Анотация: The use of exogenous enzymes gives producers a greater opportunity to use different feed components in pig mixtures. In weaned pigs, amylase, protease and lipase activity is limited and changes in the degree of digestibility of added enzymes can improve productivity and reduce the cases of intestinal disorders caused by undigested nutrients. The practice of feeding pigs on farms in Europe is to include a more diverse group of feeds in the mix than in North America, where maize-soy mixtures are mainly used. This implies that the addition of mixtures of cellulases, hemicellulases and proteases, can improve the digestibility of complex carbohydrates and proteins from the more diverse cereals included. However, the use of various enzyme complexes is controversial in this respect. The main reason is the activity and type of enzymes, dosage and route of administration, age of the animals and their level of productivity. This requires preliminary testing of some enzyme additives with insufficiently proven results in terms of productivity.
