摘要(Abstract)：
[目的]探讨不同饲养方式在提高肌肉品质中的作用,为优质鸡肉品质的调控提供理论依据。[方法]研究笼养、室内平养、草地散养3种饲养方式对河田鸡脂肪沉积与分配和肉质性状的影响,同时探讨肌内脂肪与肉质性状的关系。[结果]结果表明,在散养条件下,河田鸡脂肪沉积显著降低(P<0.05),其中对腹脂的沉积影响最大,肌肉剪切力、肌纤维直径显著高于笼养鸡和平养鸡(P<0.05),而pH值、滴水损失、烹饪损失、肌纤维密度显著低于笼养鸡(P<0.05)。肌内脂肪与肌肉pH值、剪切力、胸肌肌纤维直径呈负相关,而与滴水损失率、烹饪损失率、肌纤维密度和嫩度呈正相关。[结论]饲养方式对脂肪沉积与分配有显著的影响,笼养鸡的肌内脂肪、肌间脂肪、皮下脂肪、腹脂率显著高于散养鸡。
