with the El Nino effect. The spread of disease agents may be facilitated by factors including environmental conditions, the presence and availability of suitable hosts, the arthropod's feeding behavior and host preferences.

The term Anesthesia means loss of sensation.

GENERAL ANESTHESIA

In the technique of anesthesia, a drug is capable of causing loss of sensation together with loss of consciousness, sufficient to allow a surgical operation to be carried out.

Routes of General Anesthesia (G.A.)
Inhalation

Ether, Nitrous oxide, Halothane, Chloroform etc.

Sampling of Milk for Analysis

A careful and accurate sampling is of utmost importance for the analysis of milk. It is a fundamental principle of sampling that the quantities withdrawn, must be proportional to the quantities contained in the respective containers and uniform throughout in its composition.Thorough mixing of milk must first be ensured either by stirring or by shaking gently. If milk from an individual animal is to be sampled, the sample should be taken from the middle of vessel containing the whole amount of milk. If the sample bottles have been standing for sometime, resulting in the separation of fat in the cream layer or lumps of fat appear, the bottles may be heated in a water bath upto 40°C to melt the fat before mixing. Milk should not be shaken very violently under any circumstance as it may result in an uneven distribution of fat.

Analyzing feeds for nutrient content is essential for proper balancing of livestock rations. This is especially essential for those feeds that have undergone the fermentation process. Silage samples should be analysed for dry matter, protein fractions (degradable and undegradable protein, soluble protein, and heat damaged protein), ADF, NDF, mineral content and energy. In addition to these components, lactic, acetic, and butyric and propionic acids, pH, ammonia nitrogen, ethanol, and yeast and mold counts are also quantified.

Mainly reared for wool production. They require cooler environment to have better wool growth. The rearing is restricted to hilly regions where the weather is cool which helps in better wool production.

Management of Angora rabbit includes important aspects of breeding, feeding, heeding and disease control.

8.1. Reproduction

Angora rabbits of lighter breeds reach breeding age of 6-7 m, medium rabbits at 7-8m and heavier breeds at 8-10 m. Female Angora rabbits do not have a true oestrus cycle with a definite heat period. They may mate at any time of year. Ovulation in does is induced by mating and occurs about 10 -12 hours later to mounting and copulation with the bucks. No doubt there is no definite heat cycle in Angora rabbits, yet during certain periods breeding does are more receptive to bucks than other times of the year. Some of the signs of such receptive period are restlessness, rubbing of chin on the feeding or watering bowls and vulva may be slightly swollen and purplish red.

Food, furs, research, hobbies, pets – these are the major uses of rabbits around the world. It should be noted that rabbit production for meat and wool has become increasingly important in the last few years.

Angora wool rabbits are a commercial rabbit which is raised for its fine wool and meat as well, but primarily raised for wool production. Cooler climate is most conducive to raising this breed of rabbit. Angora rabbit does not differ from other breeds of rabbit except for its unusual length of valuable fur(wool). This modifies its raising compared to other rabbits.
 
The term ‘Angora’ qualifies those mammals which are covered with fur or wool composed of very soft hair of more than normal length – double or more than double the normal length.

Animal and poultry feed and fodder production management is a vital aspect of the agricultural industry, playing a pivotal role in sustaining livestock health and productivity. This intricate domain encompasses a myriad of practices, technologies, and strategies aimed at producing high-quality feed and fodder to meet the nutritional needs of various animal species, ensuring their optimal growth, development, and overall well-being. Feed and fodder production management involves the cultivation, processing, and formulation of feed ingredients tailored to the specific dietary requirements of different animals. From traditional practices to modern, technology-driven methodologies, this field has evolved significantly to address the growing demands of an expanding livestock industry. The cornerstone of effective feed and fodder management

“It  is not uncommon for animals to exhibit behavioral changes before an impending disaster. Wild animals often vacate areas, gather in strange groupings and sometimes will even enter into human habitats they normally avoid,” animal behavior expert Diana L.Guerrero said.Three days before the earthquake, thousands of toads roamed the streets of Mianzhu, a hard-hit city where at least 2,000 people have been reported killed.

