THE POLYMORPHISM OF ESR AND PRLR GENES IN SOWS AND THEIR INFLUENCE ON THEIR MULTIPLE PREGNANCY AND DAIRY
In the article was shown the genetic polymorphism ESR and PRLR genes in crossbred sows (Landrace × Yorkshire) and searched links genotypes of these genes with multiple pregnancy, dairy of sows and safety of pigs.In the results of investigation had not found the mark able differences in frequency of B-allele ESR- gene in sows with different multiple pregnancy.Also was investigated the link of homozygote genotype AA of PRL- gene on dairy of sows and safety of pigs.
