1.1. Introduction

Wildlife management often requires interventions to safely handle and transport animals. Chemical restraint, also known as immobilization or tranquilization, is a technique widely used to facilitate these processes (Hernandez, 2014). It involves the administration of drugs to temporarily immobilize wild animals, allowing for various procedures such as veterinary medical examinations, tagging, relocation, or rehabilitation. This chapter provides an overview of the principles, methods, drugs, and considerations involved in the chemical restraint of wild animals.

It has been often stated that the most important techniques required by the zoo veterinarian are those used in the capture and restraint of the patient. These techniques have developed into a highly technical science (Clarke et al., 2014). In the early days of zoos, the only practical method was to manually catch and hold the patient. Modern techniques, however, permit a veterinarian to shoot a CO2 powered gun, which discharges a projectile syringe at an animal resulting in complete immobilization of the animal (Jacques et al., 2009). This is accomplished without any physical contact between the patient and his captors.

Animal husbandry faces increasing pressure to produce safe milk, meat and eggs while improving animal welfare and reducing environmental impacts. Traditional observation-based management is increasingly inadequate for large and complex livestock systems. This chapter introduces digital transformation through Precision Livestock Farming, which combines IoT devices, smart sensors, wearables, computer vision, artificial intelligence, machine learning and digital twins. Continuous animal-centred data enables timely decisions concerning health, reproduction, feeding, behaviour and welfare. The chapter explains how digital technologies can support early disease detection, efficient resource use and improved productivity across commercial and smallholder farms, creating more profitable, sustainable and welfare-conscious livestock systems.

13.1 The Normal Sperm Morphology

A mature spermatozoa is an elongated cell consisting of a flattened head containing the nucleus, a neck and a tail containing the apparatus necessary for cell motility. The sperm cell consists of the following parts covered by the plasmalemma or plasma membrane: 
    
13.1.1    Head
    
13.1.2    Neck
    
13.1.3    Tail / flagellum – The sperm tail consist of     
    
a.    Mid piece
    
b.     Main piece / Principal piece
    
c.     End piece

Sperm Plasma Membrane

The sperm plasma membrane is three layered membrane. It lies in close contact with the underlying cytoplasm and attached at three places i.e. over anterior outline of the sperm head, around the base of the head, in circle around the distal end of the midpiece (Jensen’s ring). This attachment causes creation of three compartments with probably no communication with each other. The sperm plasma membrane is invisible under normal light or phase contrast microscopy but can be visualized after addition of substances with light refractory index e.g. bovine plasma albumin or synthetic polysaccharides. It is very easily permeable to water but there is low permeability for inorganic cations (Na, K, Ca etc.) and even lower permeability for anions (NO3, Cl). Exposure of sperm cells to hypertonic media will cause the water to go from sperm to the surrounding media leading to shrinkage of sperm cell whereas exposure of sperm cells to hypotonic media will induce influx of water causing swelling of the sperm cell. The more water that goes into the tail the more it changes its shape and becomes rounded to give room for increasing amount of water. As the length of the tail decreases as it becomes round, the tail fibrils have less space and tail bends and coils within the membrane vesicle. Tail fibrils are not damaged initially and will continue to contract till the critical volume of bull sperm is 3.8-3.9 times of its volume in an isotonic solution. The swelling and change in shape of the spermatozoa are momentary processes and can be corrected if hypotonicity of the media is corrected before the sperm cells reach the critical volume for rupture.

Sperm membrane is responsible for maintenance of the intracellular biochemical environment. Damaged plasma membrane is responsible for the leakage of electrolytes and organic substances such as enzymes and may also lead to damage of sperm cells by foreign substances from the surrounding media.

• Mature sperm cells are undifferentiated cells which are the testicular product as well as indicators of testicular spermatogenic function.

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.

