The microbial eco-system of the gastro-intestinal tract plays a very significant role in biocoiiversioii of ligiiocellulosic feeds into volatile fatty acids. Their role becomes inore iinportaiit when the diet given to the aiiiinals is of poor quality e.g. in the wild aiiiinals, which have to survive on the natural vegetation in the forests aiid in lean season the availability of iiutritious feed is scarce. Thus the aiiiinals have to depend upon the efficiency of the inicrobial eco-system of the gastro-iiitestiiial tract for extractiiig the inaxiinuin possible nutrients from such feeds. The literature available on the eco-system of wild aiiiinals is not much, but these studies conducted in different laboratories have been cornpiled aiid preseiited iiL this review. Most of the microbial groups reported iii wild a.iiimals are siinilar to those found in the domestic animals, but there do exist some exceptions in which new species of protozoa, bacteria and fungi have been reported. Some of these microbes are host specific. Therefore, the studies of the inicrobial eco-system of the gastro-intestinal tmct of wild aiiiirrals is very important and interesting.
