摘　　要：选用同一牛场的荷斯坦公犊牛25头,饲喂添加不同浓度低聚果糖(FOS)的日粮,研究其对早期断奶犊牛生长性能、血液理化指标及肠黏膜形态的影响。试验结果表明:日粮中添加FOS极显著提高犊牛的体重及日增重(P<0.01);各FOS组犊牛牛血清IgG、IgA含量肠绒毛高度、固有膜厚度、血清总蛋白、血清白蛋白显著高于对照组(P<0.05);但总胆固醇含量显著降低。说明FOS能提高犊牛的生长性能,能防止早期断奶犊牛肠道萎缩、维持肠道的正常形态结构,能影响犊牛代谢,提高犊牛免疫性能;缓解断奶对犊牛的应激。Twenty-five Holstein bull calves to evaluate the effect of calf feed adding born in different physiology biochemistry index and intestinal mocosa a similar period from Chongqing Cattle Farm were used in this study, levels of fruetooligosaceharides （FOS） on performance and blood structure of early-weaned calves. The experimental results showed that FOS supplementation, had significant effect on calves body weight and the average daily gain （P 〈 0.01）, The content of serum immunoglobulin IgG and IgA the villous height, lamina propria depth of duodenum,the concentration of DNA in the small intestinal mueosa, the concentration of the total serum protein and albumin of calves were increased （P 〈 0.05）; while the concentration of total cholesterol was reduced; The results indicated that FOS could improved the earlyweaned calves＂ performance, affected the early-weaned calves＂ metabolismprevent, prevented intestinal atrophy, maintained normal intestinal morphology; strengthened calves humoral immune ability and relieved the stress of the early-weaned on the calves.
