Summary: For the first time, the article highlights the issue of the efficiency of cattle breeding of a new population Bukovyna zonal type of meat polled Simmental ruminants, which is relevant in the Carpathian region of Ukraine. The results of research have showed that the growth intensity of repair heifers with the genotype (3/4Simmental Canadian + 1/16Simmental Austrian + 1/8Simmental German + 1/16Simmental American) from birth to 7 months of age prevails by 3.4% (P<0.001) their improved peers with the genotype (1/32Simmental combined + 27/32Simmental Canadian + 1/32Simmental Austrian + 3/32Simmental German) in the herd of the breeding plant State Research Farm “Chernivetske” of Bukovyna State Agricultural Experimental Station of Institute of Agriculture of the Carpathian region of NAAS. The difference is that the linear and mass dimensions in cattle of a new population with the genotype (3/4Simmental Canadian + 1/16Simmental Austrian + 1/8Simmental German + 1/16Simmental American) increase with the raise of their heredity. Their live weight increased by
15.5 kg, the height at withers – by 3.1 cm, the chest circumference – by 4.8 cm, the oblique length of
the torso and buttocks – by 1.7 and 2.1, respectively, and the overall dimensions – by 13.5 cm. Studies have shown that in terms of relative live weight gain, the repair heifers of the most productive genotype (3/4Simmental Canadian + 1/16Simmental Austrian + 1/8Simmental German + 1/16Simmental American) prevailed the heifers of the genotype (25/32Simmental Canadian + 1/16Simmental Austrian + 1/8Simmental German + 1/32Simmental American) for the period from birth to 3 months of age by 7.3% (P>0.99), from 9 to 12 months of age – by 1.2% (P<0.95), from 12 to 15 months of age – by 15.4% (P<0.95), from 15 to 18 months of age – by 17.4% (P <0.95) and from birth to 18 months of age – by 29.9% (P>0.99). Only between 9 and 12 months of age the best average indicators were reduced to 1.2% (P>0.99) and 0.9% (P<0.95).
