摘　　要：将２５０只１日龄健康肉用雏鸡随机分为五组，分别饲喂赖氨酸、精氨酸比例（Ｌ／Ａ）为１４８∶１，１２２∶１，１∶１１８，１∶１４５和１∶１７５的玉米豆粕型日粮。试验结果表明，不同Ｌ／Ａ比例对肉鸡的生产性能有显著影响。在美国ＮＲＣ（１９９４）推荐的需要量基础上提高日粮赖氨酸含量，将导致肉鸡生产性能下降；而提高精氨酸含量至需要量的１５０％，对肉鸡的生产性能无不良影响。Anexperimentusingbroilersfedthecornsoybeanmealdietswith5gradedL/Aratios(1481,1221,1118,1145,1175)supplementedwithlysineHClandargininewasconducted.250initialbroilersweredividedinto5groupsrandomlyandeachgrouphadfivereplicates.TheresultsuggestedthatthedifferentratiosofL/Ahadasignificanteffectonfeedintake,dailyweightgainandfeed/gain,andtheexcessivelysinerestrainedgrowthperformance.WhenL/Awas1481,ithadlowestvaluesandthe1175hadhighestvalues.Excessivedietarylysinedecreasedretentingnitrogeninbroilers,butexcessiveargininemadenosignificanteffect.Whenthelysinehadahighlevelindiets,theserumtotalproteinwaslowersignificantlycomparedwithothergroups.Butnosignificanteffectwasfoundamonghighargininelevelgroups.
