A study was carried out to evaluate genetically maternal performance traits in New Zealand White (NZW) and Californian (Cal) rabbits in terms of number born alive (NBA), litter size at each of birth (LSB), 21 days (LS21) and weaning (LSW), litter weight at each of birth (LWB), 21 days (LW21), and weaning (LWW), mean bunny litter weight at each of birth (MBB), 21 day (MB21), at weaning (MBW), litter gain at each of 21 days ( LG21), weaning (LGW) and pre-weaning mortality (PWM). The studied traits were estimated from records of 956 litters in NZW and 490 litters in Cal rabbits in such evaluation. Data were separately analyzed for each breed using Mixed Model of the Least squares and Maximum Likelihood computer program (Harvey 1990) to obtain least square means for fixed effects (parity, season and year) for each breed and single-trait animal model to estimate heritability, repeatability, and permanent environmental effects for those aforementioned traits.
