In experiments were used crossbred pigs (F-1: KBхL) separated by analogy into three groups: control and two experimental. Found that the use Protosubtilin G3x comprising complete feed promoted an increase in the average daily live weight gain on 8.1-13.2%. Animals of experimental groups, due to better protein digestibility than "lost" nitrogen in the feces and retention of nitrogen in them was higher than the control on 8.19-12.99 g per head per day. Biochemical indicators until the blood of experimental animals were within the physiological norm. Produce cost of feed to 1 kg for growth indicators in two experimental groups were lower relative to the control group at 7.5-11.8% respectively. Indices of the cost of the exchange energy for 1 kg live weight gain of pigs would also whether below-control at 5.1-5.6%. Inclusion of the enzyme preparation in amount of 50-75 g/t (depending on the ingredient composition) will reduce the proportion of expensive high protein components input when increasing the energy value of the feed. Then studied the effectiveness of domestic enzyme preparation GlucoLux-F feeding pigs. Experimental data indicates that the additive GlucoLux-F in complete feed increases the digestibility of nutrients, thereby increasing the energy value of the feed. It was found that the use GlucoLux-F contributed to the increase of average daily liveweight gain to 9.8-10.3% increase in digestibility of nutrients, reduce feed costs per unit of growth by 9.0-9.3%. Through the use of GlucoLux-F possible depreciation of the component composition of feed.[Горнеев, А. Роксазим® G2 - мультиэнзимный препарат для птицы и свиней / А. Горнеев, А.
