Recent Knowledge on the Use of Feed Enzyme in view of the quality of feed resources

Abstract

Several issues that would be challenging upon practical use of dietary enzyme were proposed and discussed. Five issues were raised in view of current feed resources and quality. Whether the dietary enzyme supplementation to ruminant animal is worth it was discussed by comparing the type of enzyme on rumen hydrolysis as well as milk production performance. A derivative action following the enzyme specific hydrolysis was discussed when it would be probably occurring in feed having complex substrate. Single or multiple combination enzymes were discussed whether and when each would be worth. Finally, whether the effect of enzyme would be different by either sex or age of animal was also discussed.

Key words: Dietary enzyme, Dairy cow, Derivative hydrolysis, Multiple enzymes, Age of poultry
