Overview

The global scenario of the livestock industry has seen tremendous growth. With growth the increased requirement for feed and usage of unconventional feeds to improve production with proper additives has also increased. In the face of antibiotic resistance and hormone residual scare, feed industry has now moved to more and more use of non- antibiotic growth promoters with emphasis on enzymes and their application in animal feeds to improve utilization and production.The use of enzymes as a feed additive has rapidly expanded. The economic and social benefits of enzymes have been well established and the future of feed enzymes is a bright one. However, further research is required if enzymes are to reach their full potential in the industry and to answer some of the questions, particularly those regarding the mode of action of enzymes, how best to match the levels of enzyme and substrate and how enzymes counter the variable environments in the animal's gut.
