Nutritional value and environmental safety of bulls meat of the dairy direction

Abstract

The authors present the results of research, according to the comparative assessment, food and biological value of beef from the purebred bulls of the Holstein breed belonging to different lines. The genetic potential of animals had a certain impact on high-quality indicators of the resulting meat raw materials. It has been established that the maximum amount of protein in the long muscle of the back was in the bulls of the reflective line, respectively, 0.53 and 0.8% compared with the same indicator of other animal lines. Culinary and technological indicators of meat studied groups are defined. The calculation of the amino acid ski was above 100% in all experimental groups, which indicates the usefulness of the obtained meat raw materials. Intergroup differences are noted on the most optimal content of essential amino acids, which slightly affected the biological value of meat.
