Growth and development of crossbred and purebred young goats in Tuva

The purpose of research is to study the growth and development of the first generation of crossbreeds obtained by crossing goats of the Soviet wool breed with goats of the Dagestan wool breed. Tasks: to study the live weight of young animals at birth and at 6 months of age; to determine the gain in live weight; to study the exterior features of young animals at 6 months of age. The object of the study were half- blooded young animals of the Dagestan wool breed (experimental group) and purebred offspring of the Soviet wool breed (control group). The studies were carried out according to generally accepted methods. As a result of introductory crossbreeding, crossbreeds were obtained that differ from purebred peers in high live weight in the studied periods. The average live weight of half-breed young animals at birth was3.9 kg, which is 1.5 times higher than purebred young animals, and 1.2 times higher at 6 months of age. The gains in live weight also differed significantly: absolute - higher by 2.3 kg, average daily - by 16.2 g , by height in the sacrum by 2.3, by width in makloks by 0.7, by depth of the chest by 1.4, by chest circumference by 6.9, by metacarpal circumference by 0.3 cm. that the overrun index, which reflects the development of meat forms, was 8.7% higher in crossbred young animals than in purebred ones.
