不同剂量甘果寡糖对鲤生长和运输的影响

Effects of Oligomannose and Fructose Levels on Growth and Transport of Carp

选用初始体重为 180～ 190g的正常健康鲤 10 8尾 ,分成 3组 ,每组 36尾 ,每组设 3个重复。实验用 3种处理 ,即对照组 (基础饵料 )、基础饵料 +30 0× 10 -6甘果寡糖、基础饵料 +6 0 0× 10 -6甘果寡糖 ,在实验 6 0d后每个处理组用 12尾鱼作运输试验 ,运输距离 5 0 0km ,运输时间近 14h。研究结果表明 :在基础饵料中 ,添加寡糖显著地提高生长速度和饵料利用率 (P <0 0 1) 。

carp with 180～190 g weight were divided three groups,which was given the diets containing oligomannose and fructose 0,300×10 -6 and 600×10 -6 respectively for 60 days,then 12 crap of every group were transported 500 km for 14 h by bus.The growth rate and feed efficiency rate was increased great significantly ( P <0 01),and the resistant transport ability do not effected by oligomannose and fructose.
