The 24-bp insertion of the promoter region of prolactin gene was studied for 53 Silkie fowls, 19 Japanese native chickens and 6 commercial chickens. Forty-six Silkie fowls have genotype Del/Del, 7 Silkie fowls have genotype In/Del, however no Silkie fowls have genotype In/In. On the other hand, 11, 8 and 6 birds of other chickens showed genotypes Del/Del, In/Del and In/In, respectively. The chi-squared test using 2x3 table showed the significant difference (P<0.01) of the genotype frequencies between Silkie fowls and other chickens. These results show the significant difference of the genotype frequencies for the 24-bp insertion of the promoter region of prolactin gene between Silkie fowls and other chickens.
