摘　　要：本试验选用３２周龄蛋鸡（罗曼）７２只，随机分成６组。在基础日粮含硒（Ｓｅ）０．１ｍｇ／ｋｇ基础上，添加亚硒酸钠ＶＥ粉，各组Ｓｅ的添加水平分别是０、０．５、１．０、１．５、２．０、３．０ｍｇ／ｋｇ；日粮ＶＥ的添加水平分别是０、４１．６６、８３．３２、１２４．９８、１６６．６４、２４９．９６ＩＵ，试验期８周。以此探索不同剂量的Ｓｅ和ＶＥ对蛋鸡生产性能的影响及Ｓｅ和ＶＥ的摄入与其在蛋中沉积的关系。试验结果表明，添加１ｍｇ／ｋｇＳｅ、８３．３２ＩＵＶＥ组鸡产蛋率显著高于其它各组，而各组鸡蛋重差异不显著；日粮中添加２．０ｍｇ／ｋｇＳｅ时，可使蛋中硒含量达最高值（１．８５μｇ／ｇ），添加１２４．９８ＩＵＶＥ可使蛋中ＶＥ含量达到最高值（３．７１μｇ／１００ｇ）。试验证明，日粮中添加１．０～２．０ｍｇ／ｋｇＳｅ、８３．３２～１６６．６４ＩＵＶＥ不仅可提高蛋鸡生产性能。Healthy eight month layers were allotted randomly into six threatment groups of twelve layers The effect of dietary Se and VE level on laying hens performance and Se and VE concentration in eggs were studied Amounts of added to basal cornsoybean diet Se(mg/kg)and VE (IU)were 0 and 0,0 5 and 41 66,1 and 83 32,1 5 and 124 98,2 and 166 64,3 and 249.96 The results of feeding experiment showed that supplement adequate Se and VE (1mg/kg,83 32IU)in diet was significantly increased laying rate( P <0 01) Adding 2 0mg/kg Se and 124 98IU VE in diets,the concentration of Se and VE in eggs were highest,gone up to 1 85μg/kg(Se)and 3 71μg/100g(VE)respectively The result showed that added 1 0～2 0mg/kg Se and 83 32～166 64IU VE in diet of laying hens,not only increased laying rates,but also improved the deposition of Se and VE in eggs
