Preface The state of Jammu & Kashmir is an agrarian state and about 80% of population is associated with livestock farming. This sector plays an important role in socioeconomic upliftment of rural community. This manual has been prepared by the Principle Investigator NRDMS/DST- project with the support of senior Faculty members. It will be used as a tool of interventional strategies for prevention and control of parasitic zoonoses of livestock and their rearers belonging to socio-economically poor communities by imparting knowledge through training of field veterinarians. It will be useful as a conceptual guide as well as reference material for trainers. Moreover, some part of it could be used as reading material for participants. The various aspects of livestock farming, management, disease diagnoses and prevention and control measures have been included into the training manual. Livestock rearing are popular because of the prolificacy, less investment and minimal skills that are needed for success. In addition, state is an agrarian and livestock farming play an important role in livelihood of rural people. However, the present manual focuses on some modern technological aspects of disease diagnoses, measures for prevention and control, care and management of livestock for enhancing the productivity.

Helminths include the nematodes (roundworms), trematodes (flukes) and the cestodes (tapeworms). The adult worms live in intestine and discharge the eggs or larvae that comes out with the faeces. Therefore, diagnosis is based on the detection of eggs or larvae in faecal samples. Overview of Nematode infections in humans and animals The phylum Nematoda, (roundworms), is the second largest phylum in the animal kingdom, encompassing up to 500,000 species. Members of Nematoda are elongated, with bilaterally symmetric bodies that contain an intestinal system and a large body cavity. According to a report approximately 60 species of roundworms parasitize humans. Intestinal roundworm infections constitute the largest group of helminthic diseases in humans. According to 2005 report of World Health Organization (WHO), approximately 0.807-1.221 billion humans suffers from ascariasis, 604-795 million from trichuriasis and 576-740 million from hookworm infections worldwide.

Introduction Mankind has been utilizing different animal species from the dawn of civilization for a variety of purposes viz., production of milk, meat, wool, egg and leather. Apart from these, various animal species are also used for draught power, companionship, entertainment, research experimentation, sports, security etc. Livestock sector plays a crucial role in rural economy and livelihood. As per report of the working group on animal husbandry and dairying, 11th five year plan: 2007-12, the livestock sector employs eight percent of the countries labour force, including many small and marginal farmers, women and landless agricultural workers. Milk production alone involves more than 30 million small producers, each raising one or two cows or buffaloes. The organic fertilizer produced by the sector is an important input to crop production and dung from livestock is widely used as fuel in rural areas. Livestock also serves as an insurance substitute, especially for poor rural households; it can easily be sold during time of distress.

Livestock sector has emerged as one of the key components of agricultural growth in developing countries in last few decades. This sector plays a significant role in the economic progress of India as it contributes 26% to the agricultural GDP and provides employment to around 18 million people. Over 70% of the rural households in India depends on livestock farming for supplementary income and is considered as an important instrument in poverty alleviation. It provides the major extra contribution to agriculture through manure, fuel fertilizer, apart from meat and milk that grant a regular supplementary income and employment not only to producers but also to huge size of the population engaged in secondary and tertiary business related to livestock. The economy of Jammu and Kashmir is also agriculture dependent and is the main occupation of majority of the rural people who earn their livelihood from it. Census figures 2011 signify that about 73% of the population of J&K lives in rural areas and are associated with agriculture and allied sectors including livestock rearing as main occupation.

Small ruminant sector, after agriculture, is the second largest means for economic sustainability and livelihood in India. It contributed Rs. 32000 crore to the gross domestic product of India in 2012 -13 despite having a potential to contribute over Rs. 150,000 crore but there are certain lacunae in system which act as its growth inhibitor. Small ruminants are the main source for rural economies due to participation of women (70% of total) and weaker sections of the rural society. Thus there is urgent need for formulating policies to support the development of the small ruminant sector.   Sheep and goat husbandry is a tool for poverty alleviation of the rural masses because of wide adaptability with low investments, high fertility and fecundity, low feed and management costs, higher feed conversion efficiency, quick pay off and low risk in comparison to large ruminants. The above traits of small ruminants need to be exploited for economic upliftment of small farmers.

The livestock play a significant role in generating gainful employment in rural areas, particularly among the landless and marginal farmers. The Jammu region of state of Jammu and Kashmir possesses a huge livestock population which is maintained under different management systems. The region has a vast diversity in agro-climatic conditions (comprising low altitude, middle altitude and high altitude), and animal husbandry and pasture management practices. Despite having huge livestock, the production potentials are very low. There are various factors related with low production and among them parasitic diseases rank very high.

Feeds and feeding of dairy animals are arguably the most important part of the dairy farm management. And it is not only what we feed that is important but how we manage our feeding is equally as critical. What we feed today not only determines the animal’s milk production but also influences their entire lactation cycle that follows. Dairy animal feeding with balanced ration influences health status, reproductive, productive performance and better economic return in organic environment, all of which are critical to a profitable and sustainable dairy business as well as welfare of the dairy farmers. Feed costs currently account for around 45 percent of total milk price on average, with concentrates representing around 35 percent and forages around 10 percent.

Small ruminants is a composite term used for sheep and goats. Throughout the developing countries, small ruminants make a very valuable contribution, especially to the poor in the rural areas. These contributions range from precious animal proteins (meat and milk) to fibre and skins, draught power in the highlands, food security and stable households. By and large, the importance and extent of the contributions are inadequately understood as a consequence of which these valuable genetic resources continue to be generally neglected. Research and development investments to improve the relatively low level of contribution do not match their potential importance, the contribution to nutritional security and livelihoods of the poor in rural areas. Species like goat and sheep are of short-generation interval, have a high prolificacy rate and require less land, investment and operational expenses and are better suited to the resource endowment of the poor.

Collection of faecal samples: To diagnose gastro-intestinal parasites of ruminants or other animals, the parasites or their eggs/larvae must be recovered from the digestive tract of animal or human or from the faecal/stool material.   The faecal samples for parasitological examination should be collected from the rectum of animals. If rectum samples cannot be obtained, fresh faecal samples may be collected from the pastures. Several samples should be collected and immediately dispatched to the diagnostic laboratory in suitable containers such as:
