Abstract: In this study, the polymorphisms at M307 of FUTⅠ gene in Laiwu Black pigs were investigated by the way of PCRRFLP and their associations with growth performance were analyzed. The result showed that there were polymorphism at M307 of FUTⅠgene in Laiwu pigs, and the population was not in a state of HardyWeinberg equilibrium(P＜0.01). The three genotypes had no significant effect on weight of birth, weight at weaning day and weight at day 70 th to Laiwu pigs(P＞0.05). It was inferred that the resistance gene to ETEC F18 might be originated from western pig breeds, and the gene play an significant effect to the western pigs and had no effect to Laiwu Black pigs. Further study should be validated to identify and characterize putative QTL and functional gene responsible for the resistance to ETEC F18 in Laiwu Black pigs.
