Small ruminants are able to utilize the lingo-cellulosic materials and convert them to animal products of high nutritional value viz. meat, milk, wool/fur, hide and manure. However ruminants are also contributing towards green house gas emission. Like large ruminants, these fore gut fermenters also harbor a dense and diverse microbial population belonging to different group of flora and fauna. The mammalian system is devoid of enzymes cellulase to degrade structural carbohydrate while ruminants are able to degrade them by the enzymes elaborated by symbiotic microbes inhabiting in the rumen. Importance of small ruminants in Indian economy lies in their smaller size, which is easy to graze and manage. Sheep and goat production is an integral component of rural economy of India and serves as major source of economic sustenance for weaker segments of the society in the hot semiarid and arid region. Sheep and goats are closely related since both belong to subfamily Caprinae whereas they are separate species. However, minor differences also exist in their anatomy, physiology, grazing behavior, etc. Sheep as individuals and breeds are more sensitive to environmental changes than other domestic animals but as a species they thrive everywhere. The inherent characteristics of goats such as resistance to dehydration, wider choice of vegetation, and wide-ranging feeding habits with preference for browse species, enable them to perform better than sheep in regions of scanty rainfall. Furthermore, goats appear to digest fiber more efficiently than sheep. Studies are required to delineate differences in microbial population between sheep and goat which might be helpful in enhancing productivity of the species reared under changing climatic conditions. Modern biotechnology based tools are widely applied to unravel complexities of microbial communities harboring rumen and their functions and interaction among different microbes.
