Abstract

Nowadays, the number of livestock products in the world has increased, and this has led to strategies to increase the production of livestock products. The use of enzymatic biological methods to deal with feed-related problems has been the focus of nutritionists due to their low cost and environmental pollution. Solid and protected capsules to be used. Including cellulose enzyme, which is composed of three enzyme complexes (exoglocanase, endoglucanase and beta-glucosidase) and is responsible for digesting cellulose. The lignin-degrading enzymes are oxidases such as lacase and manganese peroxidase. Adding fibrolytic enzymes to the diet of Fresh cows increases milk production due to its positive effect on nutrient intake, digestibility, ruminal fermentation and microbial protein synthesis, and in the diet of growing beef, it stimulates feed intake and Its effects. They create a positive in ruminal fermentation. Also, the addition of enzymes to the diet of lambs increases daily weight and the ability to digest nutrients without affecting feed intake.
