| 摘 要： | 随机选取60只健康无病的300日龄雷州黑羽鸭,公、母各半,进行屠宰试验及肉品质分析。结果表明,公鸭全净膛率和瘦肉率显著高于母鸭(P<0.05);母鸭腹脂率和皮脂率极显著高于公鸭(P<0.01),而胸肌率却极显著低于公鸭(P<0.01);公、母鸭胸肌肉色(L、a、b值)、腿肌蒸煮损失率和胸肌嫩度均存在极显著差异(P<0.01);母鸭胸肌脂肪含量显著高于公鸭(P<0.05),胸肌和腿肌粗蛋白质含量极显著高于公鸭(P<0.01)。提示,雷州黑鸭屠宰率和全净膛率都较高,母鸭肉质和肌肉营养成分高于公鸭,胸肌优于腿肌。

| Abstract: | Randomly selected healthy disease-free sixty 300 days of age Leizhou Black ducks, male and female half-and-half, carried on a slaughter test. The results showed that the whole net carcass rate and lean percentage of male duck were significantly higher than female(P<0.05), the percentage of abdominal fat and subcutaneous fat percentage of female duck were extremely significantly higher than male(P<0.01), but its breast muscle percentage was extremely significantly lower than male(P<0.01), the meat color (L, a, b), cooking lose rate of thigh muscle and tenderness of breast muscle in male and female were all extremely significantly different(P<0.01), the crude protein content of thigh and breast muscle in female duck were extremely significantly higher than male(P<0.01), the fat of breast in female was significantly higher than male(P<0.05). The results showed that Leizhou Black ducks had higher slaughter rate and whole net carcass rate. The meat quality and nutrient content of muscle in female were higher than male, the breast muscle was better than thigh. |
