本文透模擬程序，針對肉雞飼料原料中營養素間的共變異數性質後所可能產生的經 經濟效果進行研討。透過修正機會限制規劃法，以本省肉雞生產資料，考量玉米以及大豆務 兩種原料中蛋白質與熱能兩種營養素為例估測後，結果顯示在通過飼料中相關營養素含量必 須符合規定的機率水準下，飼料成分中營養素間的正相關性質，的確會降低飼料成品的成本。 雖然單伅金額減少幅度相當有限，然而在考量肉雞生產中飼料使用量以及飼料支出項佔變動 成本的比例後，獲利應是相當顯著的。

　　　　　The economic advantages of taking account of the covariance between nutrients in boiler feed ingredients were investigated through a hypothetical example. These initial experiments suggest that knowledge of correlation between nutrients for feed ingredients gives an advantage for reducing the cost of feed subject to a target for the probability of satisfying nutrient requirement. While the gains are modest, the volume feed and its importance as a large share of variable costs in broiler production imply that ht gains may be significant.
