摘　　要： 在高温季节（２５．５℃－３９．４℃），配制５种日粮，分别将其喂蛋鸡。第一种日粮（对照组）按现行饲养标准配制。对第２－５种，不同程度地调整其中代谢能、粗蛋白及必需氨基酸等主要养分的浓度。饲养结果表明，与对照组比较，采食第４种日粮的蛋鸡产蛋率提高１５．２０％（Ｐ＜０．０１），饲料用于产蛋的效率提高１５．７０％（Ｐ＜０．０１），产蛋饲料成本降低８．９％（Ｐ＜０．０５）；采食第５种日粮的蛋鸡产蛋率提高１０．５５％（Ｐ＜０．０５），饲料用于产蛋的效率蜇高９．９９％（Ｐ＜０．０５），但产蛋饲成本增加１１．６７％（Ｐ＜０．０５）；采食第２种日粮的蛋鸡产蛋率和饲料效率降低，饲料成本提高，但均不显著（Ｐ＞０．０５）；采食第３种日粮的蛋鸡产蛋率、饲料效率和产蛋饲料成本均与对照组相似。 During high temperature(25.5-39.4℃),5 diets were made. The diet 1(control)was made according to now-used feeding dtandard.There were some proiper ad-justment for ME,CP,EAA,Ca,P and other mutruents in diet 2-5. Feeding results show:as compared with control,Laying rate of layer fed to diet 4 increased by 15.20%(P<0.01),feed utilization efficiency increased by 15.70%P<0.01),feed cost decreased by 8.9%(P< 0.05 );laying rate,fed utilization efficiency and feed cost of Layer fed to diet 5 in-creased by 10. 55%(P<0.05), 99%(P<0.05)and 11. 67%(P<0.05)respectively.Laying rate and feed utilization efficiency of Layer fed to diet2 were lower,but feed cost was higher than control(P<0.05),Laying rate,feed utilization efficiency and feed cost of layer fed to diet 3 were similar to control.
