Two experiments were conducted to evaluate the protein requirement of adult bobwhite quail. Flight-type quail were used in one experiment and meat-type quail in the other. Corn and soybean meal diets containing 12, 15, 18, 21, and 24% protein were fed. Increasing the protein level of the diet from 12 to 15% significantly increased egg production with the flight-type bird. However, only a nonsignificant increase in egg production was obtained with the meat-type birds when the protein level was increased to 15%. Higher levels of protein did not result in further increases in egg production in either strain. Increasing the protein from 12 to 18% (flight) or 21% (meat) resulted in increased egg weight. Egg mass of flight-type hens receiving 18 and 21% protein was significantly greater than egg mass from hens receiving 12 and 15% protein. Hatch of fertile eggs, hatch of total eggs, chick weight, or weight of adult birds were not affected by protein level. Feeding the 12% protein diet resulted in significantly reduced fertility in the flight-type birds but not in the meat-type birds.
进行了两项实验来评估成年北美鹑的蛋白质需求量。一项实验使用飞行型鹌鹑，另一项使用肉用型鹌鹑。投喂了含12%、15%、18%、21%和24%蛋白质的玉米和豆粕日粮。对于飞行型鹌鹑，将日粮蛋白质水平从12%提高到15%显著增加了产蛋量。然而，对于肉用型鹌鹑，当蛋白质水平提高到15%时，产蛋量仅出现了不显著的增加。更高的蛋白质水平在两种品系中均未导致产蛋量进一步增加。将蛋白质从12%提高到18%（飞行型）或21%（肉用型）导致蛋重增加。摄入18%和21%蛋白质的飞行型母鸡的蛋重显著高于摄入12%和15%蛋白质的母鸡。受精蛋孵化率、总蛋孵化率、雏鸡体重或成年鸟体重不受蛋白质水平影响。投喂12%蛋白质日粮导致飞行型鹌鹑的受精率显著降低，但肉用型鹌鹑不受影响。
