... cients of digestibility of nutrients: dry matter -by 1.7 and 1.0 %, crude protein -by 1.5 and 1.2 %, crude fat -by 1.2 and 0.8 %, crude fiber -by 2.1 and 1.6 %, nitrogen-free extractives -by 1.7 and 1.4%, compared with animals of the control group. The nitrogen balance was positive in all groups, the use of nitrogen taken by the experimental sheep was higher in the experimental groups than in the control group by 1.82 and 1.50 %. The use of calcium and phosphorus by animals was also higher in the experimental groups, and exceeded the control indicator: for the use of calcium by 2.32-3.71 %, phosphorus by 3.42-4.27 %.
