Immunostimulators as a way to implement nonspecific resistance of cows to mastitis

A method for the prevention and treatment of cow mastitis using biologics developed by scientists of the Chuvash State Agrarian University: Prevention-N-E and Prevention-N-B-S, as well as a homeopathic medicine for the treatment of mastitis Mastinol. Prevention-N-B-S showed the greatest preventive effect among the tested biologics, however, this difference with Prevention-N-E was insignificant (P>0.05). Treatment of cows whose mastitis prevention with the use of immunostimulants proved ineffective was carried out in the 1st and 3rd experimental groups. Thus, the therapy of cows with mastitis showed that the recovery of the cow of the 1st experimental group, which was treated with Prevention-Nth, occurred after 4 ± 0.08 days, which is 7 ± 0.52 days less than in the 3rd experimental group, where Mastinol was used. The results of this study have shown that the use of immunostimulants in the prevention and treatment of cow mastitis is advisable. The studied biopreparations contributed to the activation of the indicators of the cellular link of the nonspecific protection of the body. Thus, in the prevention of cow mastitis, Prevention-N-B-S demonstrated the most pronounced corresponding effect from among the tested biopreparations, and in the treatment of mastitis - Prevention-N-E.