Animal behaviour provides valuable information about health, welfare, reproduction, environmental adaptation and social interaction. Traditional observation is labour-intensive, time-consuming and vulnerable to observer bias. This chapter explains how machine learning automates behavioural analysis using video, sensor and bioacoustic data. It covers preprocessing, feature extraction, classification, clustering and recurrent neural networks for temporal analysis. Computer-vision techniques—including object detection, tracking and pose estimation—enable continuous and non-invasive monitoring. Case studies demonstrate applications in livestock management, wildlife conservation and laboratory research. The chapter also examines data labelling, model generalization, ethics, explainable AI, real-time processing and the integration of multiple behavioural data sources

Introduction
The behaviour of animals during restraining, handling, and feeding is a crucial aspect of animal husbandry and veterinary care. Understanding and interpreting their behaviour in these contexts is essential for ensuring the well-being of animals and the safety of humans involved in their care.
I. Animal Behaviour During Restraining
1. Fear and Anxiety: When animals are restrained, they often exhibit fear and anxiety. This behaviour can manifest as vocalizations, attempts to escape, increased heart rate, and sometimes aggressive actions. Understanding the signs of fear and anxiety in animals is essential to mitigate stress during restraint. Calm and gentle handling can help reduce the negative impact on the animal’s well-being.
2. Fight or Flight Response Animals: When restrained, may respond with a “fight or flight” reaction. They may try to flee or become defensive, potentially causing harm to themselves or the handlers. It is essential to anticipate this response and use appropriate restraints, such as halters or cages, to ensure safety for both animals and handlers.
II. Animal Behaviour During Handling
1. Trust and Bonding: The behaviour of animals during handling can vary depending on their previous experiences and the quality of their relationship with their caregivers. Animals that trust their handlers and have positive associations with handling are more likely to exhibit calm and cooperative behaviour. Trust is built through consistent, gentle, and respectful handling over time.
2. Aggression and Fear: Animals that have had negative handling experiences may exhibit aggression, avoidance, or fear during handling. This can pose risks to both the animals and the handlers. In such cases, it is essential to employ behaviour modification techniques and gradually desensitize the animals to handling procedures.

Animal Biotechnology

Biotechnology is defined as “the application of biological organisms, systems or processes to manufacturing and service industries” (Coombs, 1984).

It is also defined as “the application of scientific and engineering principles to the processing of materials by biological agents to produce goods and services” (Coleman, 1986).

Animalbiotechnologyis the application of scientific and engineeringprinciples to the processing or production of materials by animals to provide goods and services to human kind.

14.1 NEED FOR ANIMAL DISEASE INFORMATION SYSTEMS

Once the animal disease data are gathered, a few things need to be done with the data so collected. First, they must be managed and quality checked; Secondly, they must be analyzed to be understandable; and thirdly, they must be acted upon. For data to be analyzable and useful for decision-making, they need cautious management and quality control. An information system is the collection of data, people, procedures, hardware, software, files, and data required to accomplish an organized set of functions.

The constituents of an information system are:

• People – those who gather data, those responsible for data input and those responsible for data analysis

• A storage / retrieval / analysis system – which consists of computer hardware and appropriate software

• A feedback delivery system – mechanisms to ensure that processed data are fed back to data gatherers

Animal diseases on livestock farms can have significant impacts on animal health, farm productivity, and economic sustainability. Effective disease management and prevention strategies are crucial to minimize the risk of disease outbreaks and their consequences. Managing animal diseases requires a proactive and collaborative approach involving farm personnel, veterinarians, and animal health authorities. By implementing a combination of prevention, early detection, diagnosis, monitoring, rapid response and control measures, farms can effectively manage and mitigate the impact of diseases on animal health and farm operations. Outlined below are several prevalent animal diseases that can affect farms, along with prevention and management strategies.

Haemorrhagic Septicemia (HS)

It is an acute infectious disease of cattle and buffaloes characterized by sudden onset, high fever, edematous swelling of subcutaneous tissues particularly under the neck, pneumonia and fatal septicemia. HS is highly infectious OIE enlisted disease caused by two specific serotypes of Pasteurella multocida, the Asian serotype B:2 and the African serotype E:2. It causes huge economic losses to dairy farmers of Asia and Africa due to high morbidity and case fatality. The outbreaks of HS are quite common in North region of the country

Animals are exhibited in various ways and events like in fairs, judging shows, in circuses, in zoos and as performing animals. Some famous animal fairs in northern part of the country are Sonepur cattle fair of Bihar. It is the largest cattle fair of Asia, held on the confluence of holy river Ganges and Gandak annually on KartikPoornima in the month of November for the trade of animals such as Cattle, horses,goats,donkeys,camels,birds and elephants. Haathi Bazaar is the major attraction of SonepurMela. Nagaur cattle fair held during the months of January and February. It is the second biggest cattle fair in India. Pushkar Cattle Fair,popularly known as camel fair held for five-days between the months of October and November. Cattle shows are organized time to time where animals are judged for their different characteristics, selecting for their best type, possessing true breed characteristics, dairy conformation, good temperament, proper growth and development according to its age, with optimum condition of fleshing and free from defects. To take part in such shows animals are transported to different places. So, apart from knowledge of restraining methods, concept related to ageing, animal handling (flight zone, point of balance) animal behavioural consideration and welfare indicators are of much importance for transporting and presenting animals in any show.
