| 摘 要： | 本试验旨在研究不同添加水平黄芩对肉鸡生长性能及回盲肠微生物菌群的影响。选取健康体重相近的1日龄肉鸡500羽,随机分为5组,每组5个重复,每个重复20羽,在基础日粮中分别添加0%(空白对照组)、0.1%、0.2%、0.4%黄芩以及1.0%抗生素(阳性对照组),试验期6周,测定1～21 d、22～42 d、1～42 d的日增重、料重比、免疫器官指数和回盲肠中乳酸菌和肠杆菌数量。结果表明,1～21 d时,各处理组日增重较空白对照组均有所增加,其中处理2增加显著(P0.05);与阳性对照组相比,各处理组的胸腺指数均显著提高(P0.05);盲肠乳酸菌数量均显著高于空白对照组(P0.05),回肠中乳酸菌数量有增加趋势。22～42 d时,与空白对照组相比,各处理组的日增重、免疫器官指数及回盲肠中乳酸菌和肠杆菌数量差异均不显著(P0.05)。结论:日粮中添加黄芩在1～21 d一定程度上可以促进肉鸡生长,改善肠道微生物菌群,其中添加0.2%黄芩效果较好。

| Abstract: | The experiment was conducted to study the effect of Scutellaria baicalensis on growth performance and microflora in ileum and caecum of broilers.In the current experiment,500 broilers of 1 d were selected and divided into 5 treatments with 5 replicates of 20 broilers in each treatment.Five treatments were supplemented with 0(control),0.1%,0.2%,0.4% S.baicalensis and 1.0% antibiotics(positive control) in the basal diets,respectively.The experiment had continued for six weeks.The effects of S.baicalensis on d... |
