The purpose of this work was to study the incidence of mastitis and its influence on quantitative and qualitative milk production. The biological material was represented by two groups of lactating cows: healthy cows (40 heads) and sick cows (9 heads). The obtained data were systematized and processed statistically. In the conducted study, three types of mastitis were highlighted: serous, catarrhal and purulent. The percentage of 18% of cases of mastitis in total population studied, the catarrhal form predominated with 8%, the serous form with 6% and the purulent one with 4%. Average milk production was 4526.05 kg in healthy cows, compared to sick cows in which milk production was 2251.44 kg and the statistically significant difference for p<0.01 it was of 2274.61 kg of milk. Fat and protein content in sick cows case was also reduced, respectively 2.68% for fat and 2.58% for protein. Improving the rearing system, maintaining hygiene in the barn and especially respecting the hygiene of the udder are some of the measures that must be adopted to be able to avoid such unpleasant situations.
