Crossbreeding components for growth performance of the Egyptian Baladi Red rabbits crossed with the acclimatised New Zealand White

Abstract: Data were obtained on a total of 621 F1 straight-bred (337) and cross-bred (284) weaned rabbits, produced from two breeds, one exotic, New Zealand White (NZW) and the other is an Egyptian, Baladi-Red (BR) as well as their two reciprocal crosses. The experiment was carried out at Kafr-El-Sheik, Sakha Research Station, Ministry of Agriculture, Egypt. The study aimed to estimate the heterotic components of biweekly body weight (BW) and daily gain (DG) traits from weaning (at the 6th wk of age) up to marketing (at the 16th wk of age).
Mating group effect succeeded to prove significance on BW and DG traits, except at 14 wk of age for BW and 12-14 wk of age for Dg. Significant heterosis was found for DG from 6 till 12 weeks of age intervals but not for BW, where insignificant negative values are found except at weaning. Direct additive effect for BW and DG traits were not significant in favor of BR bucks except BW at 10 weeks of age and DG at 6-8, 8-10 and 14-16 weeks of age. Maternal additive effects for BW and DG were in favor of NZW breeds, positive values and significant at 8, 10 and 12 weeks of age for BW and 6-8, 8-10 and 10-12 weeks of age for DG traits.
