Effectiveness of homogeneous and heterogeneous selection of Kazakh meat and wool sheep breed for conformational and constitutional type under conditions of the Zailiiskii Altai piedmont zone

Abstract

The author presents the results of homogeneous (broad-bodied x broad-bodied constitutional type) and heterogeneous (broad-bodied x slender-bodied) variants of selecting Kazakh meat and wool sheep breed. Broad-bodied animals have greater vitality and better adaptive qualities to conditions of their breeding zone, in connection with which they have a higher level of productivity compared to slender-bodied animals. Selection of sheep for conformational and constitutional type will allow predicting the level of productivity of animals at an early age.
