摘　　要：[目的]研究不同剂量野山杏总黄酮对三黄肉鸡屠宰性能的影响。[方法]采用单因素试验设计,将96羽1日龄雌性三黄肉鸡随机分为4组,每组24羽。于14日龄开始,野山杏总黄酮低、中、高剂量组肉鸡分别灌服50、100、200 mg/(kg·BW·d)的野山杏总黄酮,对照组肉鸡灌服生理盐水,试验期42 d。28、35、42日龄时每组分别选取8羽肉鸡进行屠宰试验,测定并比较相同日龄下各组肉鸡的屠宰性能指标。[结果]高剂量野山杏总黄酮可显著或极显著(P<0.05或P<0.01)提高28、35、42日龄肉鸡宰前体重,中剂量野山杏总黄酮可极显著(P<0.01)提高35日龄肉鸡宰前体重。高剂量野山杏总黄酮分别显著(P<0.05)和极显著(P<0.01)提高35日龄和42日龄肉鸡屠宰率。中、高剂量野山杏总黄酮极显著(P<0.01)提高28日龄肉鸡半净膛率。低剂量野山杏总黄酮可极显著(P<0.01)提高28日龄肉鸡全净膛率,显著(P<0.05)提高35日龄肉鸡全净膛率;中剂量野山杏总黄酮可极显著(P<0.01)提高35日龄肉鸡全净膛率;低、中、高剂量野山杏总黄酮可极显著(P<0.01)提高42日龄肉鸡全净膛率。低、中、高剂量野山杏总黄酮可显著或极显著(P<0.05或P<0.01)降低35、42日龄肉鸡皮下脂肪厚度。高剂量野山杏总黄酮可显著(P<0.05)降低28日龄肉鸡肌间脂肪宽度,极显著(P<0.01)降低35日龄肉鸡肌间脂肪宽度;低、中、高剂量野山杏总黄酮可极显著(P<0.01)降低42日龄肉鸡肌间脂肪宽度。低剂量野山杏总黄酮可显著(P<0.05)降低28、42日龄肉鸡腹脂率,中剂量野山杏总黄酮可显著(P<0.05)降低28、35、42日龄肉鸡腹脂率,高剂量野山杏总黄酮可极显著(P<0.01)降低42日龄肉鸡腹脂率。高剂量野山杏总黄酮可显著或极显著(P<0.05或P<0.01)提高35、42日龄肉鸡胸肌率,可显著或极显著(P<0.05或P<0.01)提高28、35、42日龄肉鸡腿肌率。[结论]灌服不同剂量的野山杏总黄酮能够明显改善三黄肉[Objective]This study was conducted to assess the effects of different dosages of total flavonoids from wild apricot(TFWA)on slaughter performance of Sanhuang broiler chickens.[Method]Using a single factor experimental design,a total of 961-day-old female Sanhuang broiler chickens were randomly assigned into 4 groups with 24 broilers in each group.Science the 14 days of age,broiler chickens in the low,medium and high dosage groups were administrated with 50,100 and 200 mg/(kg·BW·d)of TFWA by oral gavage,respectively,while those in the control group were given physiological saline.The experiment lasted for 42 days.At the 28,35 and 42 days of age,8 broiler chickens from each group were chosen and slaughtered,respectively,and the indexes associated with slaughter performance of the broilers with the same days of age among different groups were determined and statistically compared.[Result]High dosage of TFWA significantly or extremely significantly(P<0.05 or P<0.01)increased the pre-slaughter weights of broiler chickens aged 28,35 and 42 days,and medium dosage of TFWA extremely significantly(P<0.01)increased the pre-slaughter weights of 35-day-old broiler chickens.High dosage of TFWA significantly(P<0.05)and extremely significantly(P<0.01)improved the slaughter rate of broiler chickens aged 35 and 42 days,respectively.Medium and high dosages of TFWA extremely significantly(P<0.01)elevated the percentage of eviscerated yield with giblet of 28-day-old broiler chickens.Low dosage of TFWA extremely significantly(P<0.01)and significantly(P<0.05)increased the percentage of eviscerated yield of broiler chickens aged 28 and 35 days,respectively.Medium dosage of TFWA extremely significantly(P<0.01)boosted the percentage of eviscerated yield of 35-day-old broiler chickens.Low,medium and high dosages of TFWA extremely significantly(P<0.01)increased the percentage of eviscerated yield of 42-day-old broiler chickens.Low,medium and high dosages of TFWA significantly or extremely significantly(P<0.05 or P<0.01)reduced the subcut
