To study the effectiveness of the use of the liquid feed additive "Active mix" VM 10/20 for relieving the lack of vitamins and trace elements in calves

The results of a study of the effectiveness of the use of the feed additive «Active Mix» VM 10/20 for relieving the lack of vitamins and trace elements in the body of calves are presented. When creating this feed additive, a number of new approaches were applied aimed at increasing the digestibility of vitamins and trace elements. The study was performed on calves of the Holmogorsky Holstein breed aged 1 month, who had manifestations of vitamin and trace element deficiency. During the work, the animals of the experimental group received this feed additive for 4 weeks according to the recommended scheme. At the same time, the content of copper, zinc, manganese, cobalt and iron in their blood was determined, as well as the content of vitamins A and E. There was a significant increase in these indicators in the blood of calves of the experimental group compared with animals of the control group (who did not receive this feed additive). There was also an improvement in the general condition of the calves of the experimental group, which indicates the successful relief of the lack of vitamins and trace elements. Thus, the liquid feed additive «Active Mix» VM 10/20 is effective for the treatment of hypomicroelementosis and hypovitaminosis in young cattle.
