摘　　要：本试验旨在研究饲粮添加植物精油和酸化剂组合对麻黄肉鸡生长性能、免疫器官指数、肠道健康和肉品质的影响。选取630只1日龄的麻黄肉鸡(母鸡),随机分为3个组,每个组7个重复,每个重复30只。对照组饲喂基础饲粮,抗生素组在基础饲粮中添加15 mg/kg亚甲基双水杨酸杆菌肽+20 mg/kg阿维拉霉素,植物精油和酸化剂组(EOA组)在基础饲粮中添加15 g/t植物精油+250 g/t酸化剂。试验期分为4个生长阶段:1~21日龄、22~42日龄、43~63日龄和64~84日龄,共计84 d。结果表明:1)试验全期(1~84日龄),EOA组肉鸡末重相较于对照组显著提高(P<0.05);1~21日龄,EOA组肉鸡末重相较于其他2组显著降低(P<0.05),平均日增重相较于抗生素组显著降低(P<0.05);22~42日龄,EOA组料重比相较于对照组显著降低(P<0.05);43~63日龄,EOA组肉鸡末重和平均日采食量相较于抗生素组显著降低(P<0.05)。2)21日龄时,EOA组肉鸡法氏囊指数相较于对照组显著升高(P<0.05);42日龄时,EOA组肉鸡法氏囊指数相较于抗生素组显著升高(P<0.05)。3)21和42日龄时,与对照组相比,EOA组肉鸡空肠隐窝深度显著降低(P<0.05),绒毛高度/隐窝深度(V/C)值显著升高(P<0.05);且42日龄时,EOA组肉鸡空肠隐窝深度和V/C值均显著优于抗生素组(P<0.05)。4)63日龄时,与对照组相比,EOA组肉鸡胸肌剪切力显著降低(P<0.05),胸肌24 h黄度值显著升高(P<0.05);84日龄时,EOA组肉鸡胸肌蒸煮损失与其他2组相比显著降低(P<0.05);63日龄时,与对照组相比,EOA组肉鸡腿肌剪切力显著降低(P<0.05),腿肌滴水损失显著低于抗生素组(P<0.05);84日龄时,与对照组相比,EOA组肉鸡腿肌剪切力、24 h亮度值和蒸煮损失显著降低(P<0.05),腿肌45 min红度值和pH显著升高(P<0.05),腿肌45 min亮度值显著高于抗生素组(P<0.05)。综上所述,饲粮添加植物精油和酸化剂组合可以提高麻黄肉鸡生长性能,改善免疫器官指数、空肠形态和肉品质�The objective of this study was to investigate the effects of dietary plant essential oil and acidifier combination on growth performance,immune organ index,intestinal health and meat quality of Mahuang broilers.A total of 630 Mahuang female broilers of one-day-old were randomly divided into 3 groups with 7 replicates in each group and 30 broilers in each replicate.Broilers in the control group were fed a basal diet,those in the antibiotics group were fed the basal diet supplemented with 15 mg/kg bacitracin methylene disalicylate+20 mg/kg avilamycin,and those in the plant essential oil+acidifier group(EOA group)were fed the basal diet supplemented with 15 g/t plant essential oil+250 g/t acidifier,respectively.The trail lasted for 84 days and was divided into four growth stages which were 1 to 21 days of age,22 to 42 days of age,43 to 63 days of age and 64 to 84 days of age.The results showed as follows:1)during the whole trial period(1 to 84 days of age),the final body weight of broilers in EOA group was significantly higher than that in the control group(P<0.05).From 1 to 21 days of age,the final body weight of broilers in EOA group was significantly lower than that in the control group and the antibiotics group(P<0.05),and the average daily weight gain was significantly lower than that in the antibiotics group(P<0.05).From 22 to 42 days of age,compared with the control group,the feed to gain ratio in EOA group was significantly decreased(P<0.05).From 43 to 63 days of age,the final body weight and the average daily feed intake of broilers in EOA group were significantly lower than that in the antibiotics group(P<0.05).2)At 21 days of age,the bursa of Fabricius index of broilers in EOA group was significantly higher than that in the control group(P<0.05).At 42 days of age,the bursa of Fabricius index of broilers in EOA group was significantly higher than that in the antibiotics group(P<0.05).3)At 21 and 42 days of age,compared with the control group,the crypt depth in jejunum of broilers in EOA group was signific
