THE INFLUENCE OF GENETIC FACTORS ON THE SALE OF DRY MATTER OF FEED BY HIGHLY PRODUCTIVE COWS OF THE KOSTROMA BREED
The current situation in our country obliges us to take measures to import substitution and increase the rate of production of our own products. There is a possibility that in the near future we will have to focus not on the purchase of imported livestock, as it was done earlier, but on the rational use of our own resources. To implement ideas on import substitution in animal husbandry, it is necessary to form herds of cows with a high level of biological potential and biological value of products, as well as high efficiency of using dry matter of feed, which will contribute to the fullest realization of the genetic potential of the breed. The value of dairy products is determined by the content of all components that make up milk (fat and protein content, nonfat milk solid, dry matter, etc.). Dry matter is the basis for determining the consumption rate of all other nutrients of the feed, a high level of which ensures the intake of the necessary amount of energy and nutrients into the body of the animal, which in turn contributes to the most complete realization of the genotype. An objective assessment of the effectiveness of dry matter is given by the FCR and GFE coefficients, which are influenced by many factors, including genetic ones.
