Abstract
Providing the population of the country with high-quality food products of its own production is one of the most important tasks facing the employees of the agro-industrial complex of the country. Milk is such product. It also acts as a raw material for the processing industry, which produces a large range of dairy products, including cheeses. Special requirements are imposed on the milk used for the production of cheeses. Three groups of cows were formed: the 1st without taking into account the belonging to genealogical line (n=60), the 2nd cows belonging to the line Reflection Sovereign 198998 (n=15), the 3rd cows belonging to the line Wes Back Ideal 1013415 (n=15). The groups were formed taking into account age, live weight and milk productivity according to previous lactation by the method of balanced groups. All cows were on the third lactation. According to milk yield for lactation, the cows of the line Refl ection Sovereign 198998 turned out to be the best, according to milk yield for 305 days of lactation, cows of the 1st group (excluding line belonging). According to physic and chemical indicators, milk from cows of the line Refl ection Sovereign 198998 was inferior to milk from herdmates from other groups. Thus, in the milk of cows without taking into account the origin of the genealogical line, high indicators of nonfat milk solids and dry matter were observed, and in the milk of cows of the line Wes Back Ideal 1013415, a high content of fat, protein and lactose was noted. From the point of view of the fat : protein ratio, milk obtained from cows of the 2nd and 3rd groups was more valuable. During the production of Kostroma cheese, milk obtained from cows of the line Wes Back Ideal 1013415 turned out to be more stable, and cheese from this milk also received a high score according to an organoleptic assessment. In order to increase the production of high-quality cheese, it is necessary to pay attention to the breeding of cows of the genealogical line Wes Back Ideal 1013415.
