【摘要】：为探讨银杏叶发酵物(FGBL)在肉鸡饲料中的耐受剂量,选择1日龄的爱拔益加肉鸡400只,随机分为4组(每组10重复,每个重复10只),对照组(饲喂基础日粮),FGBL1、FGBL2和FGBL3组(分别饲喂添加3.5、17.5及35.0 g/kg银杏叶发酵物的试验日粮),试验期42 d,分为前期(1~21 d)和后期(22~42 d)。结果显示:FGBL1、FGBL2组显著降低了试验前期的料重比(P0.05),FGBL3组显著提高了试验后期和全期的料重比(P0.05);试验前期,FGBL1、FGBL2组的尿素氮含量显著低于对照组(P0.05),FGBL3组的丙氨酸转氨酶活性显著高于其他各组(P0.05);试验后期,3个试验组的总蛋白和白蛋白含量显著高于对照组(P0.05)。综上所述,日粮添加35.0 g/kg的银杏叶发酵物可对肉鸡生产性能造成不利影响并导致肝脏功能障碍,应用时应严格控制其剂量。
[Abstract]:In order to study the tolerance dose of Ginkgo biloba leaf ferment (FGBL) in broiler feed, 400 1-day-old Ebor plus broiler chickens were randomly divided into 4 groups (10 replicates in each group). The control group (fed with basal diet FGBL1 / FGBL2 and FGBL3 group) (fed trial diet supplemented with 3.5g / kg and 35.0 g / kg Ginkgo biloba leaf fermentations for 42 days respectively, divided into two groups: 1 / 21 d) and 2242 d / L respectively, the results showed that the FGBL1 / FGBL2 group was significantly lower than that of the control group (FGBL1 + FGBL2 group). The content of urea nitrogen in the FGBL2 group was significantly lower than that in the control group (P0.05 / FGBL3), and the activity of alanine aminotransferase in the FGBL1 / FGBL2 group was significantly higher than that in the other groups after the experiment. The contents of total protein and albumin in the three experimental groups were significantly higher than those in the control group (P 0.05). Diet supplemented with 35.0 g / kg Ginkgo biloba fermentation could adversely affect the performance of broilers and lead to liver dysfunction. The dosage of Ginkgo biloba ferment should be strictly controlled.
