“…In this study, embryonic and maternal genotype had an influence on implantation rate, with a higher number of embryos implanted from line A (embryonic genotype effect) and a higher number of embryos implanted in line R recipients (maternal genotype effect). Embryo genotype effect on survival at implantation concurs with previous studies (Barkley and Fitzgerald ; Youngs et al. ; Ernst et al.…”

The aim of this work was to study the influence of embryonic and maternal genotype of two lines of rabbits selected by growth rate (line R) and litter size at weaning (line A) on prenatal survival. Embryos were recovered at 48 h of gestation from R and A donors (39 and 35 does, respectively) and reciprocally transferred to the oviducts of recipient does to the R (n = 15) and A (n = 14) lines. Each recipient doe received six embryos from line R into one oviduct and six embryos from line A into the other. Recipient does were examined by laparoscopy to determine implantation rate on day 14 and slaughtered on day 25 of gestation to determine the number of live foetuses and the weight of foetuses and placentas. No differences were found between lines in fertilization rate and stage of embryo development at 48 h post-insemination. Implantation rate was affected by both the embryonic and maternal genotype. While embryos from donor line A had the highest implantation rate (0.78 ± 0.032 vs 0.65 ± 0.036 for line R), recipient line R had a better implantation rate (0.78 ± 0.033 vs 0.64 ± 0.036 for line A). Foetal survival was affected by the embryonic genotype. Embryos from donor line A had a higher foetal survival rate than embryos from donor line R (0.65 ± 0.036 vs 0.53 ± 0.038, respectively) but lower foetal and placenta weights. In conclusion, while embryonic genotype influenced both implantation and foetal survival rate, R embryos had the lowest rates, maternal genotype affected the implantation rate and R recipients may show a greater uterine receptivity during implantation period. Moreover, it must be observed that foetal and placenta weights were significantly affected by embryonic genotype and heavier for R line.

“…Yet the influence of embryonic and maternal genotypes on placental weight is controversial. While both genotypes had an influence on foetal and placenta weight in mouse and pig (Al-Murrani and Roberts 1978;Barkley and Fitzgerald 1990;Biensen et al 1998;Wilson et al 1998), Moc e et al (2004a) stated that foetal weight in the last term of gestation depends on the maternal genotype, and foetal-placental weight depends on the embryonic genotype in rabbit. However, recently Vicente et al (2013) showed that embryonic genotype affects foetal weight, but both embryonic and maternal genotype affect foetal-placental weight in the last term of gestation.…”

The aim of this work was to evaluate the influence of maternal and embryonic genotype on prenatal survival and fetal growth during pregnancy. Embryos were recovered at 48 h of gestation from two different donor lines (R=46 and A=40) and transferred to nulliparous recipient does (26 R and 24 A). Each recipient doe received six embryos into one oviduct from line R and six embryos form line A into the other. Laparoscopy was performed at day 14 to determine implantation rate. Recipient females were slaughter at day 14, 24 and 30 (12, 24, 14, respectively) to determine the number of live foetuses and the weight of live foetuses, fetal placenta and maternal placenta. A transcriptome analysis was performed to search for differences between fetal placentas at day 14 and 24 of development. Prenatal survival at Days 14 and 24 was affected by
