Two experiments were conducted to determine if Bobwhite quail chicks would adjust feed consumption according to energy intake from hatching to five weeks of age. Three starter diets, which were calculated to contain 2850, 3010 and 3170 Kcal. M.E./Kg., were fed throughout the five-week experiments. As energy was increased, the protein level was increased proportionally. Each treatment group consisted of four replicate pens containing 125 chicks each. Body weight at two and five weeks of age was not affected by treatment, except for a reduction at two weeks for birds on the 3170 Kcal./Kg. diet. There were no significant treatment effects on mortality. The feed consumed/bird/day decreased as dietary energy was increased. The calculated energy consumption/bird/day was 15.44, 15.31 and 14.79 Kcal., respectively, for the 2850, 3010 and 3170 Kcal. M.E./Kg diets during the five-week period. The energy and protein consumption per gram of body weight was slightly reduced at the high energy level indicating a more efficient use of energy and protein of the high energy diet. These data indicate that the Bobwhite quail adjusts feed intake according to the energy content of the diet.
进行了两项实验，以确定美国鹧鸪雏鸡从孵化到五周龄是否会根据能量摄入量调整采食量。在为期五周的实验中，全程投喂三种起始日粮，经计算其每千克代谢能分别为2850、3010和3170千卡。随着能量增加，蛋白质水平按比例增加。每个处理组由四个重复栏组成，每个栏中有125只雏鸡。两周龄和五周龄时的体重不受处理影响，但采食每千克含3170千卡日粮的雏鸡在两周龄时体重有所下降。处理对死亡率没有显著影响。随着日粮能量增加，每只鸟每天的采食量下降。在五周期间，每千克代谢能为2850、3010和3170千卡的日粮，每只鸟每天的计算能量摄入量分别为15.44、15.31和14.79千卡。在高能量水平下，每克体重的能量和蛋白质摄入量略有减少，这表明高能量日粮对能量和蛋白质的利用效率更高。这些数据表明，美国鹧鸪会根据日粮的能量含量调整采食量。
