Abstract
The study of skeletal peculiarities was carried out on Simmental and Limousin bull calves and their cross breeds. The control slaughter of 3 bull calves of different genotypes was carried out at 20 months of age: I – Simmental, II – Limousin, III – 1/2 Limousin x 1/2 Simmental, IV – 3/4 Limousin x 1/4 Simmental, V – 7/8 Limousin x 1/8 Simmental. The fresh axial bones were weighed on a counter balance with the accuracy up to 1 g. The purebred Simmental bull calves (I g) were superior to Limousin herdmates (II g) both in weight of the whole skeleton and in its separate parts. This weight advantage of the entire skeleton made 0.49 kg, including the total axial skeleton weight – by 0.19 kg; in the weight of the whole peripheral skeleton – by 0.3 kg.
