Control and quercetin dihydrate-supplemented (2 g/kg) feeds were fed to 32 New Zealand White rabbits (both sexes) from 5 to 12 weeks old. Slaughter weight, carcass and organ weights, meat yields and physical and proximate meat quality were determined. Quercetin increased the hindleg meat:bone ratio (P < .001) by reducing hindleg bone weight (P = .01), contrary to the current understanding of the effect of quercetin on the skeletal system. However, this and the increase in skin weight (P = .03) may have been due to the effects of quercetin on connective tissue. Sex affected spleen weight (P = .04; female > male), head weight (P < .001; male > female), reference carcass yield (P = .02, female > male) and loin pH (P = .02; male > female), without commercial implications. Other physical and chemical meat quality traits were not affected by diet or sex.
从 5 到 12 周龄,32 只新西兰白兔(雌雄各半)分别喂食对照和槲皮素二水合物补充(2g/kg)的饲料。测定屠宰体重、胴体和器官重量、肉产量以及肉的物理和近似品质。槲皮素通过降低后腿骨重量(P=.01)增加了后腿肉与骨的比例(P<.001),这与目前对槲皮素对骨骼系统的影响的认识相反。然而,这和皮肤重量的增加(P=.03)可能是由于槲皮素对结缔组织的影响。性别影响脾脏重量(P=.04;雌性>雄性)、头部重量(P<.001;雄性>雌性)、参考胴体产量(P=.02;雌性>雄性)和腰肉 pH 值(P=.02;雄性>雌性),但无商业意义。其他物理和化学肉质特性不受饮食或性别的影响。
