摘要本试验旨在研究不同添加量的发酵饲料对1~55日龄肉鹅生长性能、血清生化指标及免疫指标的影响。采用完全随机试验设计，选取1日龄、健康的肉鹅720只，随机分为4组，每组6个重复，每个重复30只。对照组饲喂基础饲粮，试验组饲喂在基础饲粮中分别添加2.5%、5.0%和7.5%发酵饲料的试验饲粮。试验期共55 d，分为1~15日龄和16~55日龄2个阶段。结果表明：在生长性能方面，与对照组相比，3个试验组的末重、平均日增重（ADG）、平均日采食量（ADFI）和料重比（F/G）均没有显著差异（P>0.05），其中2.5%、5.0%和7.5%组末重分别提高了1.94%、1.79%和2.56%，2.5%、5.0%和7.5%组ADG分别提高了1.97%、1.82%和2.57%。在血清生化指标方面，与对照组相比，2.5%组血清中碱性磷酸酶（AKP）和酸性磷酸酶（ACP）活性以及甘油三酯（TG）含量差异不显著（P>0.05），5.0%和7.5%组的血清中AKP和ACP活性以及TG含量显著降低（P<0.05），血清AKP活性分别降低了55.48%和59.59%，血清ACP活性分别降低了37.28%和43.79%，血清TG含量分别降低了30.25%和16.67%。在血清免疫指标方面，对照组与试验组血清免疫相关指标均无显著差异（P>0.05）。综合各项指标，在1~55日龄肉鹅饲粮中添加7.5%发酵饲料的饲喂效果优于添加2.5%和5.0%发酵饲料。

Abstract：This study was designed to investigate the effects of fermented diets of different supplementation on the growth performance and serum biochemical indexes and immune indexes of meat geese at 1 to 55 days of age. A total of 720 healthy, 1-day-old meat geese were randomly divided into 4 groups with 6 replicates and 30 replicates each in a completely randomized trial design. Meat geese in the control group fed a basal diet, and those in the experimental groups fed the basal diet added with 2.5%, 5.0% and 7.5% fermented diets, respectively. The experiment lasted for 55 d, which included 2 stages of 1 to 15 days of age and 16 to 55 days of age. The results showed that compared with control group, there were no significant differences in final weight, average daily gain (ADG), average daily feed intake (ADFI) and feed/gain (F/G) in the three test groups (P>0.05), final weight in 2.5%, 5.0% and 7.5% groups increased by 1.94%, 1.79% and 2.56%, respectively; ADG in 2.5%, 5.0% and 7.5% groups increased by 1.97%, 1.82% and 2.57%, respectively. In terms of serum biochemical indexes, compared with the control group, the activities of alkaline phosphatase (AKP) and acid phosphatase (ACP) and the content of triglyceride (TG) in serum in 2.5% group were not significantly different (P>0.05). Serum AKP and ACP activities and the content of TG in 5.0% and 7.5% groups were significantly reduced (P<0.05), the activity of AKP in serum decreased by 55.48% and 59.59%, and the activity of ACP decreased by 37.28% and 43.79%, and the content of TG decreased by 30.25% and 16.67%, respectively. There was no significant difference between the control group and the test groups in serum immune indexes (P>0.05). Combined with each index, the feeding effects of adding 7.5% fermented diet in the diets of geese at 1 to 55 days of age are better than those of adding 2.5% and 5.0% fermented diets.
