The requirements for leucine, isoleucine and valine were determined in 8- to 18-d-old White Leghorn male chicks. The requirements were estimated from body-weight gains. The estimated requirements for leucine, isoleucine and valine were 200, 115 and 125 mg/bird d, or 12.0, 5.0 and 8.0 g/kg diet, respectively. In terms of concentration in the diet, they are broadly similar to results for broiler-type chicks. When body-weight gain was plotted against daily intakes of each amino acid, significant (P less than 0.01) quadratic regression equations were obtained. The equations showed some characteristics of the individual amino acids.
在8至18日龄的白来航雄性雏鸡中测定了亮氨酸、异亮氨酸和缬氨酸的需求量。需求量根据体重增加情况进行估算。亮氨酸、异亮氨酸和缬氨酸的估算需求量分别为每只鸡每天200毫克、115毫克和125毫克，或每千克日粮12.0克、5.0克和8.0克。就日粮中的浓度而言，它们与肉仔鸡型雏鸡的结果大致相似。当将体重增加量与每种氨基酸的每日摄入量作图时，得到了显著（P小于0.01）的二次回归方程。这些方程显示了个别氨基酸的一些特性。
