摘　　要：选用体重(2.36±0.01)kg的樱桃谷肉鸭108只,随机分成3个组。对照组饲喂基础日粮,试验Ⅰ组饲喂"基础日粮+250 mg/kg复合肉质改进剂",试验Ⅱ组饲喂"基础日粮+500 mg/kg复合肉质改进剂",正试期为15 d。研究酵母硒和茶多酚配伍的复合肉质改进剂对育成鸭屠宰性能、脏器系数和肌肉成分的影响。结果表明:(1)在肉鸭饲料中添加250 mg/kg复合肉质改进剂可显著降低肉鸭的腹脂率(P<0.05),并有提高肉鸭半净膛率和肌内总脂肪含量的趋势。(2)在肉鸭饲料中添加500 mg/kg复合肉质改进剂可显著提高肌肉中水分含量和肉鸭的腿肌率(P<0.05)。(3)添加复合肉质改进剂对肉鸭的脾脏系数、胸腺系数、法氏囊系数和肾脏系数均无显著影响(P>0.05);但添加250 mg/kg复合肉质改进剂可提高肉鸭的肝脏系数(P<0.05)。The study was conducted to investigate the effects of the compound meat quality ameliorant on carcass traits, organ coefficient and muscle composition of meat ducks. 108 cherry valley ducks with body weight of 2.36±0.01 kg were allotted to three groups in a randomized complete block design. The control group received the basal diets. The experiment group Ⅰ and Ⅱ were fed on ＂the basal diets ＋ 250 mg/kg compound meat quality ameliorant＂ and ＂the basal diets ＋ 500 mg/kg compound meat quality ameliorant＂ respectively. The whole feeding experiment lasted for 15 days to study the effects of compound meat quality ameliorant containing yeast selenium and tea polyphenol on carcass traits, organ coefficient and muscle composition. The results showed： （ 1 ） Adding 250 mg/kg compound meat quality ameliorant to duck feeds could significantly decease the percentage of abdominal fat （P 〈 0.05 ） and trended to improve the half net carcass percentage and reduce the fat content in muscle （0.05 〈 P 〈 0. 1 ）. （ 2 ） Adding 500 mg/kg compound meat quality ameliorant to duck feeds could significantly improve the percentage of leg muscle and the content of moisture in muscle （P 〈0.05）. （3） Adding 500 mg/kg compound meat quality ameliorant did not significantly improve the spleen coefficient, thymus coefficient, bursal coefficient and kidney coefficient. However, adding 2.50 mg/kg compound meat quality ameliorant to duck feeds could significantly improve the liver coefficient （ P 〈 0.05 ）.
