| 摘 要： | 持续动态瘤胃发酵系统是在体外模拟瘤胃内发酵环境,用于瘤胃微生物代谢以及评定日粮营养价值等方面研究的机械装置。该装置是由一系列具有不同功能的设备组成。目前较新的人工瘤胃模拟系统主要能实现发酵环境中各发酵参数的实时监控并对发酵产物如产气量等进行准确计量,但与实体瘤胃内环境还存在一定差距。本文通过对国内外几种典型的持续动态瘤胃发酵系统的各部分结构和功能进行对比分析,比较各自的优缺点,提出了较为合理的设计方法。总之,持续动态瘤胃发酵系统的设计向着自动化方向发展,但在食糜样品的采集方法等方面还需改进。 |

| Abstract: | Continuous culture system of rumen mixed microorganisms is an instrument designed to in vitro simulate fermentation process of microbes in the rumen,in which medium is continuously added at a constant rate,and culture fluid is removed at the same rate.The instrument,consisting of different functional devices,can be used for researching nutrient metabolism of rumen microorganisms and evaluating nutritional value of rations.Until now,this kind of system can monitor the fermentation parameter and accurately measure the fermentation product like gas production,but it doesn’t equate to rumen environment.Based on comparison of advantages and disadvantages of structure designs and functional devices among several continuous culture systems in the literatures,some reasonable suggests were suggested for the instrumental design of continuous cultures for rumen microbes.In a word,the design of the continuous dynamic culture system is developed to the direction of automation,however,some aspects like the way of collecting chyme are needed to improve. |
