| 摘 要： | 为考察生理应激对肉仔鸡胴体品质及肌肉品质的影响,选用108只1周龄肉仔鸡均分为对照组和皮质酮组,分别饲喂基础日粮和在基础日粮中添加30mg/kg日粮的皮质酮。21日龄时,测定肉仔鸡血液皮质酮含量;42日龄时,测定胴体和肌肉品质。结果表明:皮质酮组肉仔鸡血液皮质酮含量显著高于对照组(P<0.05)。皮质酮组肉仔鸡胸肌率、腿肌率、胸肌纤维面积、胸肌滴水损失率及胸肌脂肪含量分别比对照组低25.74%、10.47%、14.75、24.08%和42.86%,均差异显著(P<0.05)。皮质酮组肉仔鸡腹脂率、腿肌pH及胸肌中蛋白脂肪比分别比对照组高34.75%、6.65%和58.57%,均差异显著(P<0.05)。2处理间胸肌pH及剪切力,腿肌滴水损失率及剪切力,胸肌蛋白含量均无显著差异(P>0.05)。结果提示,皮质酮应激显著降低肉仔鸡胸肌率、腿肌率、胸肌滴水损失率和胸肌中脂肪含量,显著提高了肉仔鸡的腹脂率、腿肌pH及胸肌中蛋白脂肪比。

| Abstract: | The effect of stress mimicked by corticosterone administration on carcass quality and meat quality of broiler chickens was investigated in this study.One hundred and eight 7-d broiler chickens were equally divided into control group(CTRL)and experimental group(CORT),and were fed basal diet or basal diet plus of CORT 30 mg /kg diet,respectively.At 21 days of age,sera corticosterone level of broiler chickens was determined.At 42 days of age,carcass quality and meat quality were assayed.The results showed that... |
