Application of genomics to the pork industry

Abstract

A relatively small number (less than 100) of DNA markers have been applied in swine breeding up to this point in time. Even so, these markers have been used for a range of different traits. Markers explaining variation in growth, lean percent, litter size, meat quality, susceptibility to developmental abnormalities, and even disease resistance have been identified and incorporated into breeding programs. Importantly, genomic and statistical tools have been developed to make use of the proliferation of genomic information that is now available. The ability to efficiently combine this information with quantitative genetics is the key to delivering continuing value for the swine industry. These DNA markers are analogous to a "turbocharger"- they work best with a good engine and chassis.
