Abstract: he genetic variations at M307 of FUT1 gene in foundation colony of Sutai ETEC F18+ resistant breeding pigs (total 576 individuals) were investigated by PCR-RFLP method. The relationship between FUT1 gene and some traits of growth and development were analyzed in this study. The results showed that M307 of FUT1 gene digested by Hin6Ⅰcould be divided into three kinds of genotypes(AA, AG and GG).The genotypic frequencies of FUT1 locus were 0.235(AA), 0.609(AG) and 0.156(GG) respectively, this locus deviates from Hardy-Weinberg equilibrium(P＜0.01) in above foundation colony. The correlation between three genotypes and the performances showed that the growth and development of individuals with AA genotype were higher than those of individuals with AG and GG genotypes. Body length of pigs with genotype AA was significantly higher than that of AG and GG genotypes. The 35-days body weigh of individuals with AA genotype was significantly higher than those with GG genotype. Body height and rear quarters width of AA genotype were significantly higher than those with AG genotype. The results indicated that AA genotype at M307 of FUT1 gene had good genetic effects on disease resistance traits of PWD and PED, as well as some early productive performances. And such association could be applied in the genetic breeding practice in the near future.
