摘要
以罗扬鹅（L×Y）、卡扬鹅（K×Y）、浙扬鹅（Z×Y）和扬扬鹅（Y×Y）4个鹅群体为试验素材,测定其0~10周龄生长性能、10周龄屠宰性能及常规肉品质。结果表明：L×Y群体宰前活重与屠体重均显著高于K×Y群体、Z×Y群体和Y×Y群体（P〈0.05）;L×Y群体胸肉肉色显著高于K×Y群体、Z×Y群体和Y×Y群体（P〈0.05）;杂交组合鹅胸肌与腿肌剪切力均小于Y×Y群体,但差异不显著（P〉0.05）;L×Y群体腿肌pH值显著高于其他3个群体（P〈0.05）;L×Y群体胸肌蛋白质含量显著高于K×Y群体、Z×Y群体和Y×Y群体（P〈0.05）;K×Y群体胸肌脂肪含量显著高于L×Y群体、Z×Y群体和YxY群体（P〈0.05）。由此可见,这种经济杂交方法不同程度地提高了鹩的生长速度和屠宰性能。
The growth performance, slaughter performance and meat quality of 70-day-old YangYang geese （Y×Y） and its 70-day-old crossbred combination LuoYang（L×Y）, KaYang （K×Y）, ZheYang（Z×Y） group were measured. The results indicated that the live weight and carcass weight of L×Y group were significantly higher K×Y group, Z×Y group and Y×Y group （P 〈0.05）, The value of breast muscle carnation in L×Y group was higher than that of breast muscle in other 3 groups （P〈0.05）.The value of breast and leg tenderness in crossbred groups was better than that of Y×Y group （P〉0.05）. The value of leg pH in L×Y group was significant higher than that of leg muscle from other 3 groups （P〈0.05）. The contents of crude protein of breast muscle in L×Y group was higher than that of breast muscle from geese in K×Y group, Z×Y group and Y×Y group （P〈0.05）. The contents of crude fat of leg muscle in K×Y group was higher than that of the other 3 groups （P〈0.05）. The results showed that the crossed combination can improve growth performance and carcass traits to some degree.
