enzyme preparations
The enzyme preparation can improve the digestibility of the feed, reduce the residual amount of nutrients in the digestive tract, shorten the residual time, and indirectly reduce the growth chance of the pathogenic bacteria, thereby achieving the effect of disease resistance and disease prevention.
