The aim of the study was to examine the effects of genotype (Pannon Large × Pannon Ka/Large/or Hungarian Giant × Pannon Ka/Hung), housing system (Cage or small Pen) and hay supplementation (Pellet without or with Hay/P+Hay/) on carcass and meat (Longissimus dorsi/LD/ and hind leg/HL/) quality of growing rabbits. Large rabbits showed higher carcass weights, as well as higher fatness and meatiness compared to Hung rabbits. Caged rabbits were heavier, with higher prevalence of the mid part of the carcass, and showed higher fatness and lower meat toughness than Penned rabbits. Caged rabbits meat was richer in MUFA, but poorer in PUFA and Σ n-6 FA. Hay supplementation impaired carcass weight, carcass fatness, L* and a* color, and lipids content. P+Hay increased the HL meat content of C18:3 n-6 and C20:5 n-3 FA. Overall results offer further information on how alternative breeds, housing systems and feeding strategies can affect carcass traits and meat quality.
本研究的目的是考察基因型（潘农大型兔×潘农卡型/大型兔/或匈牙利巨型兔×潘农卡型/匈型兔）、饲养系统（笼养或小围栏饲养）和干草补充（无干草或有干草的颗粒料/颗粒料+干草/）对生长兔胴体和肉（背最长肌/LD/和后腿/HL/）品质的影响。与匈牙利兔相比，大型兔的胴体重更高，脂肪含量和肉质也更高。笼养兔体重更重，胴体中部比例更高，与围栏饲养的兔子相比，脂肪含量更高，肉的韧性更低。笼养兔的肉中MUFA含量更高，但PUFA和Σn-6 FA含量更低。补充干草会降低胴体重、胴体脂肪含量、L和a颜色以及脂质含量。颗粒料+干草增加了后腿肉中C18:3 n-6和C20:5 n-3 FA的含量。总体结果为替代品种、饲养系统和喂养策略如何影响胴体性状和肉品质提供了更多信息。
