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).
