Evaluation of crossbreeding effects for some litter traits in crossing of Californian with Egyptian Baladi red rabbits
Abstract: A crossbreeding experiment [between Californian, CAL, and Baladi Red, BR, rabbits] was carried out during two consecutive years of production starting in September 2005 to August 2007 to estimate direct (individual) and maternal heterosis (HI & Hm), direct and maternal additive effect (GI & Gm). Also direct recombination effects (RI) were genetically evaluated for some litter traits [litter size at birth and at weaning (LSB&LSW), number born alive (NBA), litter weight at birth and at weaning (LWB & LWW) and litter weight gain and Daily litter weight gain (LWG&DLWG)]. Estimates of (HI) were positive and significant (P<0.05 or P<0.01) for all litter traits studied except LSW. Estimates of Hm were found to be positive and significant (P<0.05 or P<0.01) for LWB, LWW, LWG and DLWG. Estimates of GI and GM were significant (P<0.01) for LWB, LWW and LWG, with superiority of CAL sires and dams over BR ones. RI effects were positive in all traits and were significant (P<0.01) for LWB, LWW, LWG and DLWG.
Key words: Baladi Red rabbits, crossing, heterosis, additive effect, direct recombination effects.