Introduction
Defining GLP: Good Laboratory Practices (GLP) are a comprehensive set of quality system principles designed to ensure the reliability, reproducibility, and integrity of non-clinical health and environmental safety studies. These principles establish a framework for planning, performing, monitoring, recording, reporting, and archiving studies. Adherence to GLP is crucial for generating data that can be trusted and utilized for regulatory submissions and scientific advancements.
Purpose of GLP
• To ensure the quality and integrity of non-clinical and clinical laboratory studies.
• To provide assurance that data submitted to regulatory authorities is truly reliable.
• To standardize procedures and practices in non-clinical and clinical studies.
Scope of GLP
• Primarily applies to non-clinical health and environmental safety studies.
• These studies often support applications for research or marketing permits for regulated products (e.g., pharmaceuticals, pesticides, food additives).
Key Elements of GLP
• Organizational structure and personnel responsibilities.
• Standard operating procedures (SOPs).

Different basic as well as advanced laboratory equipment need to be used in a laboratory while conducting experiments. Many of them like pH meter, laminar air-flow hood, viscometer, thermometer, magnetic stirrer, microwave ovens, incubators, sand-bath, water-bath, oil-bath, etc. are the basic and simple equipment which require to be used routinely while conducting experiments in a laboratory. However, basic knowledge of their operation, handling procedure, when to be used, how to be used, and more importantly what not to be done with it, etc. are essential for keeping them in serviceable condition as well as for the accuracy/precision in their operation. In this chapter, we will discuss about some of the routinely used laboratory equipment along, while some other sophisticated equipment will be discussed in other chapters.

pH Meter

A pH meter measures exactly the H+ concentration of a solution; thus indicates acidity or alkalinity of a solution with greater precision. Actually, it measures the difference in electrical potential between a pH electrode and a reference electrode, and display the results converted into the corresponding pH value. Electrode is the key part (rod-like structure, usually made of glass) of a pH meter, having a bulb at the bottom containing a sensor. The pH meters range from simple and inexpensive pen-like devices (portable/pocket pH meter) to complex and expensive laboratory instruments with computer interface (Figure 5.1).

Frequent calibration of a pH meter using the solutions of known pH (standard solution of pH 4.01, 7.00, 10.01, Figure 5.2), generally before each use, ensures the accuracy of the instrument. For very precise work the pH meter should be calibrated before each measurement. For normal use calibration should be performed at the beginning of each day. This is necessary because the glass electrode does not give a reproducible measurement over a longer period of time.

Introduction
Clinical physiology is the branch of medical science that focuses on understanding the functional processes within the body under both normal and disease conditions. It emphasizes how body systems respond to disease, injury, and therapeutic interventions, and, forms the foundation of many diagnostic and therapeutic practices in veterinary medicine.
Importance and scope of Clinical Physiology in Veterinary Medicine: Clinical physiology is indispensable and plays a pivotal role in veterinary medicine. The knowledge allows for early detection of diseases, select effective treatment plans, and improved outcomes for animal patients. It is used to monitor the effects of treatment interventions, adjusting medications or therapies based on the physiological responses observed in the patient. A solid understanding of cardiovascular physiology is essential to manage heart failure condition in dog, and, treating respiratory diseases in cats or gastrointestinal
disorders in horses, relies on the knowledge of respiratory and digestive physiology. Beyond treatment, clinical physiology also plays a significant role in preventive medicine. Knowing the normal range of heart rates, blood pressure, and respiratory rates in different species allows veterinarians to quickly assess whether an animal is in distress or experiencing a pathological condition, and allow for timely intervention. It is also critical in managing the health of populations of animals, such as in livestock farming, where maintaining optimal physiological function is essential for productivity and welfare. The major systems in the body - including the cardiovascular, respiratory, digestive, nervous, endocrine, renal, musculoskeletal, reproductive, and immune systems, can be affected by a variety of diseases, and clinical physiology provides the framework for understanding these effects. It encompasses the study of physiological processes across a wide range of species, including companion animals, livestock, wildlife, and exotic animals.

