摘　　要：选取300只健康、活泼的28日龄豁眼鹅,公母各半,体重为1 142.68(±50.64)g,随机分为3组,分别是血粉3%组、膨化血粉3%组和鱼粉3%组,每组设5次重复,每次重复20只鹅,试验时间28 d,研究在相同营养水平条件下,等比例的血粉、膨化血粉以及鱼粉对生长鹅生长性能和盲肠微生物菌群的影响和膨化血粉替代鱼粉的可行性。结果表明:平均日增重、饲料转化率以及盲肠内容物中乳酸杆菌、双歧杆菌数量的高低顺序为鱼粉组>膨化血粉组>血粉组,鱼粉组与膨化血粉组之间差异不显著,但均显著高于血粉组(P<0.05)。结果说明膨化血粉的饲喂效果显著好于血粉,在生长鹅日粮中可以3%比例等量替代鱼粉。Three hundred 28-day-old Huoyan geese with 1 142.68（±50.64）g body weight（females∶male=1∶1） were randomly assigned into 3 groups,5 replications each group,20 geese each replication.3% blood meal,3% expanded blood meal and 3% fish meal were added to the 3 groups respictively at the same trophic level to study the effect of three different protein feed on growth performance and caecum microorganism and to investigate the feasibility if the expanded blood meal could substitute for the fish meal in growing geese diet.The results indicated that the order of average daily gain,feed conversion rate and the population of lactobacillus and bifidobacterium in caecum content was fish meal groupexpanded blood meal groupblood meal group.There was no significant difference between the fish meal group and expanded blood meal group.But they were higher than the blood meal group（P0.05）.The result of the study suggested that the feeding effect of the expanding blood meal was better than that of the blood meal,moreover expanding blood meal in the diet of growing goose can replace the same proportion of fish meal.
