摘  要：
试验旨在利用人工瘤胃双外流连续培养系统,初步研究日粮中添加不同浓度(0、0.15、0.30、0.60g/L)蒺藜皂苷(GSTT)对反刍动物瘤胃发酵参数的影响。结果表明,日粮添加不同水平GSTT对瘤胃pH、总挥发性脂肪酸(TVFA)浓度无显著影响(P>0.05);随着GSTT添加水平的提高,人工瘤胃液内NH3-N浓度、乙酸摩尔比例和乙酸/丙酸比例显著降低(P<0.05),丙酸摩尔比例显著升高(P<0.05)。提示,GSTT可望作为一种潜在的反刍动物瘤胃发酵调控剂来改变瘤胃发酵模式,改善对饲料能量和蛋白质的利用效率。综合考虑,0.30g/L GSTT为较适宜添加量。

摘  要：
The objective of this study was to evaluate the effect of gross saponin from Tribulus terrestris(GSTT) on ruminal fermentation characteristics in vitro using dual-flow continuous culture system.It was concluded that adding with 0,0.15,0.30 and 0.60 g/L of GSTT had no effect on ruminal pH and the concentration of total volatile fatty acids(TVFA)(P>0.05).Molar proportion of acetate,acetate to propionate ratio as well as NH3-N concentration significantly decreased(P<0.05),molar proportion of propionate significantly increased(P<0.05) with the concentration of GSTT adding.Theses results indicated that GSTT had a potential to be used as a rumen modulator to change the fermentation patterns and improve the utilization efficiency of energy and protein.Overall,it was suitable for supplementing 0.30 g/L GSTT.
