摘 要：
为优化银杏-杜仲叶固态发酵工艺条件,并研究银杏-杜仲叶复合发酵产物(FGE)对肉鸡生产性能和肠道功能的影响,选用360只健康1日龄的AA肉鸡(P>0.05),随机分为6个处理组,每组60只鸡,分为空白对照组,未发酵银杏-杜仲叶(NFGE组,分别在基础日粮中添加NFGE前期0.3%,后期0.6%),及4个FGE组(FGE1,FGE2,FGE3,FGE4,即前期分别在基础日粮中添加FGE 0.2%、0.3%、0.4%和0.5%,后期分别为0.4%、0.6%、0.8%和1.0%)。结果显示:银杏叶与杜仲叶配比2∶1,黑曲霉菌接种量2.0%,发酵温度28℃,发酵时间96 h时为固态发酵的最佳工艺条件。与对照组相比,FGE2和FGE3组的料重比(F/G)在22～42 d和1～42 d间有显著降低(P<0.05);日粮中添加FGE能够显著增加十二指肠和空肠的绒毛高度、空肠和回肠的绒毛高度与隐窝深度之比、胰腺蛋白酶、十二指肠和空肠的蛋白酶、淀粉酶和碱性磷酸酶(AKP)活性显著提高(P<0.05),同时,血清D-木糖水平显著提高(P<0.05),血清尿素氮水平显著降低(P<0.05)。结果表明:在最佳发酵工艺下获得的发酵产物总黄酮含量为2.13%,绿原酸的含量为0.50%;日粮中添加0.2%～0.5%(后期0.4%～1.0%)的FGE能够在一定程度上促进肉鸡生长发育,并改善肠道消化吸收功能。

摘 要：
In order to optimize the solid-state fermentation conditions of Ginkgo and Eucommia leaves and to study the effects of fermented Ginkgo and Eucommia leaves(FGE) on the performance and intestinal function of broilers. A total of 360 1-d-old broilers(P>0.05) were randomly allocated to 6 dietary treatment groups with 6 replications of 10 birds in each group. The groups were the control group(fed with basal diet), and the unfermented FGE group(with NMOL at 0.3% in the early stage and 0.6% in the later stage, respectively, in the diet), and the 4 FGE groups(FGE1, FGE2, FGE3 and FGE4, containing 0.2%, 0.3%, 0.4%, 0.5% FGE in the early stage and 0.4%, 0.6%, 0.8%, 1.0% FGE in the later stage, respectively, in the diet). The results showed that the optimal fermentation conditions of FGE were the ratio of Ginkgo biloba leaf to Eucommia ulmoides leaf, 2:1; and inoculation of Aspergillus Niger 2.0%, at 28 ℃ for 96 h. Compared with the control group, the FGE2 and FGE3 groups had lower F/G during the periods of 22-42 days and 1-42 days(P<0.05). Dietary FGE supplementation significantly increased the villus height of duodenum and jejunum, the ratio of villus height to crypt depth of jejunum and ileum, and also the activities of pancreatic protease, protease, amylase and AKP in duodenum and jejunum(P<0.05). However, the levels of serum D-xylose were significantly increased and SUN were significantly decreased by the supplementation( P<0. 05). These results indicated that,under the optimal fermentation conditions,the contents of total flavone and chlorogenic acid of the fermentation products were2. 13% and 0. 50%,respectively. Dietary FGE supplementation contributed to the growth and development of broilers,and improved their intestinal digestion and absorption function.
