摘要
提出了估计肉鸭氨基酸需要的数学模型。用生长鸭的比较屠宰试验和成年鸭的氮平衡试验对模型的某些参数进行了估计，并用该模型对生长由鸭各生长阶段的氨基酸需要量进行了估计。结果表明用该模型估计的肉鸭前期氨基酸需要量和文献报道值很吻合（ｒ＝０．９４），后期的估计值普遍低于文献报道值。
A mathmatics model was constructed to estimate the amino acid requirelnent ofducklings.A comparative slaughter trial in ducklings and a nitrogen balance trial inadult duck were conducted to estimate some parameters in the model.The amino acidrequirement for ducklings in each period was estimated using the model. For 0～3week, tlie estimated requirement was similiar to the literature data, however, it waslower than the literature data for 4～7 week.
