Abstract

The study of the biological and economic characteristics of various sheep breeds shows that within each of them there are animals that are heterogeneous in productivity, morphological and physiological characteristics, and constitute intra-breed types. The presence within the breed of several different constitutional-productive types, each of which has a number of valuable features, enriches the breed as a whole, while maintaining valuable biological properties for the entire breed.
The aim of this work is to identify intra-breed exterior–constitutional productive types of Saryarka sheep and study their productivity.
The article presents the results of studying the productivity of the Saryarka breed of sheep of various exterior-constitutional types.
It was found that broad-bodied rams exceeded narrow-bodied animals in live weight and wool shearing by 8.1 and 14.2%, and ewes by 8.8 and 19.0%, respectively.
Visual determination of the exterior-constitutional types of lambs makes it possible to predict the level of productivity of Zhanaarka sheep at an early age - directly when they are beaten off from their mothers, which in turn increases the accuracy of the assessment of animals by genotype. This is one of the simplest and most affordable phenotypic methods for selecting animals in a production environment. It allows to reduce the interval between the next selection in generations and to provide for the costs of raising different groups of young animals, considering their breeding and economic value.
