Abstract

Disease resistance is one of the most economically important traits affecting pork production. Genetic selection for disease resistance is challenging for the industry since disease traits are not expected to be expressed in the clean genetic nucleus, where selection is performed. Data collected after animals enter commercial farms could be used to estimate breeding values for sires of commercial sows, enabling the selection of robust sires. In this work, we showed that there is genetic variance for antibody response to common infectious diseases in pigs, and major genomic regions were identified for some of these diseases. These results support the possibility of using antibody response to select for robustness in pigs.
