The article presents data on determining the influence of linear affiliation on the meat productivity and reproductive abilities of heifers of the Kazakh white-headed breed. It was found that the animals of the Boleslav line have PH/M-25 (father) x Boleslav RN/M-25 (mother) and Marquis 411(father) x Boleslav PH/M-25 (mother) live weight at 12 months of age was 299, 7 and 291, 2, which is 6,95-3,92% more than the average for the herd. A similar trend continues in the future, at the final stage, their live weight was: 396,9 and 372,3 or 10,5-3,7% more, respectively (P?0.999).
