Effect of gravity, hormones, and functional loads on the differentiated muscle growth of heifers
Submitted by Гость (not verified) on Wed, 02/04/2026 - 22:38The present study investigates the intensity of muscle growth in various anatomical parts of carcasses in Black-and-White heifers and their crosses with Hereford and Charolais breeds. It was established that muscle growth exhibits significant variability, influenced by functional load, genetic factors, and the ontogenetic stage. The most intensive growth was observed in the abdominal musculature, where muscle mass increased by 25.97 times by 18 months of age, significantly exceeding the overall growth rate of carcass muscle mass (16.08).
