Assessment of protein, nitrogen and lipid metabolism by blood analysis of the interspecific hybrides of sheep and argali of different generations and gender-age groups

Interspecific hybridization of domestic sheep (ovis aries) with wild relatives, in particular argali (ovis ammon), is a promising area of agricultural science and practice. The aim of this work was to study the differences in the biochemical composition of blood serum in ewes and young sheep of interspecies hybrids of sheep and argali and in purebred Romanov sheep due to gender and age specific characteristics. In the group of Romanov female lambs, the concentration of total protein and globulins was higher than in animals of the second and third generation (P
