摘　　要：布氏田鼠冬季依赖储存在仓库中的牧草越冬,然而对布氏田鼠在秋季储食期对不同大小的食物的选择嗜好却没有研究报道.2012年秋季在内蒙古锡林郭勒盟典型草原区,研究了布氏田鼠秋季储草期对不同颗粒大小的食物的储食选择.为保证食物质地的均一性,从锡林浩特市场上采购了不同规格大小的玉米或者玉米碴为材料,由大到小分别设置整粒玉米、大号玉米碴、中号玉米碴、小号玉米碴和玉米粉等5种不同大小的颗粒,作为布氏田鼠的选储材料.选取了挖仓行为表现较好的布氏田鼠越冬洞群6个,采用固定铁盘放置大号玻璃培养皿,将5种不同规格的玉米颗粒同时放置在铁盘上,同时依次轮换不同规格玉米颗粒的培养皿在在选储盘上的位置,研究结果表明:颗粒大小不同显著地影响布氏田鼠的选储嗜好,其选择偏好顺序为:大玉米碴→中玉米碴→小玉米碴→整粒玉米→玉米粉.布氏田鼠偏好喜欢大型的食物颗粒,对大玉米碴的选储偏好最强,而对玉米粉很少取食,但对体积最大的整粒玉米的衔叼能力比较弱,这可能跟布氏田鼠的搬运能力有关.Brandt＇s vole cover winters with the forage stored in the warehouse, but the food-storing-preference of the voles for the different sizes has not been reported. We studied the food-storing-preference of the Brandt＇ s of different sizes corns at Xilin Gol League in Inner Mongolia typical steppe in 2012. In order to ensure uniformity of texture of food , we purchased different sizes corn from whole corn , large corn ballast , medium corn ballast , trumpet corn and corn powder as Brandt＇ s vole selected storage material from Xilinhot market. We selected 6 better behaved wintering caverns and the five kinds of different corn were placed on the large glass dishes in the iron plate and the position of the dishes were changed in turns. The results showed that： the particle size significantly affects Brandt＇ s vole select preference, their order of preference was large corn ballast →medium corn ballast →trumpet corn →whole corn →corn powder. Brandt＇ s voles prefer large food particles , large corn ballast was strongest prefered while rarely feeding on corn powder. But the result shows the whole corn were also rarely chose, which may be restricted by Brandt＇ s handling capacity.

关 键 词：布氏田鼠 食物大小规格 储食期 食物选择偏好.
