| 摘 要： | 在炎热的夏季,用不同的蛋白能量比日粮(14.82,15.68,14.34)饲喂蛋鸡结果表明,提高日粮中的蛋白含量比对照组产蛋率高3.59个百分点,蛋重高0.79g(1.26％)。而增加日粮中的能量比对照组降低产蛋率2.03个百分点,蛋重降低1.26g(2.01％)。

| Abstract: | The laying hens were fed on diets of different protein energy ratio (14.34, 14.82,15.68) in hot summer. The result showed that the rate of laying increased by 3.59 percent (4.49%), the weight of egg went up 0.79 gram/egg (by 1.26%) when the proteinlevel of diets increased, while the rate of laying and the weight of egg decreased by 2.03per cent and 2.01% (1.26 gram). |
