The article presents the materials and results of research on the zootechnical and genealogical characteristics of the stud and genealogical lines of Kazakh mutton-semifine-wool sheep and South Kazakh merinos grown in the hot conditions of the semi-deserts and sands of Moyynkum in the Zhambyl region. Sheep breeding in Kazakhstan began to focus on the production of mutton and lamb meat. In this aspect, the creation of early maturing sheep, well adapted to breeding in various geographical and climatic zones is a pressing issue and has great practical significance.
In order to purposefully improve the genetic parameters that determine the high productivity of Kazakh mutton-wool meat and wool semi-fine-wool sheep, along with the old lines, new genealogical lines with valuable productive traits were established: improved wool qualities, combined with high live weight, thick wool and prolificacy of ewes (based on the use of genetics of the Finnish Landrace sheep breed), early maturing foreign breeds such as Suffolk, Texel, Dorset, Romney Marsh, Rambouillet, Australian Merinos.
The description and characteristics of the productivity of the ancestors and founders of the rams-producers of the lines (live weight, wool yield and length, quality and fineness of wool fibers, color of suint) are given, both in the existing stud lines and new genealogical lines, in all of which selection and breeding work is carried out to maintain and improve the productive qualities of the stud lines from the leading highly productive producers used in this population.
