In dairy farming, when breeding dairy breeds of cattle, milk quality is an important factor, milk fat content in particular. According to the results of the research, on 3 farms of the Vologda region for the period from 2017 to 2019, taking into account the season of the year and basing on the comparative characteristics, high values of the mass fraction of fat in milk samples of cows have been revealed in autumn. On average, the farms have established high quality values of the mass fraction of fat that meet the state standard requirements.

In modern conditions of breeding dairy breeds of cattle, an important

element of the study is the influence of breed and quality indicators of milk. The studies

were carried out in 2019 on the basis of the SHPK “Plemzavod Maysky” Vologda region

on the quality indicators of milk from Ayrshire and black-and-white cows in the amount

of 15663 milk samples. Based on the results of milk samples, a research database on

milk quality indicators was formed and a comparative characteristic was carried out

 The article presents the research results on the quantitative and

economic situation of the livestock sector management, the problem of preserving the

number of dairy cattle breeds and increasing cow’s milk productivity is quite pressing.
