GENOTYPICAL PECULIARITIES OF GROWTH AND DEVELOPMENT OF HEREFORD STEERS OF THE URAL TYPE
The results of assessment the weight and linear growth of Hereford steers obtained from cow-dams with different productive value are submitted in the article. It is found that steers, being descendants of various cows, were distinguished by their live weight at all the age periods in spite of the similar influence of their paratypical factors (feeding and keeping). It is pointed out that during the suckling period the live weight of young steers was greatly influenced by the mothers’ milking capacity. The steers, being the maternal progeny of elite and elite-record classes, surpassed other steers of the same age by their live weight at 24.3-42.0 kg (11.0-22.4%; P>0.999). They had also significant advantage in body length, chest circumference and height measurements.
