Genome-wide analysis provides insight into the genetic diversity and adaptability of Kazakhstan local goats.

To understand the genetic structure of local goat populations in Kazakhstan, we present the first comprehensive genomic analysis using a 70 K SNP array, examining 120 samples from six regions. The populations (Kundyzdy, Darbaza, Shokpar, Ushterek, Kenes and Kosseit) are named based on their breeding regions and are referred to ecotypes. Our results present a high genetic diversity, with observed heterozygosity (Ho) ranging from 0.

Assessing runs of homozygosity reveals production traits of Kazakh sheep breeds.

Sheep breeding in Kazakhstan is one of the main local roles in animal husbandry. This article presents the results of a study of the genetic indicators of sheep breeds in Kazakhstan, in relation to their meat and wool productivity. Genetic analysis was carried out using the ROH (runs of homozygosity) method and candidate genes for various kinds of productivity traits were identified.

Genome-Wide Association Studies Revealed Several Candidate Genes of Meat Productivity in Saryarka Fat-Tailed Coarse-Wool Sheep Breed.

Background: Saryarka sheep belong to fat-tailed coarse-wool sheep breed. This breed is distinguished by increased meat productivity while being competitive in young lamb production. Live weight and body indices are relevant data for assessing sheep body constitution, which directly affects the breeding characteristics and meat productivity of animals.

Detection of genetic variations in the and genes in Kazakh meat-wool sheep.

Kazakh meat-wool sheep are of great interest because of the intrabreed multifetal type's high productivity of 140 %-160 %. Genes encoding growth differentiation factor-9 () and bone morphogenetic protein 15 () are promising candidates for studying sheep productivity, as they affect fertility in mammals, including sheep. Thus, the purpose of this study was to assess the fertility of the Kazakh meat-wool sheep breed based on and candidate genes of fecundity for the selection of animals with valuable genotypes.

Distribution of Runs of Homozygosity and Their Relationship with Candidate Genes for Productivity in Kazakh Meat-Wool Sheep Breed.

Increasing the fertility of sheep remains one of the crucial issues of modern sheep breeding. The Kazakh meat-wool sheep is an excellent breed with high meat and wool productivity and well adapted to harsh conditions. Nowadays, runs of homozygosity (ROHs) are considered a suitable approach for studying the genetic characteristics of farm animals.
