为探讨添加双乙酸钠和糖蜜对以水稻(Oryza sativa)秸秆、玉米(Zea mays)秸秆、全珠四棱豆(Psophocarpus tetragonolobus)和精料为原料调配的全混合日粮(TMR)发酵品质及有氧稳定性的影响。试验设对照组(C,无添加)、双乙酸钠添加组(S,0.5%鲜重)、糖蜜添加组(M,3%鲜重)以及双乙酸钠 +糖蜜组合添加组(SM,0.5% + 3%鲜重) 4个处理。在温室25 ℃下青贮发酵35 d,开袋后取样测定其发酵品质。并将所有TMR暴露在空气中,分别在第0、 3、6、9、12和15天取样分析其有氧稳定性。结果表明,青贮35 d后,各组的氨态氮/总氮均低于100 g·kg~(-1) DM,且丙酸(1.06~1.54 g·kg~(-1) DM)和丁酸(1.66~4.64 g·kg~(-1) DM)...

This study explored the effects of sodium diacetate and molasses on the fermentation quality and aerobic stability of silage with rice straw, corn stalk, whole bead, and fine material. The experiment was divided into four groups: control group (C, no additive), sodium diacetate group (S, 0.5% FW), molasses group (M, 3% FW), sodium diacetate and molasses group (SM, 0.5% + 3% FW). After 35 days of fermentation, all total mixed rations (TMRs) were exposed to air and samples were analyzed on the 0th, 3rd, 6th, 9th, 12th, and 15th days for analysis ...
