Improving the assessment of the breeding value of pigs based on the use of BLUP methods and genomic analysis

The present paper presents the preliminary results of experiments to improve the evaluation of the breeding value of sows by such qualities as multiple births in live-born piglets, the number of business piglets at weaning at 30 days of age, and the safety of the litter. The evaluation of the breeding value of sows was carried out based on the use of BLUP methods and genomic analysis. It was found that the reliability of assessing the breeding value of sows increases significantly when both factors are taken into account: the use of genotypes of candidate genes ESR and PRLR and BLUP evaluation.
