This study aimed to investigate the effects of feeding dried bergamot pulp to rabbits on animal performance and meat quality. Thirty rabbits were assigned to two groups (balanced for body weight, 804.4 ± 2.35 g) and fed individually for 60 days a basal diet (control) or the basal diet in which part of the cereals was replaced with 10% of dried bergamot pulp (DBP). There were no effects of DBP on growth performance, carcass yield, or the crude protein and ether extract composition of meat. The concentrations of α-linolenic acid (C18:3 n-3) and eicosapentaenoic acid (C20:5 n-3) increased in the muscle ( < 0.01 and = 0.021, respectively) after integrating dried bergamot pulp into the diet, leading to higher levels of total of ω-3 fatty acids ( < 0.01) compared to the control treatment. The inclusion of dried bergamot pulp improved the oxidative stability in meat ( < 0.001), where TBARS values were lower after 4 and 7 days of refrigerated storage ( < 0.001) in the DBP group than in the control group. Finally, feeding dried bergamot pulp to rabbits improves meat quality without negatively influencing growth performance.
本研究旨在调查给兔子喂食干佛手柑果肉对动物生产性能和肉质的影响。将30只兔子分为两组（体重均衡，804.4±2.35克），分别单独喂食基础日粮（对照组）或用10%干佛手柑果肉（DBP）替代部分谷物的基础日粮60天。DBP对生长性能、胴体产量或肉的粗蛋白和乙醚提取物组成没有影响。将干佛手柑果肉添加到日粮中后，肌肉中α-亚麻酸（C18:3 n-3）和二十碳五烯酸（C20:5 n-3）的浓度分别增加（分别为<0.01和=0.021），导致ω-3脂肪酸总量水平高于对照组（<0.01）。添加干佛手柑果肉提高了肉的氧化稳定性（<0.001），DBP组冷藏储存4天和7天后的硫代巴比妥酸反应物（TBARS）值低于对照组（<0.001）。最后，给兔子喂食干佛手柑果肉可改善肉质，且不会对生长性能产生负面影响。
