| 3 | In vitro Ruminal Gas Production Kinetics of Four Fodder Trees Ensiled With or Without Molasses and Urea显示文摘This study investigated if the addition of urea (U), molasses (M) or their 1:1 (v/v) mixture during ensiling increases the nutritional value of forage from four fodder trees (Prunus persica, Leucaena esculenta, Acacia farnesiana, and Prunus domestica). Forage samples of fodder trees were collected in triplicate (three individual samples of each species) and subjected to an in vitro gas production (GP) procedure. Fermentation at 24 h (GP 24), short-chain volatile fatty acids (SCFA), and microbial crude protein production (MCP), in vitro organic matter digestibility (OMD), metabolizable energy (ME) and dry matter degradability (DMD) were estimated. Forage samples were incubated for 72 h in an incubator at 39oC and the volume of GP was recorded at 2, 4, 6, 8, 10, 12, 24, 48, and 72 h of incubation using the reading pressure technique. The rumen fermentation profiles were highest for P. persica, which showed the highest (P<0.0001) DMD, ME, OMD, SCFA, GP 24 and MCP. On the other hand L. esculenta had the lowest (P<0.0001) DMD, SCFA, MCP; P. domestica had the lowest (P<0.0001) OMD. The addition of M to silage increased (P<0.0001) ME and OMD, as well as GP. However, the addition of U and the mixture of U and M reduced (P<0.0001) DMD, ME, OMD, SCFA, GY 24 and MCP. These results show that P. persica has the highest nutritive value and L. esculenta the lowest for ruminants. Additionally, the addition of M to forage from fodder trees increases rumen GP and fermentation, which may improve nutrient utilization in ruminants. | Abdelfattah Z M Salem ZHOU Chuan-she TAN Zhi-liang Miguel Mellado Moises Cipriano Salazar Mona M M Y Elghandopur Nicholas E Odongo | 2013 | Journal of Integrative Agriculture2013，12，7： | 3 |

有资料显示,小卒中或短暂性脑缺血发作(transient ischemic attack,TIA)后7 d内的复发率可高达近10%,而急性脑梗死后进展性卒中(stroke in progression,SIP)的发生率可高达30%,甚至更高。早期复发或SIP是影响患者预后的重要因素。因此,有效地降低起病7 d内卒中复发或SIP,可以改善患者的预后,具有重要的临床意义。 | ZHAO Y YANG W TAN Z 徐安定 | 2017 | 中国卒中杂志2017，12，12： | 2 |
