Abstract: In order to explore the best way of storing alfalfa hay,the influence of compound natural mold inhibitor including calcium oxide(CaO),dried tangerine peel and zeolite powder on the nutritional value of alfalfa hay bale was studied.Result sshowed that:FR treatment(spraying with 2.5% potassium carbonate and pressing flat with sundried infield to 28%~30% moisture content,then adding mold inhibitor),lost less nutrition than others in the storage process.Its CP(Crude protein)content only decreased from 19.21% to 18.17% during storage process.NDF(Nutral detergent fibre)content was 51.13% and AD(Acid detergent fibre)content was 39.54% after the storage process.Both contents were significantly low Ferin FR treatment than othert treatments.Changes of EE(Ether extract)and CF(Curde fiber)during storage were relatively small.

摘要： 为探索苜蓿(Medicago sativa)干草捆贮藏的最佳方式,以氧化钙(CaO)、陈皮、沸石粉为原料配制复合型天然防霉剂,并以草原2号苜蓿为材料,对复合型天然防霉剂在苜蓿干草贮藏期营养价值的影响进行了研究.结果表明:在整个贮藏过程中,FR处理(压扁结合喷施2.%碳酸钾进行田间晒制,干草含水量为28%～30%,添加复合型天然防霉剂)较其他各处理其营养成分含量损失较少,粗蛋白(Crude protein,CP)含量由打捆初期的19.21%降至18.17%,整个贮藏过程中CP含量仅下降了 1.04%,较其他各处理CP损失最少;中性洗涤纤维(Nutral deter-gent fibre,NDF)、酸性洗涤纤维(Acid detergent fibre,ADF)在贮藏后含量为1.13%,39.4%,显著低于其他各处理,粗脂肪(Ether extract,EE)、粗纤维(Curde fiber,CF)在贮藏过程中变化相对较小.
