Abstract
The genetic variations of FUT1 gene at nucleotide position 307 of its open reading frame were investigated by PCR-RFLP in a total of 245 pigs from 3 exotic pig breeds and 3 Chinese native pig breeds. Results showed that the genetic polymorphisms of the FUT1 locus were only detected in the 3 exotic pig breeds. There were 3 different genotypes and the majority were the susceptible forms including GG and AG. All Chinese native pig breeds only presented the susceptible genotype GG. Univariate analysis of variance components indicated that FUT 1 gene and the type of breeds significantly affected total number born, whereas parities did not. None of these factors significantly affected the number of liveborns.
