In domestic animals, skeleton (Fig. 1-1) is a framework that is formed of bones, cartilages and ligaments binding together giving the specific shape, form and support to the body. In addition, the skeletal framework surrounds the major cavities of the body giving protection to other soft visceral organs of the body. There are three major parts of skeleton in the animal body (1) the axial skeleton (2) the appendicular skeleton and (3) the splanchnic skeleton.

The axial skeleton consists of the skull, vertebral column, ribs, and sternum. The appendicular skeleton consists of the bones of fore limb and hind limb

The splanchnic skeleton includes some of the bones embedded in the substance of visceral organs in the body such as os cordis in ox and os penis in dog.

Bones

The bones forming the skeleton of the body are of different shape, size, form and the constituting tissue material. The number of different types of bones of any species may differ in various stages of the growth of the animal. So also the numbers of various bones differ from species to species.

15.1 Introduction

An endoskeleton is a skeleton that is on the inside of the body of an animal. It is an internal supporting structure composed of mineralized tissue. The endoskeleton develops within the skin or the deeper body tissues. It participates in protection, helps in movement, provides shape and support and stores minerals like calcium. Gerringer et al. (2021) suggested that changes in skeletal structure are non linear and are driven by hydrostatic pressure, other environmental factors and evolutionary ancestry.

The skeleton of abdomen and pelvis (Fig. 4-1) consists of the lumbar vertebrae that form the dorsal boundary or roof of the abdomen, sacral vertebrae or the sacrum that forms the dorsal boundary or the roof of the pelvic cavity, the xiphoid cartilage of the sternum that provides attachment to the strong ligaments of the abdominal floor and the pelvic bone (pelvis) that forms the floor and lateral wall of the pelvic cavity.

Lumbar vertebrae

The lumbar vertebrae (Fig. 4-1 A) in ox are six in number. These are characterized by great size and form of their transverse processes. The other characteristic features of lumbar vertebrae are as below.

The body of the vertebra is much compressed dorsoventrally. The convexity of the cranial extremity and concavity of the caudal extremity of the body of the vertebra is moderate. The arch of the first lumbar vertebra is similar in size to that of the last thoracic vertebra but behind this the arches of the second to sixth lumbar vertebra gradually increase in height and width. The caudal notches are deeper than the cranial one. The intervertebral foramina of the first few lumbar segments are often double.

The fore limb is termed as pectoral limb or thoracic limb (Fig. 5-1). It is attached to the thorax by means of muscles of pectoral girdle (shoulder girdle). It is composed of four major segments, the shoulder girdle, arm, forearm and manus. The skeleton of shoulder girdle is formed by the shoulder bone, the scapula. The arm is formed by the arm bone the humerus. The forearm is formed by two bones the radius and ulna; and the manus is formed by the carpus consisting of six short bones –the carpal bones arranged in two layers, the metacarpus consisting of one large and one small metacarpal bones and the digits consisting of six short bones the phalanges and six small sesamoids arranged in two rows for each limb.

Shoulder girdle

The shoulder girdle (thoracic girdle or pectoral girdle) in general is composed of the scapula, coracoid and clavicle. In ruminants the scapula is well developed, the coracoid is in the form of a small rounded process fused with the ventral end of the scapula and the clavicle is absent or in some subjects it occurs embedded in the brachiocephalicus muscle cranial to the point of the shoulder. But this possibility is very rare. Hence, in ox only scapula is considered as the bone of shoulder girdle.

Scapula

The scapula is a flat triangular bone applied obliquely ventrad and craniad against the cranial part of the lateral wall of thorax. Its long axis extends from the fourth thoracic spine to the sternal end of the first rib. It presents two surfaces, three borders and three angles.

The bones of skull (Fig 2-1) are divided into two groups, as cranial group of bones and facial group of bones. Most of the bones of the skull are flat bones and a few are irregular bones.

Cranial bones

The cranial bones form the cranium that encloses and protects the brain and organs of special senses e.g. eye and ear. These bones include the occipital, sphenoid, ethmoid, inter-parietal, parietal, temporal and frontal. The first four of these bones are single and the rests are paired.

Occipital

The occipital is a single bone (Fig 2 -1C) and is situated on the caudo- dorsal aspect of the skull. It consists of three parts, the lateral parts are called lateral occipital, the basal part is called the basi occipital and the dorsal (squamous) part is called the squamous occipital.

