Abstract
The paper presents the study of peculiarities of the muscle development of the carcasses of Simmental, Kazakh Whiteheaded heifers and their cross breeds of the I generation. The control slaughter of 3 heifers of different genotypes was carried out at 18 months of age: I – Simmental, II – Kazakh Whiteheaded, III – 1/2 Kazakh Whiteheaded x 1/2 Simmental. To evaluate the development of a set of muscles and individual muscles, left semi–carcasses were prepared along the anatomical regions. The paper presents the analysis of the set of muscles in relation with their joints and topographic location. The development of muscles is described in terms of the absolute weight of individual muscles and the muscle sets. The paper states the advantage of crossbred heifers over their herdmates in the development of spinal muscles by 6.30–33.07 %, the weight of shoulder muscles – by 5.96–11.29 %, the entire thoracic limb – by 5.97–5.65 %, the weight of muscles of the entire pelvic girdle – by 22.13–17.19 %.
