本研究以3头荷斯坦公牛为试验材料，采用3x3拉丁方设计，研究了沙拉皂苷对肉牛甲烷产量、瘤胃发酵、营养物质消化和血液代谢产物的影响。以1.5：1的比例饲喂苏丹草干草和精料混合物，每天两次。沙拉皂苷(DM的0、0.5和1%)，每天09：00和17：00h与精料混合给药。分别在早晨饲喂后0、2、5h采集瘤胃样品。瘤胃pH值呈数值下降，原生动物数量呈线性下降(P
The objective of this study was to evaluate the effects of sarsaponin on methane production, ruminal fermentation, nutrient digestion and blood metabolites using three Holstein steers in a 3x3 Latin Square design. The steers were fed Sudangrass hay plus concentrate mixture at a ratio 1.5:1 twice daily,. and sarsaponin (0, 0.5 and 1% of DM), which was given at 09:00 and 17:00 h daily by mixing with concentrate. Rumen samples were collected 0, 2, and 5 h after morning dosing. Ruminal pH was numerically decreased and numbers of protozoa were decreased linearly (p