The hind limb (Fig. 6-1) is termed as pelvic limb and it consists of four segments-the pelvic or hip region, thigh, leg and the pes region. The skeleton of pelvic region is formed by the pelvic girdle (os coxae). The skeleton of thigh region is mainly formed by a long bone (thigh bone) the femur and at its lower extremity is a short sesamoid bone, the patella. The leg region is formed by two long bones, the larger one the tibia and the smaller one the fibula. The last segment, the pes has three subdivisions as tarsus, metatarsus and digits. The tarsus has five short bones arranged in two rows on par with the carpus of fore limb. The metatarsus is constituted by two bones of which one is a long bone called the large metatarsal and the other a short small rudimentary bone the small metatarsal bone. The last part of the hind limb is the digits which are constituted by six phalanges and six sesamoids like those of the forelimb.

Cervical vertebrae

The skeleton of neck (Fig 2-1) is formed by the cervical vertebrae. These are seven in number. Of these, the first and second cervical vertebrae are highly modified and deviate greatly from the general architectural plan of the vertebrae. The third, fourth and fifth cervical vertebrae are similar and confirm the general plan of the vertebrae. The sixth and seventh vertebrae have some special characteristics but do not deviate much from the general plan. The general plan of vertebrae and the vertebral column has been described in the chapter on skeletal system under Part I on systemic anatomy. Hence, only regional specific characters of the cervical vertebrae are described hereunder.

First cervical vertebra (Atlas)

The first cervical vertebra (Figure 2-2 A) is called the atlas vertebra because in man it supports the globe of the head. This is an atypical vertebra and it deviates greatly from the general plan of vertebrae. The body and the spinous process are absent. The arch forms a bony ring from which two large curved plates, the wings project laterally. The ring encloses the vertebral foramen. It forms a part of the vertebral canal through which passes the spinal cord.

The skeleton of thorax (Fig. 3-1) consists of a bony cage formed by thirteen thoracic vertebrae constituting its dorsal boundary and roof, thirteen pairs of ribs forming its lateral walls, the costal cartilages which assist the ribs to form the lateral walls and the sternum forming its floor.

The general architecture of the vertebrae and the vertebral column is described in the chapter on skeletal system under PART ONE (Systemic anatomy) of this book. Only the deviations from the general characteristics of vertebrae as occur in the thoracic vertebrae are described here in the following account on the thoracic vertebrae.

Thoracic vertebrae

These are thirteen in number in ox (Fig. 3-1 A and B) The characteristic features of these vertebrae are the presence of capitular facets for articulation with the head of the rib and the greater development of dorsal spinous processes (neural spines).for attachment of muscles of the back and the supraspinous ligament that helps in the ligamentum nuchae to extend and suspend the head with the body trunk.

The effective application of agricultural meteorology in supporting agricultural decision-making and productivity relies heavily on the skills and knowledge of the individuals involved. As the agricultural sector continues to face growing challenges from climate variability, weather extremes, and changing environmental conditions, the need for well-trained and informed professionals has never been more pressing. Skill Advancement and Knowledge Empowerment (SAKE) is crucial for ensuring that stakeholders, including farmers, agricultural advisors, policymakers, and meteorological service providers, have the necessary expertise to harness the benefits of agricultural meteorology (Fig. 13.1). This chapter focuses on the education, training, and capacity-building initiatives required to enhance the skills and knowledge of individuals working in operational agricultural meteorology. It explores the various levels of education and training needed, from basic awareness and understanding of meteorological concepts to advanced technical skills and specialized knowledge in areas such as agrometeorological modeling, data analysis, and decision-support systems. The chapter begins by discussing the importance of SAKE in the context of agricultural meteorology, highlighting the key challenges and opportunities in this field. It then examines the different types of education and training programs that can be implemented to address these challenges, including formal education, vocational training, workshops, and online courses. The role of knowledge empowerment through access to relevant information, tools, and technologies is

Introduction

India possesses abundant human resources due to its demographic dividend. With a population of approximately 1.39 billion, rural areas are home to about 68.84% of the total population, constituting more than two-thirds (Census 2011, GoI). According to the National Sample Survey Office (NSSO) in 2019, about 58.3% of rural households rely on agricultural activities as their primary source of income. Despite the significant reliance on agriculture for livelihoods, the agricultural situation in India is challenging.

