The effect of estrogen receptor genotype on litter size and placental traits at term in F2 crossbred gilts

The effect of estrogen receptor (ESR) genotype (two alleles, A and B) on litter size of 275 Large White×Meishan F2 crossbred gilts (73 AA, 126 AB and 76 BB gilts) was tested. In addition, for 63 of these gilts (18 AA, 24 AB, and 21 BB) the effect of ESR genotype on average placental traits at term w...

Description
Summary:The effect of estrogen receptor (ESR) genotype (two alleles, A and B) on litter size of 275 Large White×Meishan F2 crossbred gilts (73 AA, 126 AB and 76 BB gilts) was tested. In addition, for 63 of these gilts (18 AA, 24 AB, and 21 BB) the effect of ESR genotype on average placental traits at term was tested, since individual placental information was available for 88% of the 628 liveborn piglets. Without affecting average birth weight of the piglets, ESR genotype significantly affected litter size, i.e. AB gilts had larger litters than BB gilts ( P
