摘　　要：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)鹅群体为试验素材,测定其屠宰性能、常规肉品质和化学指标。结果表明:5个鹅群体中,屠宰率、全净膛率都分别在87.10%、67.94%以上;肌肉肉色(OD值)为0.58～1.68,且胸肌肉色均较腿肌浅;嫩度在性别间差异不显著,但腿肌的嫩度比胸肌好;K×B群体公鹅胸肌粗脂肪、S×A群体及A×A群体母鹅胸肌的水分含量均显著高于腿肌(P<0.05),A×A群体母鹅胸肌蛋白含量极显著小于腿肌(P<0.01),S×A群体公鹅腿肌的粗脂肪含量在性别间差异显著(P<0.05),其他群体的常规化学成分含量在部位和性别间差异均不显著;除C×A群体母鹅胸肌中的肌苷酸含量显著大于腿肌外,其他群体肌苷酸和硫胺素含量在部位间差异均不显著。The slaughter performance,meat quality and chemical constitutes of 70-day-old Yangzhou geese and its four different crossed combinations（K×B,K×A,C×A and S×A）were measured.The results indicated that the percentage of dressed weight was above 87.10%,percentage of eviscerated yield was above 67.94%.The value of carnation was 0.58～1.68,and all the carnation of breast muscle were ligter than leg muscle.The tenderness of leg muscle was better than breast muscle,and there was no significant difference between genders.The content of crude fat of breast muscle was significant higher than leg muscle of gander in the K×B group（P〈0.05）,the content of water of breast muscle was significant higher than leg muscle in S×A group and goose in A×A group（P〈0.05）,the content of crude protein was extensively significant lower than leg muscle of goose in A×A group（P〈0.01）,there was no significant difference in the content of chemical constitutes between parts and between genders.Except for the content of IMP of breast muscle was significant higher than that of leg muscle from goose in C×A group（P〈0.05）,the contents of IMP and the thiamine were no significant difference between two anatomical muscles in four groups.
