肉雞飲料配方的經濟分析-營養素相關性對飼料生産成本之影響

An Economic Analysis on Boiler Feed Formulation-The Impact of Nutrient Correlation upon Feed Costs

摘要


本文透過模擬程序,針對肉雞飼料原料中營養素間的共變異數性質從所可能産生的經濟效果進行研討。透過修正機會限制規劃法,以本省肉雞生産資料,考量玉米以及大豆粕兩種原料中蛋白質與熱能兩種營養素爲例估測後,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。雖然單位金額減少幅度相當有限,然而在考量肉雞生産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 and 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 of feed and its importance as a large share of variable costs in broiler production imply that the gains may be significant.
