家禽回肠内源氨基酸损失测定方法和影响因素

Determination methods and influencing factors of ileal endogenous amino acid losses in poultry

氨基酸消化率是评定家禽饲料蛋白质营养价值的重要指标,评定氨基酸消化率对家禽精准饲养具有重要意义。计算氨基酸消化率必须测定内源氨基酸损失。内源氨基酸损失不仅与测定方法有关,还受到动物种类、环境状况、日粮组成等因素影响。文章针对内源氨基酸损失的测定方法及其影响因素进行综述,以期为准确测定家禽内源氨基酸损失提供参考。

Amino acid digestibility is an important aspect to evaluate the nutritional value of feed protein in poultry.It is important to evaluate amino acid digestibility for accurate poultry feeding.The calculation of amino acid digestibility must measure the amount of endogenous amino acid losses.The endogenous amino acid losses are not only related to the determination method,but also affected by animal species,environmental conditions,dietary feed composition and other factors.The paper reviews the methods and influencing factors for the determination of endogenous amino acid losses,aiming at providing reference for the accurate determination of endogenous amino acid losses in poultry.
