摘 要:为研究不同水平的膨化血粉对雏鹅消化道微环境的影响,选取300只1日龄雏鹅,随机分为3组,在日粮中分别添加1.5%、3.0%、4.5%的膨化血粉,组成3个日粮处理。分别对其胃内容物蛋白酶活性、胰腺消化酶活性、十二指肠内容物消化酶活性、盲肠微生物菌群数量进行了测定。结果表明,3种不同水平膨化血粉处理的消化酶活性依次为3.0%膨化血粉组>1.5%膨化血粉组>4.5%膨化血粉组,其中,三者胃蛋白酶的活性分别为244.60、233.20、227.40 U/g;盲肠微生物菌群测定结果表明,3.0%膨化血粉组盲肠中乳酸杆菌和双歧杆菌的数量分别为67.1×107cfu/g和51.2×107cfu/g,均高于其他2组,而大肠杆菌的数量为11.9×104cfu/g,均低于其他2组。可见,在雏鹅的基础日粮中添加3.0%膨化血粉具有较好的应用效果。To study the effect on the gastrointestinal micro-environment of green goose from different levels of expanded blood meal.Three hundreds young geese who were one day age were selected in this study,who were divided into three groups randomly,1.5%,3.0% and 4.5% expanded blood meal were added in the grain respectively.The pepsase activity of above three groups were 244.60,233.20 and 227.40U/g.The test results of microbial population numbers showed the numbers of Lactobacillus and Bifidobacteria of 3.0% expanded blood meal group were more than other two groups,but the numbers of Escherichia coli were less than other respectively.The results showed that the gronp of 3.0% expanded blood meal had the best application effect.
