Clinical and physiological condition and meat productivity of calls when used liquid feed additive “Active Mix” VM 10/20 on

The article presents the results of studies on the effectiveness of using the new liquid vitamin and mineral feed additive “Active Mix” VM 10/20 when raising bulls up to 15 months of age. When creating this feed additive, new approaches were used aimed at increasing the digestibility of vitamins and microelements. The study was carried out in JSC “Put Ilyich”, Zavyalovsky district of the Udmurt Republic, on 20 bulls of the Holsteinized Kholmogory breed, which were divided into 2 groups, experimental and control, each containing 10 heads. Starting from one month of age and until reaching 15 months, animals in the experimental group were given a feed additive according to the recommended schedule. Its use made it possible to quickly (within the 1st month of administration) stop the manifestations of a deficiency of these substances in animals. In bulls receiving the feed additive, a more intense increase in live weight, an increase in meat productivity and meat quality were noted compared to the control.
