Prevention of mastitis in cows during the dry and post-partum periods using intrasan

The aim of the work was to study the incidence of mastitis in cows in the agro-industrial complex of the Kirov region and to evaluate the effectiveness of intrasan for the prevention of udder inflammation in the dry and postpartum periods in cows who had mastitis during lactation. The results of the study showed that the incidence of cows with subclinical and clinical mastitis at the enterprises of the agro-industrial complex of the Kirov region remains high. A positive result was obtained using Intrasan during the dry period, which is confirmed by a lower level of somatic cells and immunoglobulins on the 15th day of lactation and a higher preventive effect of udder inflammation.
