Abstract
The dynamics of body weight from 3 to 7 months of age are considered; indicators of slaughter at the ages of 3 and 7 months. sheep of the Kuibyshev breed when included in the diet of 1.5 and 2.0 g of metasmart. It was shown that metasmart supplements had a positive effect on body weight gain and slaughter rates. It was noted that the addition of 2 g of metasmart to the diet was more effective.
