摘要
Ten, one year old male cattles with initial body weight of 150±l;10 kg were randomly divided into two groups and received concentrate at 14% CP (T1) and Yeast Fermented Cassava Chip (YFCC) (T2). The cows were offered the treatment concentrate at 1% BW and urea-treated rice straw was fed ad libitum. Means were compared using t-test. All animals were kept in individual pens and received free access to water. The results have revealed that replacement of YFCC on feed intake was non-significantly different, while Average Daily Gain (ADG) and digestibility of nutrients were higher (p<0.05) in cattle fed YFCC (T2) treatments than received concentrate at 14% CP (T1) (235 and 203 g day-1). In addition, the ruminal pH, ammonia-nitrogen and blood urea nitrogen concentration were significantly different (p<0.05). The concentration of volatile fatty acid was significantly different especially the concentration of propionic acid was slightly higher in cattle receiving T2 than T1. Supplementation of YFCC (T2) could improve population of bacteria and fungal zoospore, but decreased populations of Holotrich and Entodiniomorph protozoa in rumen (p<0.05). The results indicate that supplementation of Yeast-Malate Fermented Cassava Chip (YFCC) as a replacement concentrate at 14% CP could improve rumen fermentation efficiency and digestibility of nutrients in cattle.

十，一岁男性牲畜那么与初始体重为150±升;10公斤随机分成两组，并获得浓缩物在14％的CP（T 1）和酵母发酵木薯芯片（YFCC）（T 2）。牛被提供治疗浓缩物以1％的BW和尿素处理的稻草自由进食。装置采用t检验进行比较。所有动物保持在各个笔和接收的自由饮水。的结果已表明，置换YFCC对饲料摄入非显著不同，而平均日增重（ADG）和营养物质消化率较高（P 0.05）牛喂YFCC（T 2）治疗比接受集中在14％CP（T 1）（235和203克日SUP 1 / SUP）。此外，瘤胃pH值，氨氮和血液尿素氮浓度分别显著差异（p 0.05）。挥发性脂肪酸的浓度为显著不同尤其丙酸的浓度为在接收Ť2于T 1牛略高。YFCC（T 2）的补充可以改善细菌和真菌的游动孢子的群体，但在瘤胃（P 0.05）降低的Holotrich和Entodiniomorph原生动物种群。表明酵母发酵马拉特木薯芯片（YFCC）的，补充的替代浓缩在14％CP可以改善营养物质牛瘤胃发酵效率和消化率。
