Abstract
Belmin feed additive is a metalloprotein complex of biologically active microelements. The use of belmin in the diets of highly productive lactating cows led to an increase in milk yield by 11,5%, the mass fraction of fat by 0,24, protein – by 0,06%, profit from the production and sale of milk – by 19,6%. Feeding a complex of chelate compounds of microelements led to an increase in the reproductive function of cows: the service period was reduced by two weeks, the insemination index decreased by 20%, the disease with mastitis – 2 times.
