Role of Embryonic and Maternal Genotype on Prenatal Survival and Foetal Growth in Rabbit
Contents The aim of this work was to evaluate the influence of maternal and embryonic genotype on prenatal survival and foetal growth during pregnancy. Embryos were recovered at 48h of gestation from two different donor lines (R=46 and A=40) and transferred to nulliparous recipient does (26 R and 24...

| description | Contents The aim of this work was to evaluate the influence of maternal and embryonic genotype on prenatal survival and foetal growth during pregnancy. Embryos were recovered at 48h 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 Days 14, 24 and 30 (12, 24, and 14, respectively) to determine the number of live foetuses and the weight of live foetuses, foetal placenta and maternal placenta. A transcriptome analysis was performed to search for differences between foetal placentas at Days 14 and 24 of development. Prenatal survival at Days 14, and 24 was affected by embryonic genotype and determined by maternal genotype at Day 30. Foetal weight at Day 14 was influenced by both genotypes, being the weight higher for group A/A (0.29 +/- 0.01g vs 0.19 +/- 0.01g, for group R/R). However, both genotypes were determinant for foetal placenta weight at Day 24, while those genotypes affected maternal placenta weight at Day 30. Nevertheless, no differences in foetal placenta at transcriptome level and progesterone and IGF-I plasma levels in recipient does were found. In conclusion, results indicate that the influence of embryo and maternal genotype on the prenatal survival and growth seems to be changing over gestation. |
