Племенная ценность хряков крупной белой породы с различными генотипами по ДНК-маркеру ESR

The effect of genotype for estrogene receptor (ESR) in large white boars (n=39) on the reproductive traits of their daughters (n=625) in three parities was studied. The daughters of boars carrying BB genotype of ESR comparing to daughters of boars carrying AA and AB genotypes had larger litter size (+0.11 +0.58 piglets), number of piglets born alive (+0.33 +0.76 piglets) and number of piglet at weaning (+0.06 +0.30 piglets). The significant differences for alive piglet weight in fist parity were observed: the daughters of boars carrying AA genotype has on 46.2 grams higher value of this trait comparing to daughters with BB genotype (p
