Recipient maternal genotypes improved the litter size components of a paternal line involved in a MOET programme in rabbits

An essential factor in the success of multiple ovulation and embryo transfer programmes (MOET) any species is selection recipient females. In rabbit there a notable lack studies on effects genotype postnatal growth. The aim this study was to evaluate maternal genotypes litter size components within MOET programme applied commercial paternal line that appears have exhausted its after 37 generations. experiment designed using 13 nulliparous donors from R (paternal line) produce 453 embryos, which were transferred two (A V lines) own donor (R line). Litter pre-and body mass kits evaluated. differences between genetic groups recipients estimated general linear model applying Bayesian analysis. results showed lines high capacity implant maintain pregnancy present favourable environment for development compared line. Specifically, A dams highest prenatal survival, total born number alive without growth traits. demonstrated applicability based ability improve per cycle. Therefore, allow improvement meat rabbits continue line, we recommended as routine procedure.HIGHLIGHTSMOET enhanced cycle.The could be procedure favour by increasing pressure.
