Abstract

Brazil stands out as the fourth largest producer of pig meat in the world, generating thousands of jobs, thus being an important activity for the country. However, Brazilian pig farming depend on approximately 75% of genetic material for breeding programs established abroad, as few national breeding programs persist. In order for these programs to be viable in the medium and long term, annual competitive genetic gains worldwide must be obtained. Therefore, the implementation of genomic selection becomes a key point, since the incorporation of genomic information in genetic evaluations leads to considerable gains in the accuracy of prediction of genetic values. Among the traits of importance in pig production, mortality is characterized by causing great economic losses and acting negatively on animal welfare. Thus, understanding the genetic and genomic bases and the potential of increasing genetic gains using genomic information for mortality in pigs can increase genetic progress. For this, different methodologies will be used to identify genomic regions associated with mortality and to evaluate the gains in prediction accuracy of the genetic values.
