Abstract. The aim of this study was the comparative evaluation of morphometric parameters of the bodies of two domestic fine-wool sheep breeds to determine the breed that has the most potential to improve meat productivity. The object of the study was sheep at the age of one year in Stavropol breed 15 heads (n=15) and breed Manychsky Merino 15 heads (n=15). In a comparative analysis of in vivo body measurements in sheep associated with meat productivity, it was found that the height at withers, height at rump, rump width, oblique body length, chest width, chest girth, metacarpus sheep breed sheep MM superior to the ST breed. It was also found that sheep breed MM superior to the sheep of ST breed muscular tissue mass and bone body, and also on 18 morphometric parameters. Such morphometric parameters as mass of the liver and spleen, length of hind foot, length of the metacarpal bone, the depth of the thighs did not differ significantly. Analysis of the morphometric parameters of the body and internal organs in sheep ST breeds and sheep breeds of MM suggests that sheep breeds of MM significantly superior to the ST rams of the breed on many of the morphometric parameters of the body and internal organs. The obtained results indicate that breed Manychsky Merino is the most promising with respect to breeding, to improve meat productivity.
