The comparative characteristic of the fat content of milk in cows, taking into account the season of the year
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.

The comparative characteristic of the milk quality indicators at the breeding farms of the Totemskiy district in the Vologda region (taking into account the seasonality)
The article presents the results of studies devoted to the milk quality indicators: mass fat fraction, mass protein fraction, mass fraction of solids non fat, somatic cells in modern breeding farms of the Totem district in the Vologda region. In 2019 the quality milk indicators were determined from cows in the “Rodina” SPK (collective farm), the “Totemskiy” SPK and the “Velikodvorye”collective farm. Based on the data obtained the research was formed, the comparative characteristic of the milk quality indicators was carried out taking into account the season of the year. 19503 samples were examined for the analyzed time period. Milk sampling was carried out in accordance with the monthly control cow milking schedule and tested on a Combi-Foss infrared spectrometer. The device from FOSS (Denmark), which was used to analyze the quality of milk is the world leader in the production of analytical instruments. The main advantages of this milk analyzer were high measurement accuracy and obtaining several indicators at the same time. According to the results of the study for 2019 all analyzed breeding farms of the Totemskiy district in the Vologda region revealed high quality milk indicators that meet the requirements of GOST. The highest indicators of milk quality were noted in autumn. The content of somatic cells corresponded to the Russian standard GOST R 52054-2003 “Natural cow’s milk - raw material. Technical conditions “. According to the results of the study for 2019 all studied breeds revealed high quality milk indicators that meet the requirements of GOST throughout the year.

The influence of cows’ breeds on the quality indicators of milk
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
taking into account the season of the year. As a result of the research, all analyzed
breeds have high quality indicators of milk that meet the requirements of State Standard
throughout the year.

Influence of the season on the mass fraction of protein and urea in the milk of cows of black and motley breeds with different methods of maintenance and milking technologies
The article presents the results of studies on the urea content and the mass fraction of protein in the milk of cows with a tethered and loose method of maintenance, taking into account the technology of milking cows, depending on the season. The optimum content of urea, protein in cow’s milk is established in summer period, the greatest one is revealed in winter period with all milking methods and maintenance technologies
