Abstract

The article presents materials on the study of the cows’ exterior and meat productivity of Aubrac gobies in the acclimatization period of the third and sixth generation animals in the conditions of Northern Trans-Urals. It was established that as a result of 18 years of Aubrac breeding, animals were formed in the enlarged type of physique in the conditions of the Northern Trans-Urals. Cows of the sixth generation had larger measurements in shoulder height by 9.7cm, in rump - by 5.2 cm, slantwise body length - by 12.8 cm, as well as chest depth - by 5.5cm, chest width by 9.2 cm and chest girth by 10.1 cm. The highest live weight in growing gobies between 9 and 18 months was in sixth-generation animals. The indicators that characterize animals’ meat productivity increased. The slaughter weight of the sixth-generation gobies was 330 kg. It was found that by the size of the carcasses’ edible part, animals of the sixth generation were superior to the peers of previous generations. The amount of muscle tissue in the sixth-generation gobies was the highest and amounted to 243.2 kg, muscle tissue output - 77.5%.
