In: Agricultural Research Journal, Suez Canal University 2003 v.2Summary: A total of 591 FI straight-bred (314) and cross-bred (277) weaning rabbits, produ<:ed from two breeds, one exotic, New-Zealand White (NZW) and a local one, Baladi-Red (BR) as well as their reciprocal crosses. The study aimed at the evaluation of the crossbreeding effects (i.e. Ariditive Direct and Maternal) and heterotic effect of biweekly progeny body (EL) and transverse chest length (CL) measures from (weaning) at 6 weeks up to 12 weeks of age, as well as the estimation of the /lon-genetic factors affecting these traits. Tests ofsignificance revealed that month ofbirth (MOB) succeeded to prove significance at all ages studied except at 6 week age for BL and CL traits. Significance also was detected for bleeding group (BG) on BL and CL traits except at 12'" week of age for CL trait. Feed type affected BL and CL insignificantly at all agesucept that at 8 weeks of age for BL traits. Parity affected signifi~(/ll1ly BL trait at all age studied except at 10 weeks of age, while failed to prove any significant effect/ilt CL trait. Sex affected BL and CL insignificantly at all ages except at 6" week ofage for BL traits.
