摘　　要：本试验采用人工瘤胃体外产气法研究体外条件下日粮中添加果寡糖(FOS)制剂对水牛瘤胃发酵功能的影响。结果显示:与对照组比较,0.4%、0.8%、1.2%、1.6%和2.0%FOS组日粮可消化有机物分别提高0.84%、2.05%、2.06%、2.11%和1.34%,且差异均显著(P<0.05);代谢能分别提高1.45%、3.63%、3.63%、3.63%和2.32%,且差异均显著(P<0.05);培养液中微生物蛋白分别提高42.65%(P<0.05)、37.75%(P<0.05)、53.92%(P<0.05)、52.94%(P<0.05)和13.24%(P>0.05);挥发性脂肪酸分别提高20.9%、14.82%、18.97%、16.4%和14.58%,且差异均显著(P<0.05)。日粮添加FOS可以显著降低培养液中氨态氮含量(P<0.05),但对pH值无显著性影响(P>0.05)。综上所述,日粮中添加FOS可改善瘤胃发酵功能,且以1.6%的添加量效果最优。The experiment was conducted to investigate the effect of dietary fructooligosaccharides （FOS） on rumen fermentation functions of water buffalo using gas production of artificial rumen in vitro. The dietary level of FOS was 0% （ control）, 0. 4%, 0. 8%, 1.2%, 1.6% and 2.0% of treatments, respectively. The results showed that the dietary digestible organic matter was increased significantly （P〈0. 05） by 0. 84%, 2. 05%, 2. 06%, 2. 11% and 1.34% ; metabolic energy increased significantly （P〈O. 05） by 1.45%, 3.63%, 3.63%, 3.63% and 2. 32% ; microbial crude protein production in the incubation fluids increased by 42. 65% （P〈0. 05）, 37. 75% （P〈0. 05）, 53. 92% （P〈0. 05）, 52. 94% （P〈0. 05） and 13.24% （P〉0. 05） ; and volatile fatty acids increased significantly （P〈O. 05） by 20. 9%, 14. 82%, 18. 97%, 16.4% and 14. 58% in 0. 4%, 0. 8% , 1.2% , 1.6% and 2.0% FOS groups compared with the control group. Dietary FOS could reduce ammonia nitrogen contents in the incubation fluids but not affect pH of the incubation fluids among the groups. Together, dieta- ry FOS could improve rumen fermentation functions in the water buffalo, and dietary supplementation with 1.6% FOS was recommended in the present experiment.
