Abstract The ensiling process, as well as the hybrid type and moisture content of corn grains, can affect the fermentation profile and nutrient digestibility of grain silages. Therefore, this study evaluated the effects of hybrid type, grain moisture content at harvest, and length of storage on the fermentation profile, DM digestibility (DMD), and starch digestibility (StarchD) of corn grain silages. We evaluated corn grains harvested at three moisture contents: at approximately 500 g/kg DM (500DM); high-moisture corn at approximately 700 g/kg DM (HMC); and dry grain at approximately 800 g/kg DM, reconstituted to approximately 700 g/kg DM (RC). At RC and HMC, the flint hybrid had an average of 24 % higher (P

杂交种、水分和储存时间对玉米青贮饲料发酵曲线和淀粉消化率的影响

摘要 青贮过程以及玉米粒的杂交类型和水分含量会影响谷物青贮饲料的发酵特性和养分消化率。因此，本研究评估了杂交类型、收获时谷物水分含量和储存时间对玉米青贮饲料发酵曲线、干物质消化率 (DMD) 和淀粉消化率 (StarchD) 的影响。我们评估了在三种水分含量下收获的玉米粒：大约 500 g/kg DM (500DM)；约 700 g/kg DM (HMC) 的高水分玉米；干粮约 800 g/kg DM，重组为约 700 g/kg DM (RC)。在 RC 和 HMC，燧石混合动力车平均高出 24%（P
