Abstract: The use of exogenous enzyme in ruminants is still the matter of debate among the researchers and the facts associated with enzyme feeding need to unravel. Ruminants were fed on low quality roughage having limited digestibility. Over period of interventions different approaches were developed to enhance digestibility by chemical, physical and biological methods. Exogenous enzymes were used to degrade of complex fibrous feed material and improve nutrient utilisation and production responses. Although ruminants have capability to degrade fibrous feedstuff due to microbial enzyme activity, but the structural polysaccharides such as cellulose, hemicellulose and lignin will be degraded up to some extent. Exogenous enzymes were used for specific substrate degradation, improve the efficiency of feed utilisation as well as to accelerate the decomposition and reduce the wastage production. Substantially exogenous enzyme improves nutritive value of feed can eliminate common anti nutritional factors present in unconventional feed resources. The information regarding source of enzyme, their activity and doses for animal feeding is reviewed. An attempt is made to explain mode of action and understanding functioning of exogenous enzymes in animal feeding system. This study was aim to redefine application of exogenous fibrolytic enzyme in animals feeding and related response on growth performance and milk production. Whether the use exogenous enzyme will profitable in dairy business and what will be the return of investment.
