摘　　要：以甘蔗尾梢为主要原料,采用分级固态发酵技术研究生产甘蔗尾梢饲料的工艺条件,通过单因素和正交实验,对一级发酵工艺中接种量、水分含量、一级发酵时间和二级发酵工艺中精粗比、二级发酵时间5个因素进行了优化。结果表明:当接种0.15%发酵菌剂于一级发酵底物中,调整其水分含量为50%,密封常温发酵5 d后按3∶7比例将一级发酵料与新鲜甘蔗尾梢混合均匀,压实密封进行二级发酵,21 d后甘蔗尾梢饲料品质最佳。所得甘蔗尾梢饲料粗蛋白含量为15.24%,粗纤维含量为24.03%。分级固态发酵技术可快速、有效提高甘蔗尾梢饲料中粗蛋白含量,同时降解粗纤维,改善饲料适口性,可应用于甘蔗尾梢饲料的制备。The aim of the experiment was to study the technological conditions of producing sugarcane caudate lobe feed production by the sectional solid-state fermentation technology.The raw material was sugarcane caudate lobe,five factors including inoculum quantity,moisture content,first stage fermentation time,concentrated-roughage and second stage fermentation time were optimized through single factor and orthogonal experiments.The results showed that when inoculated 0.15% fermenting microbe in the first stage fermentation substrate,adjusted the moisture content to 50%,sealed and fermented at normal atmospheric temperature,mixed with fresh sugarcane caudate lobe in the concentrated-roughage ratios of 3∶7 and compacted and sealed after 5 days,the quality of sugarcane caudate lobe feed would be the best after 21 days.According to the technological conditions,the crude protein and crude fiber content of sugarcane caudate lobe feed was respectively 15.24% and 24.03%.The technology of sectional solid-state fermentation could rapidly and effectively improve the crude protein content,degrade crude fiber and improve sugarcane caudate feed palatability.It could be applied to the preparation of sugarcane caudate lobe feed.
