Breeding to increase goats meat productivity of the Tuva Republic

The purpose of research is to study the meat productivity of goats of the Soviet wool breed of the Tuvan population and to identify effective breeding methods for increasing meat productivity. Objectives: to study the live weight, meat productivity and identify effective methods for increasing the meat productivity of goats in the conditions of the Republic of Tyva. The object of the study were goats of the Soviet wool breed of the Eilig-Khem farm in the Ulug-Khem District of the Republic of Tyva. The studies were carried out according to generally accepted methods. The selection of goats with a high live weight (56.6-61.0 kg) and the selection of the same highly productive sires with a live weight of 60.62-65.78 kg for them ensured an increase in live weight and meat productivity in the resulting offspring. The carcasses of animals obtained as a result of homogeneous selection differed from animals obtained by heterogeneous selection in terms of weight, size, and were also characterized by massiveness, well-developed muscles. The difference in pre-slaughter weight was 4.17 kg, in carcass weight - 2.84 kg, in internal fat - 0.10 kg, in blood - 0.15 kg, in slaughter weight - 2.94 kg, in slaughter yield - 3.8 absolute percent compared to animals obtained using heterogeneous selection. The difference in carcass weight and slaughter weight is highly significant.
