Abstract: Науково-технічний бюлетень ІТ НААН -№122 248 served in milk samples obtained in May, and the highest 539 ± 33.8 thousand in cm 3 in January (P<0.05).The "machine milking operator" factor influence on the average daily milk yield was 4.1 %, on the fat content 5.8 %, protein 1.2 % and on the content of somatic cells in milk 1.8 %.At the same time, the difference between the maximum and minimum values was: for a daily milk yield of 5.4 kg, for a fat content of 0.53 %, for a protein of 0.14 %, and for a somatic cell content of 403 thousand in cm 3 .The percentage of cows with mastitis also reliably depended on the machine milking operator.The greatest number of cases of cow diseases with mastitis was observed in the sixth group (29.3 ± 3.46 %), which was more than three times higher than in the eighth group (9.0 ± 2.65 %).
