PROLACTIN RECEPTOR GENE AS A GENETIC MARKER OF INCREASE IN AMOUNT OF LITTER OF PIGS

摘要

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