Introduction
The nervous system in animals is a complex group of highly specialized cells capable of collecting and transmitting information in response to external stimuli via receptors and highly specialized sensory organs. It aids in the regulation of muscle coordination, the release of hormones, neurotransmitters, and other chemical mediators, all of which facilitate numerous bodily activities.
The nervous system is divided into two systems: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system. Within these systems, there is another autonomic nervous system (ANS), which is distinguished by higher centers of the hypothalamus, midbrain, pons, and medulla, as well as tracts and nuclei in the spinal cord. The ANS is further divided into sympathetic and parasympathetic
systems, which help maintain homeostasis and activate emergency mechanisms in response to external stimuli. The brain is normally covered by three meninges: piameter, arachnoid, and durameter. These meninges create three spaces: the subarachnoid space (between pia mater and arachnoid), the subdural space (between arachnoid and dura mater), and the epidural space (between dura mater and the ligamentum flavum in the spinal canal). The subarachnoid space includes cerebrospinal fluid, which is isolated from cerebral blood by the morphological and enzymatic activity of cells with tight junctions that regulate intercellular diffusion and solute exchange inside the cells. These cells form a barrier known as the “blood-brain barrier”.
The blood-brain barrier works as a selective permeable membrane, allowing only certain chemicals and medications to pass through while excreting essential components from the central nervous system via energy-dependent efflux pumps like p-glycoprotein. These proteins are encoded by genes such as ABCB1, and mutations in them can result in severe effects such as Ivermectin poisoning in the Colie breed of dogs. Similarly, it aids in the relative isolation of the neurological system from the immune system by establishing an immune-suppressive parenchymal milieu. However, various infections, trauma, and developmental defects can result in underdevelopment or damage to different cerebellar structures. As a result, depending on the portion implicated, it might cause changed behavioral changes in animals such as muscle incoordination, depression, and paralysis. These clinical symptoms may be excitatory.

CONTRACEPTION DUE TO MISALLIANCE AND TERMINATION OF PREGNANCY IN BITCHES

It is obvious that breeders maintain varieties of breeds but mismating do occur within their own premises and sometimes by unwarranted stray animal.

Misalliance complicates too many other problems.

Incidence of mismating is 15 to 20 percent in canine breeding.

3.1. Introduction

Various procedures performed on reptiles often necessitate chemical restraint or general anesthesia. Even routine tasks like physical examination and transportation can pose challenges, particularly with large or uncooperative reptilian patients. For safety reasons, venomous species are typically evaluated under chemical restraint. The respiratory anatomy and physiology of reptiles differ significantly from those of more familiar mammals, influencing their response to commonly used anesthetic agents. Historically, anesthetics recommended for reptiles had notable metabolic effects, but inhalant anesthesia has become more popular in recent times. Nonetheless, in species capable of anaerobic metabolism, induction with these agents may not be feasible (Girling 2013).

AI-enabled livestock technologies can improve productivity, health monitoring, animal welfare and environmental performance, but they also raise significant ethical and governance concerns. This chapter examines data ownership, privacy, algorithmic bias, transparency, accountability, cybersecurity, socioeconomic inequality and animal well-being. Precision livestock systems continuously monitor animals through sensors, computer vision, machine learning and IoT networks, enabling preventive decisions and automated interventions. However, excessive dependence on algorithms may reduce human oversight and treat animals merely as data-producing units. The chapter advocates an interdisciplinary framework for responsible AI that aligns innovation with animal-welfare standards, farmer interests, social values, equitable access, regulatory requirements and long-term environmental sustainability.

10.1. Classification of Primates

The classification of primates is a complex topic that has been revised over time as our understanding of these fascinating creatures has evolved. Here’s a breakdown of the current classification system:

10.1.1. Order: Primates

Primates are an order of mammals that includes lemurs, lorises, tarsiers, monkeys, apes, and humans. They are characterized by a number of shared features, including:

• Opposable thumbs: This allows primates to grasp objects and manipulate their environment.

• Forward-facing eyes: This provides primates with depth perception, which is important for arboreal locomotion and foraging.

• Enlarged brains: Primates have relatively large brains for their body size, which is associated with their intelligence and complex social behaviors.

• Reduced sense of smell:Compared to other mammals, primates have a weaker sense of smell. This is thought to be due to their reliance on vision for foraging and social interaction.
