Abstract
The article discusses enzyme preparations Natuzyme 50, Rovabio Max AP, Rovabio Max Advance P, Rovabio Excel AP, Vilzim, Fekord — 2012 — C 2 group, their digestibility and effectiveness in the composition of compound feed for carp are determined. The best indicators of absolute growth, relative growth and specific growth rate in underyearlings of carp were obtained when feeding with compound feed with the introduction of the Natuzyme 50 enzyme preparation at a dosage of 50 g / t, while the feed ratio decreased by 31.3 % in relation to the control sample. In terms of protein digestibility, the enzyme preparation Natuzyme 50 at a dosage of 50 g/t also showed the best result, it gave results 32.4 % higher than in the control, which led to an increase in protein in carp muscles by 5.2 %.
