摘　　要：【目的】分析300日龄的北京鸭Z9系、靖西大麻鸭和吉安红毛鸭3个地方品种(系)鸭胸肌和腿肌营养成分,挖掘3个品种(系)300日龄的营养价值。【方法】将同一天刚出壳的1日龄北京鸭Z9系、靖西大麻鸭和吉安红毛鸭各60只在相同饲养管理条件下饲养至300日龄后,每个品种随机抽取公、母鸭各5只进行屠宰并采集胸肌和腿肌样品,测定肌肉化学成分、氨基酸以及脂肪酸含量。【结果】吉安红毛鸭胸腿肌粗蛋白含量最高,北京鸭Z9系胸肌和腿肌的肌内脂肪和胆固醇含量最高;吉安红毛鸭胸肌氨基酸总量、必需氨基酸含量和呈味氨基酸总量最高,靖西大麻鸭腿肌氨基酸总量和呈味氨基酸总量最高,吉安红毛鸭腿肌必需氨基酸含量最高;吉安红毛鸭胸肌和腿肌的饱和脂肪酸总量最低,不饱和脂肪酸总量最高,北京鸭Z9系和吉安红毛鸭胸肌多不饱和脂肪酸含量显著高于靖西大麻鸭,吉安红毛鸭腿肌单不饱和脂肪酸含量极显著高于靖西大麻鸭,显著高于北京鸭Z9系。【结论】3个地方品种(系)鸭300日龄肌肉品质比较分析结果表明,吉安红毛鸭肌肉品质和营养价值好于北京鸭Z9系和靖西大麻鸭。【Objective】Nutritional values of breast and leg meats of Peking duck Z9 line(PD),Jingxi hemp duck(JH),and Ji’an red feather duck(JR)were analyzed and compared.【Method】Sixty newly hatched ducklings of the 3 breeds/lines were purchased on a same day and raised with same forage under identical conditions for 300 d.Five male and female adult ducks from each flock of a same breed were randomly selected and slaughtered to collect breast and leg meats for analyses on chemical composition,amino acids,and fatty acids.The measured datas were preprocessed by Excel and subjected to a oneway ANOVA analysis using the SPSS 25 software.【Result】Of all nutrients,crude protein was highest in the breast and leg meats of JR;intramuscular fat and cholesterol contents were highest in the breast and leg meats of PD;and total,essential,and flavor amino acids were highest in the JR breast meat.In leg meat,JH had the highest contents of total and flavor amino acids,while JR the essential amino acids.Among the 3 breeds,JR had the most unsaturated fatty acids but the least saturated fatty acids in its breast and leg meats;in breast meat,PD and JR had significantly higher polyunsaturated fatty acids than JH;and in leg meat,JR was extremely significantly higher on monounsaturated fatty acids than JH and significantly higher than PD.【Conclusion】The meat nutritional quality of the 3 breeds of 300-d-old local ducks varied.Overall,JR appeared to be higher in that regard than PD or JH.
