Abstract
In this study, we performed PCR-RFLP analysis of CAST gene using MspI restriction enzyme to evaluate genotype distribution among Edilbay sheep population (n=60). Allele M was predominant among the studied animals. M and N allele frequencies were 0.94 and 0.06, respectively. MM and MN genotypes were detected with frequencies of 0.88 and 0.12, respectively, while NN genotype was not found in the studied population.

Abstract
When enriching the diets of sheep-producers of wool and meat-wool productivity in the breeding period with the feed additive “corn Gluten” in the amount of 56 and 66 gper head per day, the content of raw protein, lysine, methionine and cystine increases; the digestibility of the main nutrients of the diets, the volume of ejaculate, sperm activity and resistance index, sperm concentration, fertilization of ewes increases.
