摘要

濃縮糖蜜發酵液(CMS)是生產離胺酸或味精的副產品。本試驗在室外FRP桶中飼養吳郭魚稚魚來探討在實用飼料中以CMS取代脫脂的黃豆粉(SBM)作為蛋白質源的可行性。基礎飼料包含9.9%魚粉，5.0% SBM，及33.3%脫脂SBM作為含32%飼料粗蛋白的主要蛋白質源，其中脫脂SBM的蛋白質自0~100%以20%的間隔的CMS的蛋白質取代。這6種飼料以3重複餵魚6星期。結果顯示隨著CMS含量的增加，魚成長表現及飼料效率降低，而且魚體中灰分含量增加，這可能歸諸於與脫脂黃豆粉比較，CMS的灰分及鈉離子含量較高，能量較低，以及胺基酸組成較不均衡。然而，20%的取代率並未導致成長、飼料效率、及魚體成分的差異。因此CMS仍可考慮作為吳郭魚實用飼料中部分取代黃豆粉的蛋白質源。

Condensed molasses fermentation soluble (CMS) is a byproduct of production of lysine or monosodium glutamate. A feeding trial was conducted in outdoor fiberglass reinforced polyethylene tanks with fingerling Nile tilapia (Oreochromis niloticus) to investigate the feasibility of using CMS as a protein source replacement for defatted soybean meal (SBM) in a practical diet. The basal diet contained 9.9% fishmeal, 5.0% SBM and 33.3% defatted SBM as major protein sources providing for 32% dietary crude protein level in which the defatted SBM protein fraction was replaced by CMS protein from 0-100% at a 20% interval. There were total of six experimental diets, each diet was fed to triplicate groups of fish for 6 weeks. The results indicated that as CMS level increased, growth performance and feed efficiency decrease, and body ash content of the resulting fish increased, which could be attributed to higher ash and sodium content, lower energy, and more unbalanced amino acid profile in CMS than in defatted SBM. However, 20% protein replacement of defatted SBM by CMS did not make differences in growth performance, feed efficiency, and body composition of the resulting fish. Therefore, CMS can still be considered as a promising alternative protein source for partial substitute of soybean meal in the practical diet of tilapia.
