Metabolic diseases are more common in highly productive cows. The use of feed additive No. 1 led to positive changes in the health and milk productivity of cows in SPH «Nm.Vakhitova». In comparison with the control group, an increase in the mass fraction of fat and protein, a decrease in somatic cells and ketone bodies were observed in all experimental groups over the entire period of the experiment.
