Using Genetic Markers in Breeding Sheep

The aim of this study was a comparative study of the antigenic spectrum of blood groups in young sheep, resulting in industrial crossing of ewes by North Caucasian meat-wool breed and meat breeds: Texel, Edilbay breed, Poll Dorset. Proved the feasibility and advisability of the use of genetic factors to assess and predict meat productivity of sheep. Studied allele fund by erythrocyte antigen of blood, groups and factors set specificity of its composition for sheep of different genotypes (Poll Dorset x North Caucasian meat-wool breed, Texel x North Caucasian meat-wool breed, Edilbay breed x North Caucasian meat-wool breed, North Caucasian meat-wool breed x North Caucasian meat-wool breed). Determined alleles unit (Ab, R, Da), attended with a high live weight. This allows data to recommend erythrocyte antigens to predict at an early age of the animal meat production.
