Components of litter size in gilts with different prolactin receptor genotypes.

Theriogenology - 1 Feb 2003

van Rens Birgitte T T M, Evans Gary J, van der Lende Tette

Abstract excerpt

Behavioral estrus and components of litter size at Day 35/36 of pregnancy were studied in gilts with prolactin receptor (PRLR) genotype AA (n=9), AB (n=25), and BB (n=22). This PRLR polymorphism (two alleles, A and B) has been associated with litter size, although it is not known whether the polymorphism itself causes differences in litter size or whether it is a marker for a closely linked causative gene. Estrus...
