“…Similarly to the present results, several authors observed that the improvement of the dressing out percentage was more expressed at a younger age (Deltoro & López 1986, Lebas et al 2001, Szendrő et al 2002 or at a lower body weight (Szendrő et al 1998) than in older and heavier rabbits. Studying rabbits of identical body weight (2.45 kg), Cabanes- Roiron & Ouhayoun (1994) found a higher dressing out percentage in older rabbits.…”

“…According to the findings of Deltoro & López (1986) and Szendrö et al (2002), the ratio of the fore part of the carcass decreases markedly especially at a very young age (up to 8-10 weeks of age), while in older rabbits either a small increase or a further (non-significant) decrease has been observed. Petersen et al (1988) reported only a minor change with the age.…”

“…In rabbits of identical body weight, Cabanes- Roiron & Ouhayoun (1994) observed a significant increase in the hind part ratio in older rabbits. According to the results of Deltoro & López (1986) and Szendrő et al (2002), the ratio of the hind part and of the hind legs within the carcass increased more at a younger age than in older rabbits. However, other authors (Rao et al 1978, Petersen et al 1988 did not observe substantial changes in that respect.…”

“…Numerous data of the literature demonstrate that the ratio of the intermediate part of the carcass increases in older rabbits (Deltoro & López 1986, Petersen et al 1988, Szendrő et al 2002. According to the present experimental results this change can be explained by the increase of body weight rather than by the advancement of age.…”

A total of 238 Pannon White growing rabbits were slaughtered at 74, 84 and 94 days of age, at an average body weight of 2.53, 2.84 and 3.15 kg, respectively. Within each age group five body weight categories were formed in such a way that the weight difference between two neighbouring groups was equally 0.3 kg. The design of the experiment permitted the separate examination of the effects exerted by age and body weight on carcass traits and on meat chemical composition of the left hind leg (HL) and that of m. Longissimus dorsi (MLD). Dressing out percentage significantly increased with the increase of age in all body weight categories, as well as with the increase of body weight. The effect of age on the ratio of the fore part of the carcass depended on the body weight: significant difference was found in lower body weight categories. The ratio of the intermediate part of the carcass was not affected by age but it increased in rabbits of higher body weight. The ratio of the hind part of the carcass increased in older animals, while it decreased in rabbits of higher body weight, and this decrease was higher in older rabbits. The ratio of the perirenal fat to reference carcass significantly decreased with age in all body weight categories, but it significantly increased in rabbits of higher body weight. With the advancement of age the moisture content of the HL increased, while that of the MLD did not change. With the increase of body weight, moisture content decreased in both the HL and in the MLD. The fat content of both HL and MLD decreased in older animals, while it increased in rabbits of higher body weight. Archiv Tierzucht 54 (2011) 4, 406-418, ISSN 0003-9438 Keywords

“…Meat quality differences due to gender depend on the slaughter age, as the differences between sexes become more evident as age gradually approaches puberty. In literature, most of the data relating to gender effect concerns hybrids selected for fast growth, and they are conflicting as at commercial slaughter age some authors observed significant gender differences on some carcass traits and on meat quality (Pla and Cervera, 1997;Pla et al, 1998), whereas others did not observe any significant difference (Deltoro and López, 1986;Piles et al, 2000;Trocino et al, 2002).…”

Meat physical quality and muscle fibre properties of rabbit meat as affected by the sire breed, season, parity order and gender in an organic production system

et al. 2016

The aim of the study was to evaluate some meat physical quality and muscle fibre properties of rabbit meat when considering 2 sire breeds (SB: Vienna Blue [VB]; Burgundy Fawn [BF]; both coloured and slow-growing breeds), several parity orders (P: 1, 2, ≥3), gender (G), and 2 slaughter seasons (SS: spring, summer) in an organic production system. The effect of storage time (ST) at frozen state (2 mo at -20°C) of Longissimus lumborum (LL) meat was also evaluated. Animals were slaughtered when they reached 2.8 kg of live weight. Then, pH and L*a*b* colour values of Biceps femoris (BF) and LL muscles, water loss and Warner-Bratzler shear force of LL and hind leg (HL) meat, and the fibre typing and enzymatic activity of LL muscle were analysed. LL meat from females showed higher b* values than males (0.04 vs. -1.25; P<0.05). Significant (P<0.05) SB×P, SB×G and P×G interactions were observed for the b* value of LL: VB and BF crossbreds presented a higher b* value when born as P≥3 and P2 respectively, VB females showed higher b* value than VB males, and P2 and P≥3 produced males with a significantly lower b* value. HL thawing losses were significantly (P<0.05) higher in rabbits slaughtered in summer than in those slaughtered in spring, whereas the opposite result was obtained for LL meat (P<0.01). Cooking loss of LL meat was significantly lower in P2 group than P≥3 group (P<0.05). The lactate dehydrogenase activity in LL muscle was higher in VB than in BF crossbreds (930 vs. 830 IU; P<0.05), albeit not supported by differences in fibre type distribution. The ST significantly (P<0.01) reduced pH, a* and b* colour values, and increased lightness of LL meat. It was concluded that the crossbreeds derived from VB and BF genotypes and farmed organically did not show remarkable sexual dimorphism, considering their elder slaughter age than rabbits reared under intensive conditions. Physical quality of meat was mainly affected by slaughter season, indicating that in the organic rearing system, specific attention needs to be paid to the farming environmental conditions.
