| 摘 要： | 试验对20只宣城麻黄鸡在放养和笼养条件下腿部肌肉品质进行了测定,结果表明：（1）笼养组腿肌亮度（L）、黄度（b）分别较放养组高4.23%和32.05%,差异显著（P〈0.05）;蒸煮损失、硬度、黏性和咀嚼性分别较比放养组高20.96%、44.38%、35.72%和33.50%,差异极显著（P〈0.01）;而pH24、红度（a）、弹性、粘聚性和肌纤维直径,两组差异不显著（P〉0.05）。（2）笼养状态下,腿肌肌纤维直径与弹性、咀嚼性相关性均为显著正相关（P〈0.05）,与L为显著负相关（P〈0.05）;其它肉质指标间均为不显著相关（P〉0.05）;放养状态下,腿肌肌纤维直径与弹性、咀嚼性、L相关性均为不显著正相关（P〉0.05）,而与蒸煮损失相关性为极显著正相关（P〈0.01）,与pH24极显著负相关（P〈0.01）;L与蒸煮损失为极显著正相关（P〈0.01）,b与弹性为显著正相关（P〈0.05）。其它肉质指标间也均为不显著相关（P〉0.05）。

| Abstract: | Twenty Xuanhuang spotted-brown chickens reared in coops and holt were selected to determine the meat quality.The resulted showed:(1)Lightness(L) and Yellowness(b) of the thigh muscle of chickens reared in holts are 4.23% and 32.05% higher than that of in coops with a significant difference(P<0.05);Cooking loss(CL),hardness,gumminess and chewiness of the chickens reared in holts are 20.96%,44.38%,35.72% and 33.50% higher than that of in coops with a extreme deference(P<0.01);pH24,a,springiness,cohesiveness a... |
