Abstract

The use of commercial exogenous fibrolytic enzymes (cellulases and xylanases) has been widely used in animal production, in order to complement the activity of the endogenous enzymes, to achieve an increase in milk production response. In this research, we intend to utilize as an alternative the use of exogenous enzymes obtained from the spent substrate of Pleurotus ostreatus in order to evaluate the productive parameters of goats. The results showed that the inclusion in the diet of this enzymatic extract had an effect on daily weight gain, milk production, and consumption. This suggests that the enzymatic extract obtained from the spent substrate of Pleurotus ostreatus may be an alternative to improve the productive parameters of goats. Keywords: milk, extract enzymatic, goat.
