    Abstract

    An association study was performed in rabbits between early embryo survival and development, and the nonconservative SNP 12944C>G located in exon 11 and the triallellic microsatellite [(GT)15T(G)5, (GT)14T(G)5, and (GT)11T(G)7)] located in the promoter region of the oviductal glycoprotein 1 (OVGP1) gene. We analyzed an F2 cross of 2 lines of rabbits divergently selected for uterine capacity. A total of 172 and 159 females were slaughtered at 48 and 72 h of gestation, respectively, to determine whether OVGP1 influences ovulation rate, fertilization rate, early embryo survival, and embryonic stage of development. The results of the SNP indicated that all genotypes showed similar early embryo survival and a similar embryonic stage of development at 48 h of gestation. However, at 72 h of gestation, the GG genotype showed greater early embryo survival than the CC genotype (0.56 embryos) and their embryos presented less embryonic development. Analysis of the microsatellite was performed to ascertain the presence or absence of the allele (GT)14T(G)5. At both stages of gestation, the (GT)14T(G)5/(GT)14T(G)5 genotype showed greater early embryo survival (0.94 and 1.54 embryos at 48 and 72 h of gestation, respectively) and less embryonic development than the homozygous genotypes without the allele (GT)14T(G)5. © 2010 American Society of Animal Science.
