In the conditions of the Republic of Belarus there was analyzed the effect of enzyme supplements "Belvitazim-400 granulate"and phytase in diets for fattening pigs on their nitrogen balance. We have shown results of research into the use of feed supplement 'Belvitazim-400 granulate' and phytase in the ration of piglets. The studied enzymatic preparation had the following activities: xylanase activity, not less than 1200; cellulase activity of at least 600; beta-glucanase activity not less than 1100. Feed supplements 'Belvitazim-400 granulate' and phytase help to reduce excretion of nitrogen into the environment with the metabolic products. During the balanced experiment there were studied following the following indexes: nitrogen content in the feed; nitrogen content in feces and contents nitrogen in the urine. Based on the obtained results of there was calculated the nitrogen content in the investigated samples and its digestibility in experimental animals.
