Abstract: The interaction between sows and reproductive proteins was studied. The genes associated with the breeding of related sows have been excavated, and GeneMANIA can be used to predict the possible interaction of genes in the related sows and their contribution to the reproductive traits of sows. The study found that 15 genes predicted that the reproductive traits could be divided into 151 small phenotypes, and these 15 genes played a role in these 151 phenotypes respectively. When predicted by 40 genes, the reproductive traits can be divided into 153 small phenotypes, and these 40 genes play a role in these 153 phenotypes, respectively.

Key words: pig, reproduction, protein interaction
