DIGESTIBILITY OF NUTRIENTS OF DIETS WHEN FEEDING BULL CALVES WITH FEED ADDITIVES
View through CrossRef
The article presents the results of studies on the digestibility of dietary nutrients with partial replacement of concentrated feed with protein-vitamin-mineral concentrate (PVMC) and complete replacement with compound feed concentrate (KK-65) in different periods of growing and fattening bulls for meat. The studied feed additives were used to increase the productivity of animals by enriching concentrated feed, improving the digestibility of feed nutrients. It has been established that the use of partial replacement of concentrated feed with protein-vitamin-mineral concentrate (PVMC) at 7–12 months. age and the introduction of compound feed concentrate (KK-65) instead of concentrated feed from 13 to 18 months. age in Holstein bulls had a positive effect on the digestibility of nutrients. A significant increase in the digestibility coefficients of crude protein by 2.8 %, crude fat by 1.7 % and crude fiber by 2.8 % in relation to the control group was established.
