影响酵母发酵马拉特木薯芯片的补充,作为对营养的牛瘤胃发酵效率和消化率更换精矿
摘要
Ten, one year old male cattles with initial body weight of 150±10 kg were randomly divided into 2 groups and received concentrate at 14% CP (T1) and Yeast-Malate Fermented Cassava Chip (YMFCC) (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 YMFCC on feed intake was non-significantly different, while Average Daily Gain (ADG) and digestibility of nutrients were higher (p<0.05) in cattle fed YMFCC (T2) treatments than received concentrate at 14% CP (T1) (235 and 203 g/d). 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 (23.9 and 17.8 mol/100 mol). Supplementation of YMFCC (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 (YMFCC) as a replacement concentrate at 14% CP could improve rumen fermentation efficiency and digestibility of nutrients in cattle.

十,一岁的男性牲畜那么初始体重为150±10 kg的随机分为2组,并获得精矿在14%CP(T1)和酵母发酵马拉特木薯芯片(YMFCC)(T2)。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YMFCC对饲料摄入非显著不同,而平均日增重(ADG)和营养物质消化率牛喂YMFCC(T2)的治疗比接受集中在14%CP(T1)(235和203克/天)均高于对照组(P 0.05)。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对收到的T2比T1(23.9和17.8摩尔/ 100摩尔)牛略高。YMFCC(T2)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(YMFCC)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。
