本實驗的目的在於瞭解本省成鰻、幼鰻及鰻線用三類飼料之品質狀況。調查結果發現三類鰻
用飼料之一般成分含量雖各有差異，但大部份均符合國家標準。三類鰻用飼料之一般成分的平均
含量，依蛋白質、無氮抽出物、灰分、水分、脂質、粗纖維之次序而降低。除脂質之外，三類鰻
用飼料之一般成分的平均值之間有相關關係存在，其蛋白質的平均含量以鰻線用飼料為最高，幼
鰻飼料次之，而以成鰻用飼料為最低；但無氮抽出物、灰分、水分及粗纖維的平均含量則與此相
反，以鰻線用飼料為最低，幼鰻飼料次之，而以成鰻用飼料為最高。三類鰻用飼料之揮發性鹽基
態氮、?(口?)、組織胺等腐敗分解產物的平均含量與油脂酸價的平均值彼此之間則沒有相關關係存
在。又各飼料之腐敗分解產物含量與油脂酸價雖然差異很大，但絕大部份均介於用已知成分的日
本白魚粉和臺灣褐魚粉調製而成的鰻魚飼料之間。
三類鰻用飼料的品質指標之變異係數，就一般成分而言，以粗纖維的變異係數最大，蛋白質
的變異係數最小；就腐敗分解產物而言，以 VB-N/AA-N 值及?(口?)的變異係數最大，而以揮發
性鹽基態氮及組織胺的變異係數較小，品質指標中變異係數超過 30% 的有 VB-N/AA-N 值、?

The proximate compositions of eelfeeds varied considerably. However, most ofthem were in accord with the Chinese NationalStandard. The average contents of protein, ni-trogen free extracts, ash, moisture, lipid, fiberwere in decending order. Among these eel feeds,no statistical correlation was found between acidvalue and decomposition products, such as vola-tile basic nitrogen, indole and histamine. Base on coefficients of variance of qualityindices of eel feeds, it was found that: (1) amongthe proximate compositions, the coefficient offiber was the highest and the protein was thelowest, (2) the coefficient of variance of VB-N/AA-N value was the highest and the VB-Nand histamine were lower among the productsof decomposition, (3) VB-N/AA-N value, indole,VB-N, histamine, acid value, sand and silica,fiber, amino nitrogen and essential amino acidindex showed coefficients of variance higher than30% and therefore were suggested to includethem as quality indices in Chinese NationalStandard.
