摘　　要：本试验选择同一鸡舍内54周龄新罗曼褐壳蛋鸡400只随机分为5组,每组2个重复,每个重复40只鸡,以研究烟酸铬对蛋鸡生产性能的影响。烟酸铬(以铬计)的添加水平为:0,100×10-9,300×10-9,600×10-9,1000×10-9。试验期43天。结果表明:0、100×10-9、600×10-9的烟酸铬对蛋鸡产蛋率、料蛋比、日均采食量无显著影响(P>0.05),1000×10-9水平烟酸铬可提高蛋鸡的产蛋率7.00%和日均采食量6.61%(P<0.05),提高净蛋白利用率(NPU)12.93%(P<0.05)。A trial was conducted to evaluate the effect of organic chromium on performance of layer.The400new Roman layer of54weeks were randomly allotted one of five treatments:①basal diet;②basal+100×10 -9 Cr ;③basal+300×10 -9 Cr ;④basal+600×10 -9 Cr ;⑤basal+1000×10 -9 Cr.The results showed that:rate of lay,rate of feed and egg,ADI were in sig nificantly in layer diet supplement with0,100×10 -9 ,600×10 -9 of organic chromium.The rate of lay,ADI were signifi-cantly(P<0.05)and NPU is significantly(P<0.01)in layer diet supplement with1000×10 -9 Cr.