Introduction

India is known to possess a significant demographic dividend due to its large and growing population where the female population is estimated to be 586.5 million or above currently. This population is characterized by vast regional and cultural differences that create difference in terms of region and culture due to which any kind of generalization is not possible. Women play a crucial role in the growth of the economy and over the years, they had made a substantial impact and achieved status across different sectors both within the country and overseas. Women is a part of workforce but still there is a large population of women both in rural and urban areas that has dreams, but lack the opportunities to realize those dreams and take up their roles other than the household ones. In this regard, it is essential for to promote skill development and women empowerment. In order to upgrade employability and other skills among women, there is need to reduce the unemployment, demographic dividend, cultural and regional barriers and bridge the gap between talent and industry by various innovative methods.

Proactive involvement of society is essential to attain the sustainable development and bring the desired change in the society. Women in economically disadvantaged areas lack opportunities for employment and for self-employment due to various causes and sometimes women in need are on the look-out for affordable vocational courses that is not only of interest to them but also enables them to enhance their employability. Women from these areas can be equipped with the skills they need to increase their employability so that they can access meaningful and sustainable employment, and self employment through entrepreneurship. UNICEF is also assisting women to build stronger links with the private sectors so that they have sustainable market access for their artisanal goods including those who are running home based business.

Introduction

The 21st century has witnessed unprecedented changes in the global job mar ket, driven by technological innovation, globalization, and evolving industry needs. As traditional job roles become obsolete and new ones emerge, skill development has become paramount for both individuals and organizations. This paper explores the concept, importance, key elements, methodologied and challenges in skill development.

The ancient partnership between agriculture and weather forecasting, initially rooted in observational knowledge and rudimentary tools, has been fundamental to sustaining human populations for millennia. Traditional agricultural meteorology has diligently documented climate patterns, analyzed weather phenomena, and established empirical relationships between meteorological variables and crop yields. This foundational knowledge remains invaluable. However, the stark realities of the 21st century, dominated by the accelerating and often unpredictable impacts of climate change, necessitate a radical departure from conventional thinking. The comfortable reliance on historical data and linear projections is increasingly inadequate in a world characterized by unprecedented c limate variability, intensifying extreme weather events (as you‘ve extensively researched), and the urgent need for enhanced food security for a growing global population.
• The limitations of traditional agricultural meteorology become increasingly apparent when confronted with the complexities of climate change. For instance, relying solely on historical rainfall patterns for irrigation planning becomes precarious when those patterns are drastically altered by shifting climate regimes. Traditional pest and disease forecasting models, often based on established temperature and humidity thresholds, may fail to accurately predict outbreaks as these thresholds themselves are disrupted by climate anomalies. The need for real-time, localized, and predictive insights into the dynamic interplay between the atmosphere and agricultural systems has never been more critical.
• This is where the transformative power of emerging technologies steps in. The next generation of agricultural meteorologists stands at a pivotal juncture, tasked with leveraging advancements in diverse technological domains to revolutionize the field. Consider the sheer volume of data now available from a constellation of sources – weather satellites providing high-resolution global coverage, dense networks of ground-based sensors capturing hyperlocal environmental conditions, agricultural drones offering detailed field-level monitoring, and IoT devices collecting real-time soil and plant health parameters. This deluge of information dwarfs anything

″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.

The condition in the young subject is as follows:

The two parietals are united with each other and also with the interparietal and supraoccipital. The resulting mass is somewhat horse shoe shaped. Its occipital part (planum occipitale) forms the greater part of the posterior wall of the cranium and bears about its centre the tubersity for the attachment of the ligamentum nuche. From either side of this a line curves outward and divide the surface into an upper smooth area and a lower area which is rough for muscular technique. The upper borderjoins the frontal bone and concurs In the formation of the frontal eminence. The temperal part (Plana temporalla) are much smaller and are concave externally; they join the frontal above and the squamous temporal below. A median occipital crest extends ventrally from the external occipital protuberance.

Important by-products from rabbits are meat, wool, planner and skin. It can be made highly profitable if products are wasted because people do not have enough knowledge about their processing.

11.1. Slaughtering and Dressing

    1.    Rabbits are killed by one of two methods. The preferred method is dislocation of the neck. The rabbit is held firmly by the rear legs and head; it is stretched full length. Then with a hard, sharp pull, the head is bent backward to dislocate the neck. The rabbit can also be struck a hard, quick blow to the skull behind the ears. A blunt stick or side of the hand is commonly used to incapacitate the rabbit. Both methods quickly render the rabbit unconscious.
