日粮中添加果寡糖对水牛瘤胃液体外发酵功能的影响
Effect of dietary fructooligosaccharides on rumen fermentation functions of water buffalo in vitro
摘要
Abstract
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<0. 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<0. 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, dietary FOS could improve rumen fermentation functions in the water buffalo, and dietary supplementation with 1. 6% FOS was recommended in the present experiment.关键词
