An experiment was conducted to determine the response of growing Japanese quail to two dietary energy levels, high (3,200 kcal ME/kg) versus low (3,000 kcal ME/kg), and two forms of presentation, mash versus pellet. Seven thousand, two hundred day-old Japanese quail (Coturnix coturnix japonica) were randomly distributed into 24 floor pens containing 300 quail each. The experiment was divided in two phases: starter (until 2 wk of age) and finisher (Days 14 to 33). Weight gain was less (P < .05) for quail fed the low-energy mash diet than for those on other treatments. Feed consumption increased (P < .001) when low-energy and mash diets were fed. Metabolizable energy consumption was greater with the mash diets. Feed conversion improved (P < .001) when high-energy and pelleted diets were fed as compared with low-energy and mash diets, respectively. Results indicated that daily gain and feed conversion of quail fed the low-energy, pelleted diet equaled those of quail fed the high-energy mash diet. Pelleting improved the caloric efficiency of gain by quail. Quail seemed to adjust caloric intake according to the energy level of the diet.
进行了一项实验，以确定生长中的日本鹌鹑对两种日粮能量水平（高能量，3200千卡代谢能/千克；低能量，3000千卡代谢能/千克）以及两种日粮形式（粉料与颗粒料）的反应。7200只1日龄日本鹌鹑（日本鹌鹑）被随机分配到24个地面饲养栏中，每个饲养栏有300只鹌鹑。实验分为两个阶段：育雏期（直到2周龄）和育肥期（第14至33天）。饲喂低能量粉料日粮的鹌鹑体重增加较少（P < 0.05），低于其他处理组的鹌鹑。饲喂低能量和粉料日粮时，采食量增加（P < 0.001）。粉料日粮的代谢能消耗更高。与低能量和粉料日粮相比，分别饲喂高能量和颗粒料日粮时，饲料转化率提高（P < 0.001）。结果表明，饲喂低能量颗粒料日粮的鹌鹑的日增重和饲料转化率与饲喂高能量粉料日粮的鹌鹑相当。制粒提高了鹌鹑增重的热量效率。鹌鹑似乎会根据日粮的能量水平调整热量摄入。
