6种饵料对小白鼠引诱作用的初步观察

目的寻找对小白鼠更具引诱力的饵料,为配制毒饵提供一定依据。方法采用摄食系数测定6种不同饵料（花生、豆饼、稻谷、马铃薯、猫料、鱼饵）对小白鼠的引诱效果。结果小白鼠对6种饵料的偏好性存在差异。其中马铃薯、花生对小白鼠的引诱效果最强,摄食系数为5.90和2.49,偏好性为优,平均取食率达60.71%和25.61%;豆饼和稻谷的引诱效果次之,摄食系数分别为1.08和1.16,偏好性也为优,取食率分别为14.49%和11.94%;鱼饵和猫料的引诱效果较弱,取食率分别仅为8.74%和3.00%,低于对照饵料——鼠粮的取食率（13.37%）。结论在配制鼠类毒饵时,可优先考虑更具引诱效果的马铃薯和花生;同时,随着投饵后时间的延长,持续引诱作用降低,其中以48 h后的减幅最大。此外,在研制灭鼠剂时,应考虑饵料的营养平衡或不同类型饵料的交替使用,以提高诱饵的适口性。

Preliminary observation of the attracting effect of six mice baits

Objective To identify the most attractive mice baits for preparation of toxic baits.Methods The attracting effects of six types of bait(peanut,rice,potato,bean cake,fish bait,and cat food) on mice were determined in terms of the respective feeding coefficients.Results Mice showed different preferences for the six baits,of which potatoes and peanuts had the strongest attracting effects with feeding coefficients of 5.90 and 2.49,respectively,and average feeding rates of 60.71% and 25.61%,respectively.Bean cak...
