The influence of complex genotypes in the PRL and β-LG genes in Lacon sheep breed on cheese producing

For the first time, an analysis of distribution allele variants in PRL and β-LG genes was conducted on Russian population Lakon sheep. The research established influence polymorphism studied quantitative qualitative characteristics Adyghe cheese. data 248 sheep showed a positive correlation between BB – with protein content milk better technological qualities for cheese production. highest fat observed genotype (7.14%). curd from all genotypes characterized by optimal density good elasticity. yield obtained animals higher compared to same parameter AA , 5.5, 4.5, 3.0%, respectively, it also had 3.04, 2.90, 1.10%, respectively. practical significance lies prospect selecting carriers desirable alleles targeted selection parental pairs obtaining larger number offspring homozygous genotypes. Targeted will provide proportion herd indicators productivity parameters work carried out order Ministry Agriculture Federation No. 082-03-2023-213 dated March 07, 2023.
