Evaluation of the slaughter indicators of the Edilbaevsky sheep breed depending on the milk productivity of sheep

Relevance. Increasing the milk productivity of ewes is an important factor for improving the meat qualities of the offspring. The study of the influence of the milk productivity of ewes on the results of the control slaughter of rams of the Edilbaev breed, as well as the morphological and chemical composition of lamb, will allow optimizing the technology of growing and fattening young animals to obtain high-quality meat.

Methods. A scientific and economic experiment was carried out. The material for the experiment was sheep at the ages of 4 and 7 months. 3 groups of sheep were formed, obtained from abundant dairy queens with milk productivity per lactation (120 days) — 89.55 liters (group I of sheep), medium-dairy — 71.6 liters (group II), low-dairy — 48.4 liters (group III). To conduct the experiment, in accordance with generally accepted methods, young animals were selected according to the principle of analogues, taking into account gender, age, type of birth (males), and body weight.

Results. The results obtained indicate that an increase in the milk productivity of ewes leads to an improvement in the meat qualities of rams of the Edilbaev breed. Lambs born from ewes with high milk productivity have higher slaughter weight, slaughter yield and meat quality compared to rams born from ewes with lower milk productivity. These data can be used to develop optimal technologies for growing and fattening young animals to produce high-quality meat.
