Abstract:
Estrogen receptor (ESR) can regulate the synthesis of oestrogen and affect the reproduction of swine. The relationship between PvuII polymorphisms at estrogen receptor gene and litter size was analyzed in Laiwu breed and Landrace breed by candidate gene method. The results were shown that 56 bp of PvuII polymorphisms was the same as the beginning sequence of 3.7 kb of RFLP. The distribution of PvuII polymorphisms also could not prove that B gene was a superior gene,and there was no decisive effect of 3.7 kb band on litter size in pigs.
