Isolated soybean protein (ISP) with 90.3% CP on dry matter basis was fermented in a single effluent continuous culture system with six dilution rates (D; 0.025, 0.050, 0.075, 0.100, 0.150 and 0.200/h of fermenter volume) to determine the effect of dilution rate on protein fermentation by ruminal microorganisms and microbial growth efficiency. Digestibilities of dietary dry matter (DM), organic matter (OM) and crude protein (CP) were quadratically decreased as D increased. Increasing D resulted in an increase in pH, but in a decrease in ammonia and total volatile fatty acids (VFA) concentrations of fermenter contents. Molar percentages of propionate and valerate increased, whereas the percentages of acetate and butyrate decreased in response to increasing D. High molar percentages of branched chain fatty acids indicated protein fermentation occurred. As D increased, daily microbial N production and microbial growth efficiency (MOEFF) increased significantly. A quadratic model was found to fit well the data of MOEFF as affected by D, and a maximum MOEFF, 71.4 g microbial N per kg of OM truly digested, was calculated to be achieved at 0.207/h D.

采用连续培养系统的12个发酵罐进行2次培养试验,研究瘤胃稀释率(D)对于活体外蛋白质发酵和微生物生长效率的影响。6个瘤胃稀释率分别为每小时发酵液流出量占发酵罐体积的0.025,0.050,0.075,0.100,0.150和0.200倍。以大豆提取蛋白为试验日粮,随着D的提高,饲料干物质、有机物质和粗蛋白真消化率均呈二次曲线趋势下降。提高D导致发酵液pH值提高,NH3和挥发性脂肪酸(VFA)浓度下降。每个VFA摩尔比例随D的改变而变化,并表现出蛋白质发酵特征。微生物N日产生量和微生物生长效率随D的提高而显著提高。蛋白质发酵的最大微生物生长效率为每千克可消化有机物合成微生物N71.4g,其相对应的D为0.207/h。二次曲线模型适合于描述微生物生长效率

A study was conducted using a single effluent continuous culture system to investigate the effect of dilution rate (DR) on rumen microbial fermentation and microbial growth efficiency.Two DRs,0.03 and 0.06/h of fermenter volume,were used.As DR increased,there were no significant changes(P>0.05) in digestibilities of dry matter(DM), organic matter(OM),crude protein (CP),neutral and acid detergent fiber(NDF,ADF).Increasing DR from 0.03 to 0.06/h resulted in increased fermenter pH(P<0.01) and decreased ammonia...

A study was conducted using a single effluent continuous culture system to investigate the effect of dilution rate (DR) on rumen microbial fermentation and microbial growth efficiency.Two DRs,0.03 and 0.06/h of fermenter volume,were used.As DR increased,there were no significant changes(P>0.05) in digestibilities of dry matter(DM), organic matter(OM),crude protein (CP),neutral and acid detergent fiber(NDF,ADF).Increasing DR from 0.03 to 0.06/h resulted in increased fermenter pH(P<0.01) and decreased ammonia concentration (P<0.02).Total VFA production and molar proportions of acetate,propionate and butyrate were not affected(P>0.05)by DR,suggesting that changes in DR within a proper range may not alter microbial fermentation pattern in the rumen.With increasing DR,there was no change in fermenter bacterial concentrations(P>0.10),whereas significant increases in daily bacterial production (P<0.01),and decreases in fermenter protozoal concentrations and daily protozoal production (P<0.05)were found.When DR increased form 0.03 to 0.06/h,daily microbial N production and microbial growth efficiency(grams of microbial N per kg of OM truly digested) were increased by 41.6%(P<0.001) and 51.9%(P<0.001),respectively.

采用连续培养系统的4个发酵罐进行3次连续培养试验,研究瘤胃稀释率(DR,下同)对于瘤胃微生物发酵和微生物生长效率的影响。瘤胃稀释率为每小时发酵液流出量占发酵罐体积的0.03和0.06。试验日粮唯一由大豆皮组成。随着DR的提高,饲料DM,OM,CP,NDF和ADF消化率均没有显著变化(P>0.05)。提高瘤胃DR,显著提高了微生物发酵的pH(P<0.01),降低了发酵液中NH3的浓度(P<0.02),但对挥发性脂肪酸日产生量和乙、丙、丁酸比例没有显著影响(P>0.05)。发酵液中瘤胃细菌浓度不随DR变化而变化(P>0.05),但每日细菌总量随DR提高而提高(P<0.01)。发酵液原虫浓度(P<0.001)和原虫每日总产量(P<0.05)均随DR提高而下降。当DR从0.03提高到0.06时,微生物N日产生量和微生物生长效率分别提高41.6%(P<0.001)和51.9%(P<0.001)。
