Mastitis is the most unprofitable disease in dairy cattle breeding. It dominates all known forms of dairy farm organization. In Ukraine, farm dairy companies are reviving. Their veterinary management is taking shape, which has a significant impact on product quality. It is of great significance to study the indicators of pre judgment of milk quality for such enterprises to understand their position and role in the domestic dairy industry.
This paper introduces the research results on the dynamics and etiology of cow mastitis in «Podilska Marka» farm, Kamianets-Podilskyi district, Khmelnytskyi region. The highest frequency of mastitis (13%) was observed in summer (June to July) and winter (January). A maximum of 14 (6%) animals was sick repeatedly. Starting from calving, 20% of cows were sickest from days 121 to 305. The maximum recurrence of mastitis was observed in the last third of lactation and reached 10%. Among clinical mastitis, the serous form was more frequently observed. Purulent-catarrhal mastitis was determined in only 2% of sick animals. According to the clinical course, the following mastitis were observed: staphylococcal - 40.1%, coliform - 30.8%, streptococcal - 21.6%. In subclinical mastitis, Streptococcus agalactiae was isolated from 39.6% of pathological material, Staphylococcus aureus from 30.2%, and Escherichia coli from 26.5%.
