TOPIGS says its researchers have found a series of SNPs, single-nucleotide polymorphisms, that define a genetic region that may be the explanation for genetic variation in litter size and uniformity between litters of piglets.
According to the research, the difference in average litter size between pigs with the genes and without the genes is 1.2 piglets. The company says its balanced breeding program will conduct more research on SNPs over the next few months, aiming to achieve faster and more accurate genetic progress.
