POLYMORPHISM IN THE POPULATION OF KARAKUL SHEEP

Abstract

The article presents the color polymorphism of the population of sheep raised in the Karatau region, and the results of their adaptation in the external environment. Intense black sheep was highest weights and the testimony of the exterior. Here, the dark brown rams ' weight and exterior indicators were low. When classifying Karakul sheep by constitutional types, among them a high proportion of sheep of the strong type was 66.7- 68.0%. And the share of sheep of the tender type is low and amounted to 8.9-16.6%.
When studying the growth dynamics of lambs depending on age, their birth weight was 4.7-5.1 kg, and at the age of 1 month-13.0 kg-14.2 kg. The weight of rams of intense black color was higher, the birth weight was 5.1 kg, the weight for 1 month was 14.2 kg. Here, high indicators of body size for certain genetic groups were observed among lambs in the offspring of rams of intense black color. They height was 41.2 cm, oblique body length -34,4 cm, breast width -10,6 cm, depth of chest -14,6 cm, winding of breast -43,9 cm, winding of trunk- 5.7 cm.
