摘　　要：选择新出壳罗曼蛋鸡 42 4羽 ,研究了日粮中分别添加 0 %、0 .1 5 %、0 .2 5 %、0 .35 %的低聚糖对蛋雏鸡生长性能及粪臭的影响。试验结果表明 :0～ 6周龄日粮添加 0 .1 5～ 0 .35 %的低聚糖 ,可使蛋雏鸡的 ADG、F/G显著高于对照组 ( P<0 .0 5 ) ;添加低聚糖 0 .1 5 % ,氮的排泄率低于对照组 ( P<0 .0 5 ) ,粪便 H2 S释放量极显著低于对照组 ( P<0 .0 1 ) ;日粮添加 0 .1 5 %～ 0 .35 %低聚糖 ,粪便氨释放量显著低于对照组 ( P<0 .0 5 )。0～ 6周龄蛋雏鸡日粮中低聚糖适宜添加量为 :0 .1 5 %～ 0 .2 3%。A trial was conducted to evaluate the effect of oligosaccharide on growth and waste gas of little layer. 424 zero old Roman layer were randomly alloted one of four treatments: 1)basal diet; 2)basal+0.15% oligosaccharide; 3)basal+0.25% oligosaccharide; 4)basal+0.35% oligosaccharide. ADG, F/G was significantly increased ( P <0.05) in little layer fed diet supplemently with 0.15%~0.35% of oligosaccharide. 0.15% was added to diet, N significantly induce ( P <0.05) and H 2S significantly induce ( P <0.01). NH 3 was significantly increased ( P <0.05) in little layer fed diet supplemently with 0.15%~0.35% of oligosaccharide. The best addition of oligosaccharide is 0.15% to 0.23% on zero to six weeks' littler layer.\;
