摘要: and Implications The prolactin receptor gene was investigated as a candidate for reproduction traits in five PIC lines consisting of Large White (2), Landrace, Duroc, White/Meishan origin. Least squares means total number born (TNB) alive (NBA) were calculated each genotype addition to an analysis additive dominance effects by line. PRLR significantly associated with TNB and/or NBA three the tested. effect greater than one pig line, although clearly varied depending on background genetics Additional data is needed confirm significant seen these lines. However, observed date suggest that this test has potential be powerful tool when used conjunction traditional selection methods some
