Summary: It has been found that the growth rate in this type of repair heifers from birth to 7 months of age in the genotype Simmental Canadian3/4 + Simmental Austrian1/16 Simmental German1/8 + Simmental American1/16 is higher; they reliably predominate by 3.4% (P<0.001) their improved peers of the genotype Simmental Combined1/32 Simmental Canadian27/32 Simmental Austrian1/32 Simmental German3/32 in the herd of the State Research Farm «Chernivetske». It has been determined that a correlation in repair heifers with the final genotype Simmental Canadian3/4 Simmental Austrian1/16 + Simmental German1/8 + Simmental American1/16 between the live weight during the period of rearing was low and negative: at birth r=-0.13 (P>0.095); at 7 months of age r=-0.02 and at 12 months of age r=-0.05 (P>0.095). The studies have determined that the linear and mass dimensions of a new population Simmental cattle increase with the raise of their heredity in the genotype Simmental Canadian3/4 Simmental Austrian1/16 + Simmental German1/8 + Simmental American1/16. 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.
It has been found that the growth rate in the repair heifers of meat-based polled Simmental cattle from birth to 7 months of age in a new productive genotype Simmental Canadian3/4 Simmental Austrian1/16 + Simmental
German1/8 + Simmental American1/16 is 15.7%; they reliably predominate by 3.4% (P<0.001) their improved peers of the genotype Simmental Canadian25/32 + Simmental Austrian1/16 + Simmental German1/8 + Simmental American1/
