摘　　要：设计了牛蛙诱食迷宫装置,探究6种常见脂肪源对牛蛙的诱食效果。在未添加脂肪源的豆粕型饲料中分别外喷6%的淡水鱼油、海水鱼油、大豆油、棕榈油、鸡油和猪油制备的6种试验饲料。以摄食饲料颗粒的百分数、10 min内进入摄食区牛蛙的百分数、第一只牛蛙进入摄食区的时间和牛蛙的运动轨迹作为各脂肪源诱食效果的评价指标,并两两对比6种脂肪源的诱食效果。结果表明,添加海水鱼油的饲料对牛蛙的诱食效果显著高于未添加脂肪源的豆粕型饲料(P<0.05),证明了此迷宫装置可用于牛蛙的诱食研究。以摄食饲料的颗粒百分数为指标,测得6种脂肪源对牛蛙的诱食效果为:淡水鱼油=大豆油>海水鱼油=棕榈油=鸡油=猪油;分析10 min内进入摄食区牛蛙的百分数,认为6种脂肪源对牛蛙的诱食效果为:淡水鱼油=大豆油>海水鱼油≥棕榈油≥鸡油≥猪油;对第一只牛蛙进入摄食区的时间进行分析,得出各脂肪源的诱食效果为:大豆油≥淡水鱼油>海水鱼油=棕榈油≥鸡油>猪油;牛蛙的运动轨迹显示,各脂肪源的诱食效果为:淡水鱼油=大豆油>海水鱼油≥棕榈油≥鸡油>猪油。综上所述,该诱食迷宫装置可以用于对比不同诱食剂对牛蛙的诱食效果;并且6种脂肪源对牛蛙的诱食效果为:淡水鱼油=大豆油>棕榈油=海水鱼油>鸡油>猪油。This study was designed to determine the effects of lipid sources as feed attractants on bullfrog(Lithobates catesbeiana).Six kinds of experimental diets were prepared by spraying 6%freshwater fish oil,seawater fish oil,soybean oil,palm oil,poultry fat and lard in soybean meal diet without lipid sources.The percentage of particles fed by bullfrog,the percentage of bullfrogs entering the feeding area within ten minutes,the time when the first bullfrog entered the feeding area and the motion track of bullfrogs were indexes to evaluate the feeding attractant effects of each lipid sources which compared in pairs.The results showed that the attractant effect of diet with seawater fish oil on bullfrog was significantly higher than that of soybean meal diet without lipid sources.This result proved that the maze device was feasibility for bullfrog,and seawater fish oil had the attractant effect to bullfrog.Based on the percentage of particles fed,the attractant effects of lipid sources on bullfrog were as follows:freshwater fish oil=soybean oil>seawater fish oil=palm oil=poultry fat=lard.Based on the percentage of bullfrog entering the feeding area,the attractant effects of lipid sources on bullfrog were as follows:freshwater fish oil=soybean oil>seawater fish oil≥palm oil≥poultry fatl≥lard.Based on the analysis of the time when the first bullfrog entered the feeding area,the attractant effects of lipid sources on bullfrog were as follows:soybean oil≥freshwater fish oil>seawater fish oil=palm oil≥poultry fat>lard.The motion track of bullfrog showed that the attractant effect of lipid sources on bullfrog were as follows:freshwater fish oil=soybean oil>seawater fish oil≥palm oil≥poultry fat>lard.In summary,the maze device could be used to bullfrog’s attractant selection.Lipid sources had attractant effects to bullfrog.The attractant effect of six kinds of lipid sources on bullfrog were as follows:freshwater fish oil=soybean oil>palm oil=seawater fish oil>poultry fat>lard.
