Influence of weaning age (28 vs. 63 d) on quantitative and qualitative carcass traits of rabbits

Nowadays there is an increasing interest towards breeding systems, also for rabbit meat production, that are more mindful of animal welfare through an attenuation of the productive cycles intensity. These particular rearing techniques provide a delaying of the weaning age to reduce young rabbits stress. The present experiment is part of a wider research (Pinna et al., 2004; Marongiu et al., 2004) conducted in a sardinian farm in which rabbits are usually weaned at about 60 days of age. Surely this managerial choice could be considered rather questionable but from a scientific point of view could also represent the occasion to examine the productive performance of rabbits submitted to such a late weaning. The final part of the survey, regarding the carcass composition and the meat chemical-nutritional characteristics, was carried out through the comparison of two groups of rabbits weaned at 28 and at 63 days of age respectively.
