The article presents the results of the study of morphological and biochemical indices of blood of ewes of the 1st and 2nd grading classes bred in the West Uzbekistan region. It was established that the blood values ​​indicate that larger meat and wool ewes of the desired type and average live weight of the production group of the 2nd class differed at the morphological level. According to the structure of the morphological composition of the blood, larger animals were characterized by slightly higher indices, which indicates a higher level of energy and protein metabolism in their body.
