摘　　要：试验旨在测定芦苇菇菇脚类废弃物的营养成分,评价其营养价值。采用饲料常规养分测定方法测定芦苇菇菇脚类废弃物粗蛋白、粗脂肪、水分、粗灰分和主要微量元素的含量,采用国际通用的非生物评价法,评价蛋白质的营养价值。结果表明:芦苇菇菇脚类废弃物含有粗蛋白24.76%、粗脂肪0.29%、水分11.78%、粗灰分7.46%;矿物元素含量分别为铜57 mg/kg、铁212 mg/kg、锰31 mg/kg、锌66 mg/kg;检测到17种氨基酸,其中必需氨基酸(EAA)与总氨基酸(TAA)的比值为0.40,非必需氨基酸(NEAA)与TAA比值为0.60。氨基酸评分(AAS)结果显示:芦苇菇菇脚类废弃物作为鸡饲料原料时,缬氨酸为第一限制性氨基酸,蛋氨酸为第二限制性氨基酸,蛋氨酸+胱氨酸为第三限制性氨基酸;芦苇菇菇脚类废弃物的必需氨基酸相对比值(EAARR)为66.5%,灰色关联度(GRG)评分为0.78。研究表明,芦苇菇菇脚类废弃物可以作为一种优质的蛋白质饲料原料资源,具有开发应用价值。The experiment aims to determine the nutritional components of reed mushroom foot waste and evaluate its nutritional value.The conventional feed nutrient determination method was used to measure the content of crude protein,crude fat,moisture,crude ash,and main trace elements in reed mushroom foot waste.The internationally accepted nonbiological evaluation method was used to assess the nutritional value of protein.The results showed that the reed mushroom foot waste contained 24.76%crude protein,0.29% crude fat,11.78% moisture and 7.46% crude ash,the content of main mineral elements in reed mushroom foot waste was Cu 57 mg/kg,Fe 212 mg/kg,Mn 31 mg/kg and Zn 66 mg/kg.A total of 17 kinds of amino acids were detected in reed mushroom foot waste.The ratio of essential amino acids(EAA)to the total amino acids(TAA)was 0.40,and the ratio of non-essential amino acids(NEAA)to TAA was 0.60.The results of AAS showed that the first limiting amino acid was valine,the second limiting amino acid was methionine,and the third limiting amino acid was methionine+cystine.The EAARR score of reed mushroom foot waste was 66.5%,and the GRG method score was 0.78.The study indicates that reed mushroom foot waste can be used as a high quality protein feed raw material,which has the value of development and application.
