“…In agreement with other authors (Dalle Zotte, 2002;Hernandez et al, 2006;Hulot and Ouhayoun, 1999;Khalil and Al-Saef, 2008;Zgur and Kermauner, 2005) who indicated that selection for growth rate has little effect on meat quality, the pHu and WHC were not significantly influenced by genetic origin of rabbits (Table 2). Meat colour values revealed significant differences between genotypes (P<0.01): meat derived from LP showed lower lightness (L*), higher redness (a*) and yellowness (b*) than HY.…”

“…Meat colour values revealed significant differences between genotypes (P<0.01): meat derived from LP showed lower lightness (L*), higher redness (a*) and yellowness (b*) than HY. This result suggests that local population furnished less pale meat, as confirmed by the higher C* value (P<0.01) and it was probably due to their higher slaughtering age: the more coloured meat in older animals could be a consequence of a decrease in the oxidative metabolism, correlated with the increase of glycolytic energy metabolism (Dalle Zotte, 2002;Pla, 2008;Zgur and Kermauner, 2005). As regards meat colour traits, significant differences between variances are noted for b* and C* (P<0.05) showing the highest variability in local population parameters.…”

To evaluate the effect of genotype on carcass traits and meat quality, sixty-four rabbits belonging to two genotypes (slow growing local population, LP; commercial hybrids, HY) were used. Rabbits were weaned at 35 days of age and slaughtered when they reached 2500 g of live weight, corresponding to 103 and 87 days of age for LP and HY, respectively. Comparing the slaughter traits of two genotypes, LP provided higher dressing out (59.4 vs 56.2%, P<0.01) and skin percentage (16.0 vs 14.2%, P<0.05), lower incidence of full gastrointestinal tract (18.5 vs 22.3%, P<0.01) and higher incidence of head (9.5 vs 8,9%, P<0.05) and kidneys (0.99 vs 0.86%, P<0.05) than HY. Reference carcasses from LP had greater incidence of perirenal fat (2.04 vs 1.12%; P<0.01), loin (21.5 vs 19.2%; P<0.01) and hind leg (34.4 vs 31.6%; P<0.01) than HY. Hind leg meat-to-bone ratio was significantly higher in HY than LP (4.7 vs 3.8%; P<0.01). The comparison between the variances of slaughter weight, chilled carcass weight, kidneys percentage, reference carcass weight, perirenal fat and hind leg percentage showed the greatest variability in the LP. Meat derived from LP showed lower L*, higher a*, b* and C* colour values than HY (P<0.01). In conclusion, LP showed good slaughter traits and favourable meat quality. The great variability observed in the LP could allow to improve the productive performances, however maintaining animal rusticity

Abstract:To analyse the effect of pasture availability and genotype on innate immunological status, morphological organisation of lymphoid follicles, behaviour, performance and carcass and meat characteristics, 80 growing rabbits (40 Leprino of Viterbo and 40 New Zealand White, NZW) were reared in bicellular standard cages (control) or in a wired pen, provided with an external grass pasture (pasture). Blood samples and behaviour observations (10 rabbits per group) were performed at different ages (weaning, 49 and 89 d). At the end of the trial, 10 rabbits per group were slaughtered to study meat quality/composition and vermiform appendix structure. Leprino rabbits showed higher serum lysozyme values than NZW for all ages and rearing systems. Leprino rabbits showed the highest values in caged animals (29.6 and 32.4 mg/mL, respectively at 49 and 89 d of age), while NZW animals did so in the pen (2.2 and 0.00 g/mL, respectively at 49 and 89 d of age). Haemolytic Complement Assay increased with age in Leprino (43.7 vs. 48.6 and 51.2 μg/mL, respectively for cage and pen), but decreased in NZW (68.6 vs. 25.8 and 41.1 μg/mL, respectively for cage and pen). Plasma TBARs was always higher in Leprino rabbits ( . Mortality rate of Leprino rabbits was highest in the cage system, while mortality was highest in NZW housed in the pen. Productive performance, carcass traits and fatty acid composition of meat were strongly affected by genotype and rearing system. Regarding genotype effect, Leprino showed lower daily gains (31.9 and 29.6 vs. 44.2 and 40.0 g, respectively for cage and pen system), live (2563 and 2418 vs. 2902 and 2650, respectively for cage and pen system) and carcass weights (1561 and 1465 vs. 1763 and 1580, respectively for cage and pen system). Pasture availability improved the meat nutritional quality and, in particular, the n-6/n-3 ratio was optimal and the total tocopherol content was suitable to assure a good oxidative stability.
