ABSTRACT: Researches on check of ram-breeders to quality of breed at early age were carried out in “Sharbulak” breed complex of Kazygurtskiy region of the Southern Kazakhstan area, on sheep of breed of the South Kazakh merino. The selected 5 rams were used in the tupping of dam at the age of 7 months. Carrying out scientifically - research works on early forecasting of breeding qualities of rams of breed of the South Kazakh merino testify that on meat qualities, it means that according to the carried-out control slaughter results of the rams No. 209620, 200279 and 219683 were as subjects of the graded up of breed and the ram No. 203383 was neutral, and the ram No. 200297 was recognized as retrogressers of breed, it follows from this that further use of rams No. 200297 and 203383 is not expediently and it is subject to rejection from flock. Thus, introduction of a preliminary estimate of ram-breeders according to the control slaughter results of the breed at the age of 7 months, for 2 years earlier allows to research the best rams, and more reasonably to use them in the subsequent tupping season, at the same time to reduce charges of the rams which are neutral and retrogressers of breed.
