These cattle breeds are specially adapted to different agro-climatic conditions of India and their genetic diversity is due to the process of domestication over the centuries. There is decrease of 4.10% in cattle population and 3.14% in cattle genetic resources of India as compared to the quinquennial livestock census. The exotic / crossbred population has been increased by 20.18% during the period of last census while population of indigenous cattle has been decreased by 8.94% during the same duration. The reasons for depletion of native breeds includes crossbreeding with exotic breeds, economically less viable, loosing utility, reduction in herd size and the large scale mechanization of agricultural operation. The native breeds need to be conserved for genetic insurance in future, scientific study, as a part of our ecosystem, cultural and ethical requirements and for energy sources in future. The indigenous breeds of cattle posses various unique characteristics such as the presence of unique genetic variation in HSP70 gene family, carry a ‘thermometer gene’ and presence of A2 allelic variant in cow milk, which makes them well adapted to the tropical climate. The conservation includes the preservation along with up-gradation (improvement) of the genetic potential and management of a breed for use in future. The effective management of indigenous cattle resources includes identification, characterization, evaluation, documentation and conservation. The future strategy should be to combine genetic improvement and conservation. Establishment of regional gene banks and people’s participation by involving breeders, communities, gaushalas, NGOs and other relevant stakeholders in conservation programs. For more effective conservation measures, proper coordination and integration among various agencies (ICAR, SAHD, SAUs, SVUs and Research Institutes) is highly needed. “National Consortium of Partners’ comprising different stakeholders should be formulated for conservation of indigenous breed resources with a holistic approach.

The technical aspects of conservation of animal breeds is a loss of cultural identity and heritage of that community which are at the verge of extinction were considered jointly (Belew et al., 2016). Losing these breeds is like losing in 1980 by FAO and UNDP. The efforts in this direction a global insurance policy against future threats to food in India were started with the establishment of National security (Shah et al., 2016). It is estimated that in the last Bureau of Animal Genetic Resources (NBAGR) Karnal in hundred years about 22% of known livestock breeds have 1984 under the ICAR (Tomar, 2004). The preservation of become extinct and another 27% are at varying degrees a breed is required when it reaches an endangered level of risk (Rege and Tawah, 1999). It is further reported that of a population near to extinct. The preservation covers approximately two breeds of poultry and livestock are lost the continued maintenance of genetic variability, whereas, each week (FAO, 2007). The indiscriminate crossbreeding the conservation includes the preservation along with between exotic breeds and indigenous animals has been up-gradation (improvement) of the genetic potential and adjudged as major cause for the losses, as well as the risk to management of a breed for future use. existing breeds. According to Hanotte and Jianlin (2006), though it may be too late for many livestock and poultry The different indigenous breeds of farm animals are breeds in Europe, optimism in the developing world about essentially the result of evolutionary processes, they slowing down the loss of both diversity and indigenous have adapted to the harsh climatic conditions with low animals is high. It is believed that continuous import of management inputs in terms of feeds, fodder and health highly productive animals from developed countries is the care, capable to convert low quality feeds and fodder most significant threat to domestic animal diversity in the more efficiently into animal products and better adapted developing world. Therefore, conservation of indigenous to withstand tropical diseases. They are integral part of animal resources has been projected as a suitable method agriculture. These breeds are now subject to fast genetic for slowing down the loss in livestock breed diversity degradation and dilution because of unplanned breeding through extinction. and introduction of exotic germplasm through cross breeding (Groeneveld et al., 2010). As a consequence some indigenous breeds are becoming endangered and Indian Cattle Wealth there is depletion of good native germplasm which was The livestock census conducted in India in 1951 revealed having unique quality of disease resistance and heat a total cattle population of 155.3 million, which gradually tolerance.
