The udder inflammations decrease not only the biological value of milk but also cause economic losses because a somatic cells count in milk increases and the quality of milk deteriorates. Changes in the somatic cells count are influenced by the season of a year and it increases in winter as well as in the second stage of pregnancy and after reaching 9-12 years age. We used the increase of the somatic cells count in milk as the main indice for the diagnosing of udder inflammations in a farm by applying different reagents. The best of them are Dosile and California mastitis test (CMT). The main pathogenic aggent of infectious udder inflammations in private farms is Streptococcus agalactiae in 63.64 % cases, but in large scale farms - Staphylococcus aureus in 32.33 % cases. Sensitivity of microorganisms to different preparations was determined. As the most effective were ascertained Niphtiolum, Ampiocum, Brulamycinum, Lincomycinum hydrohloridum. The cows teats after milking must be disinfected by 1 % iodosept solution for the prophylaxis of udder inflammations and to decrease the getting of pathogenic microorganisms in the udder. Subclinic udder inflammations cause from 103.83 Ls up to 257.05 Ls losses per cow yearly.
