“…Most scientists believe that the productive and breeding qualities, as well as the adaptive properties of animals, are determined by the level of biochemical processes in the body [4]. Studies have proven the possibility of using protein polymorphism in selection, including whey proteins [5].…”

The article reflects the data of scientific research that can serve the practice of selection and breeding work under conditions of various forms of ownership, as well as the improvement of selection and breeding work and the technology of production of high-quality and competitive sheep products in the conditions of year-round use of the foothill-steppe and desert pastures of the south of Kazakhstan. The research of polymorphism systems of serum proteins of sheep's blood of different intra-breed types by gender and age groups revealed the presence of certain allele combinations and the ratio of transferrin and hemoglobin genotypes. It has been established that these animals have their own specific range of frequencies of occurrence of alleles and combinations of genotypes. Based on the results obtained, the possibility of using genetic blood markers in the early assessment of the productive qualities of animals has been established. As a result of scientifically based breeding methods, in the “Batai-Shu” LLP in Zhambyl region created a breeding australized herd of the South Kazakh Merino breed with a white wool yolk, a cut of washed wool of 3.1 kg with a yield of 48-50%.

“…3a, S3). Each component in this range was responsible for no more than 1% of all variation, so ADMIXTURE demonstrates high On the one hand, studies including Kazakh sheep varieties usually limited by a local context (Blackburn et al, 2011;Dossybayev et al, 2018;Mukhametzharova et al, 2018;Ozerov et al, 2008aOzerov et al, , 2008b). On the other hand, in global between breed diversity studies Kazakh breeds are not being included (Kijas et al, 2012;Meadows et al, 2007Meadows et al, , 2005 or have low representation (Hiendleder et al, 2002;Meadows et al, 2011) in global between-breed diversity studies.…”

Sheep husbandry is an important branch of agriculture in Kazakhstan. Modern agrarian and breeding science demands inclusion of molecular genetic and genomic data to supplement traditional methods. Here we used medium-scale SNP genotyping for the first time to determine the population structure of five local sheep breeds in Kazakhstan and their relation to global sheep diversity.Principal component analysis and model-based structure analysis of general population markers revealed two breed groups. The first group included Akzhayik and Kazak Fine-wool sheep and the second group had Edilbay, Saryarka and Kazakh Semi-coarse wool sheep. High heterogeneity of different populations of Akzhayik and Kazakh Semi-coarse wool sheep was observed. A neighborjoining tree comparing Kazakh sheep data with the dataset generated by the Sheep HapMap project supported a close relationship between Kazakh sheep varieties and ancient domestic sheep ancestors.

“…Currently, Kazakhstan farms more than 20 indigenous sheep breeds [ 4 ]. Each of the native sheep breeds has been studied for its phenotypic traits, and lately, studies have been published on the genetic characterization of the Kazakh indigenous sheep breeds using different molecular markers [ 4 , 5 , 6 , 7 ]. Four indigenous sheep populations (Edilbay, Kazakh fine wool, Kazakh Arkhar-Merino and Kazakh fat-tailed coarse wool) were examined using 12 STR loci, which were recommended by ISAG in 2014 and indicated all of the applied markers were high polymorphic.…”

High genetic diversity was observed in all studied sheep populations except for Kazakh Arkhar-Merino [ 4 , 6 ]. Pozharskiy et al, who investigated Kazakh sheep breeds when compared with worldwide sheep based on the Ovine SNP50 BeadChip, concluded Edilbay sheep are direct descendants of historical domestic sheep ancestors [ 5 ].…”

Lamb meat has become increasingly popular in several nations during the last few decades, especially in Kazakhstan. Due to the rising demand for lamb meat, our sheep breeders developed a new fat-tailed sheep and named the breed Baisary. Animals of the Baisary breed are characterized by a large physique, strong constitution, stretched body, deep and wide chest, medium or large-sized fat tail, long legs (height at the withers of adult rams 85–100 cm, sheep 75–90 cm), long lanceolate ears and strong hooves. Lambs of the Baisary breed surpass their peers of the original parent breeds by 15–20% in live weight at the weaning period. To characterize the genetic structure of Baisary sheep and compare it with the ancestral breeds, we genotyped 247 individuals from five sheep breeds with Ovine SNP50K. The estimated private allelic richness ranged from 0.0030 to 0.0047, with the minimum and maximum provided by the Gissar (Giss1) and Kazakh meat-wool breeds, respectively. The highest and lowest FIS values, meanwhile, were observed in the Afghan fat-tailed population and Baisary sheep, respectively. The calculated inbreeding coefficient showed that Edilbay and Baisary sheep have excess heterozygosity. According to principal components analysis, Baisary are close to Gissar populations, the Afghan fat-tailed breed and Edilbay sheep. These results were consistent with the Admixture and phylogenetic analysis. Overall, our results indicated that Baisary sheep differ genetically from their progenitors.
