The Polymorphisms of Porcine FUT I Gene and Its Association with Growth Performance

Abstract

Abstract: In order to research FUT I genecs effect to the growth performance of piglets, the polymorphisms at M307 of FUT I gene inLaiwu Black pigs, Duroc and Yorkshire were investigated and their associationswith growth performance were analyzed.The result showed that there were polymorphisms at M307 of FUT I gene in Laiwu Black pigs, Duroc and Yorkshire, and the populations were all not in a state of Hardy -Weinberg equilibrium( p< 0101) 1G allelic frequency was the most in Laiwu Black pigs, while in Duroc and Yorkshire, the A allelic frequency were the most. The three genotypes had significant effect to Duroc ( p< 0105) and Yorkshire ( p< 0101) and no significant effect to Laiwu Black pigs on weight at day 70th,which is closely related with the diarrhea and edema of weaned piglets1It was inferred that because of the difference of breeds, FUT I can be an effective candidate gene for ETEC F18 to Duroc and Yorkshire, but not an ef - fective candidate gene to Laiwu Black pigs1Further study should be done to identify and characterize putative QTL and functional gene responsible for the resistance to ETEC F18 in Laiwu Black pigs.

Key words: ETEC F18, FUT I gene, Laiwu black pigs, Duroc, Yorkshire, Growth performance
