Effect of embryonic and maternal genotype on foetal growth in rabbit

ABSTRACT: The aim of this work was to evaluate the influence of maternal and embryonic genotype of two lines of rabbit selected by growth rate (line R) and litter size at weaning (line A) on foetal and placental growth. Embryos were recovered at 48 h of gestation from line R (46) and line A (40) donors 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 fetuses and the weight of live foetuses, foetal placenta and maternal placenta. To analyze endocrine levels, blood serum was collected from 14 female
