中文摘要：试验旨在对南方常见6种农副产品花生秧、火龙果藤、香蕉叶、海水稻秸秆、玉米秸秆、普通水稻秸秆进行营养价值评定。试验采用单因素随机设计,将采集的样品分为3组,进行常规营养成分测定和模拟瘤胃体外发酵试验。结果显示,花生秧的粗蛋白(CP)含量最高(P<0.05),香蕉叶粗脂肪(CF)含量最高(P<0.05),海水稻秸秆粗纤维含量最高(P<0.05),火龙果藤中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)最低(P<0.05);火龙果藤的相对饲喂价值(RFV)、质量指数(QI)、粗饲料分级指数(GI)、消化能(DE)、代谢能(ME)和增重净能(NEg)显著高于其他5种饲料(P<0.05);雷州山羊瘤胃液体外发酵后火龙果藤产气量最高(P<0.05);氨态氮(NH_3-N)的含量依次为玉米秸秆>火龙果藤>花生秧>海水稻秸秆>普通水稻秸秆>香蕉叶;干物质消化率(IVDMD)依次为火龙果藤>玉米秸秆>普通水稻秸秆>海水稻秸秆>花生秧>香蕉叶。研究表明,6种农副产品饲料营养价值、饲用价值及体外发酵降解结果存在明显差异,隶属函数综合评估营养价值依次为火龙果藤>花生秧>玉米秸秆>普通水稻秸秆>海水稻秸秆>香蕉叶。

外文摘要：The study was to analyze six common agricultural and sideline products in southern China,peanut vines,evaluated pitaya vines,banana leaves,sea rice straw,zea mays straw and corn straw nutritional value.The experiment adopted a single-factor randomized design and sample materials were divided into three groups,and routine nutrient composition determination and simulated rumen in vitro fermentation experiment were carried out.The results showed that peanut vines had the highest CP content(P<0.05),banana leaves had the highest CF content(P<0.05),sea rice straw had the highest crude fiber content(P<0.05),and pitaya vines had the lowest NDF and ADF(P<0.05).The RFV,QI,GI,DE,ME and NEg of pitaya vines were significantly higher than those of other five samples(P<0.05).The highest gas production was obtained from pitaya vines after liquid external fermentation in rumen of Leizhou goats(P<0.05).The content of NH-N was zea mays straw>pitaya vines>peanut vines>sea rice straw>corn straw>banana leaves.The IVDMD was pitaya vines>zea mays straw>corn straw>sea rice straw>peanut vines>banana leaves.The study indicates that nutritional value,feeding value and in vitro fermentation degradation results of six agricultural by-products are different,and affiliation function integrally assesses nutritional value in order of pitaya vines>peanut vines>zea mays straw>corn straw>sea rice straw>banana leaves.
