摘要: The prolactin receptor (PRLR) gene was studied as a candidate gene for the high prolificacy of Jining Grey goats. Polymorphisms in intron 1 and intron 2 of PRLR gene were detected in high prolificacy (Jining Grey) and low prolificacy (Boer, Wendeng dairy, Liaoning Cashmere and Beijing) native goats using PCR-SSCP. For intron 1, five genotypes (AA, AH, AK, HH and HK) were identified in Jining Grey goats, and two (AA and AK) in the other four breeds. The Jining Grey does of genotype HH, HK, AH and AK delivered by 0.65, 0.62, 0.59 and 0.57 more kids (P<0.01) than those of genotype AA, respectively. For intron 2, three genotypes (CC, CD and DD) were detected in Boer goats, and two (CC and CD) in the other four breeds. The Jining Grey does of genotype CD delivered by 0.55 (P<0.01) more kids than those of genotype CC.
