【摘要】：试验旨在研究添加不同浓度的竹叶黄酮对济宁百日鸡增重及部分器官指数的影响。选用1日龄济宁百日鸡200只,随机分为4个组,每组5个重复,每个重复10只;对照组饲喂基础日粮,试验组Ⅱ~Ⅳ分别在基础日粮中添加0.05%、0.25%和0.45%的竹叶黄酮,试验期4周。结果表明:与对照组比较,1周龄0.45%剂量组的肝脏指数极显著提高(P0.01)。3周龄0.45%剂量组的肝脏指数显著提高(P0.05),0.25%和0.45%剂量组的肌胃指数极显著提高(P0.01),0.05%剂量组的胸腺指数显著降低(P0.05)。4周龄0.05%剂量组肌胃指数极显著降低(P0.01),0.25%剂量组的心脏指数显著提高(P0.05),肝脏指数极显著提高(P0.01)。各试验组济宁百日鸡的周增重均有不同程度提高,4周龄0.25%剂量组显著提高(P0.05),而0.45%剂量组极显著提高(P0.01)。可见,日粮中添加一定量的竹叶黄酮能够提高济宁百日鸡早期的增重、肝脏指数、肌胃指数、心脏指数和周增重,并且不同程度降低胸腺指数。
[Abstract]:The purpose of this study was to study the effects of different concentrations of bamboo leaf flavonoids on weight gain and organ index of Jining 100 day chickens. 200 1-day-old Jining 100 day chickens were randomly divided into 4 groups, 5 replicates in each group, 10 replicates in each group, and 0. 05% and 0. 45% bamboo leaf flavonoids were added to the basal diet in the control group and the control group respectively for 4 weeks. The results showed that compared with the control group, the liver index of 0.45% group at the age of 1 week was significantly higher than that of the control group. The liver index of the 0.45% group at the dose of 0.45% at the age of 0.45% was significantly higher than that of the control group. The muscular gastric index of the 0.25% and 0.45% dose groups of P0.05% and 0.45% was significantly higher than that of the control group. The cardiac index and liver index in the group of 0. 05% P0. 05% and 0. 25% P0. 01% of P0. 05% were significantly increased, and the liver index was significantly increased in the group of 0. 05% of P0. 05 and 0. 25% of P0. 05% respectively. The weekly weight gain of Jining 100 day chickens was increased in different degree in each test group. The 0.25% dose group significantly increased P0.05N, while the 0.45% dose group significantly increased P0.01g. It can be seen that adding a certain amount of bamboo leaf flavonoids to the diet can increase the early weight gain, liver index, muscle and stomach index, heart index and weekly weight of Jining 100 day chicken, and decrease the thymus index in varying degrees.
