Genetic trend in selection for litter weight in two maternal lines of rabbits in Egypt.

Abstract: An analysis was carried out to evaluate the results of the selection program of a new synthetic maternal line of Egyptian APRI rabbits and the Spanish V line. The selection criterion was litter weaning weight in both lines based on Best Linear Unbiased Prediction (BLUP) estimations under a repeatability animal model. The studied traits were: litter birth weight, litter weaning weight (at 28 d) and pre-weaning litter gain. Heritability estimates were generally low (0.09 to 0.11) and comparable in both lines.

“…One hundred male APRI Egyptian line rabbits (Red Baldi x V‐line) selected for litter weight at weaning (Abou Khadiga, Youssef, Saleh, Nofal, & Baselga, 2010), weaned at five weeks of age and averaged body weight (BW) of 627.11 ± 2.510 g, were divided into five experimental treatments according to BW, 20 in each treatment. Rabbits in the control were fed a basal diet (BD) without supplementation, while those in treatments (2,3,4 and 5) were fed BD containing native CUR at levels of 25 and 50 mg or CURNPs at levels of 2.5 and 5 mg per kg respectively.…”

“…Ferraz et al, (1992) reported that average estimates of PBV were not regressed on year because the variation in changes from year to year might be due to some monitor effects such as changes in management or disease out breaks. Abou Khadiga et al, (2010) reported that the genetic trends were also estimated using mixed model methodology which were significant and comparable (34.2 and 32.5 g) for the selected trait (litter weaning weight) in APRI and V lines, respectively LG2…”
