摘　　要：[Objectives]This study was conducted to select suitable mouse beddings from commercial corncob bedding(A-E)produced by five different manufacturers.[Methods]The physical properties and microbial indexes of the five kinds of corncob bedding were studied by means of visual inspection,dust content determination,moisture content determination,water absorption tests and microbial detection.[Results]In visual inspection,corncob bedding A was better than other four kinds.During dust content determination,corncob bedding D was higher than other 4 kinds(1.83%±0.2983%,P<0.05).In terms of moisture content,the moisture contents of the five kinds of corncob bedding were less than or equal to 10%.In the water absorption test,the water absorption capacities of the five kinds of bedding before autoclaving were all greater than 150%,and the water absorption of corncob bedding D after autoclaving was better than other four kinds(171.0±5.3,P<0.05).During microbial detection,the total number of colonies of corncob bedding B before autoclaving was higher than those of other four types(1.42×10^(5)±4.3×10^(4),P<0.05).The five kinds of commercial corncob bedding have different physical parameters and microbial conditions,and each has its own advantages and disadvantages.When purchasing and selecting corncob bedding,it is necessary to comprehensively consider the needs of daily feeding work,and choose bedding according to the effects on the health and welfare of experimental animals.[Conclusions]This study provides a reference for selecting suitable corncob bedding for mouse.
