I am interested in ruminant animal (Cattle, Buffaloes, sheep and Goat) in its microbial anaerobic ecosystem to enhancement our understanding of rumen microbiology by alternative means of manipulating the microbial activities or modulating the populations of rumen microorganisms by Microbiological, Biotechnological and Biochemistry changes in in vitro or in vivo trials for improving animal nutrition which reflect the animal productivity (Meat, Milk and Wool).
