Disclosed herein are genetic markers for overall pig reproductive traits, including litter size, number born alive, number weaned, weaning weight, and number of stillborns, and performance traits, including days to reach 250 lbs., average daily gain, and feed to gain conversion, methods for identifying such markers, and methods of screening pigs to determine those more or less likely to possess these favorable reproductive and performance traits and more or less likely to produce litters with offspring who also have that same genetic ability to have these desirable traits and preferably selecting those pigs for future breeding purposes. The markers are based upon the presence or absence of certain polymorphisms in the pig follistatin gene. |
