Abstract

This article presents the results of clinical trials of the supplement “PREVAX”. The results of the additive tolerability study «PREVAX» are presented in high-producing cows, the results of preventive and therapeutic use of the supplement “PREVAX” in high-producing cows with subclinical and clinical mastitis, and the effect of the supplement on milk parameters and milk production. The application of the additive “PREVAX” for the prevention of mastitis has a positive effect. The administration of the supplement orally through the watering system at a dose of 1 ml per 100 litres of water for 60 days was found to reduce the incidence of mastitis in cows by 70%. Administration of the additive “PREVAX” to cows with the clinical form of mastitis at a dose of 4 ml per 100 litres of water in the background of classical therapy with Mamikur at a dose of 10 ml intra-cisternally is well tolerated by the animals, gives a pronounced positive clinical effect and leads to normalisation of somatic cell count in milk on the sixth day of treatment. At the same time, treatment without the supplement “PREVAX” only led to a similar result after 12 days of treatment.
