摘　　要：为研究扬州鹅及其杂交配套组合肌肉组织学性状对肉品质的影响,以70日龄扬州鹅(A×A)及其4个杂交配套组合(K×B、K×A、C×A和S×A)为研究对象,检测不同群体扬州鹅胸肌、腿肌的肌纤维结构和肌肉剪切力。结果表明:5个群体中,无论公母鹅,胸肌肌纤维面积、肌纤维直径极显著小于腿肌;K×B群体的肌肉组织形状(肌纤维面积、肌纤维直径、A带、H带、I带和肌节长度)在5个群体的公、母鹅中具有显著的优越性,同时肌肉嫩度也显著优于其他群体。综合而言,不同群体组织之间虽然存在显著或极显著差异,但K×B群体的组织学特性相对优于其他4个群体,在5个鹅群体中肉品质最好。This research study The slaughtering performance and meat quality were systematically investigated in this study. 70-day-old Yangzhou geese （AX A） and its 4 different crossbred combinations （KX B, KX A, CX A and SX A） were used as the objects to systematically study the muscle fiber structure and muscle shear force of chest muscle and leg muscle. The results showed that： Regardless of the male and female, chest area of muscle fiber, diameter of muscle fiber was significantly less than the leg muscle in 5 groups （P〈0. 01） ; The muscular histological characteristics of the group K X B （area of muscle fiber, diameter of muscle fiber, A belt, H, I and the sarcomere length） had significant advantages in male goose and goose of five groups, at the same time, muscle tenderness, was also the best. In summary, although dif- ferent groups had significant or extremely significant differences （P〈0. 05 or P〈0. 01）, the muscular histological char- acteristics of group KX B was relatively better than the other four groups and was the best in meat quality of the five goose groups.
