Prolactin receptor gene as a genetic marker for increased litter size in animals

a technology of prolactin receptor and gene, which is applied in the field of genetic differences for reproductive efficiency among pigs, can solve the problems of low heritability of litter size, major limiting factor in the efficient production of pork, and reproductive efficiency,

Abstract

Disclosed herein are genetic markers for animal litter size, methods for identifying such markers, and methods of screening animals to determine those more likely to produce larger litters and preferably selecting those animals for future breeding purposes. The markers are based upon the presence or absence of certain polymorphisms in the prolactin receptor gene.
