林文助.1989.野鼠取食量之探討。台南區農業改良場研究彙報23:91~97。

台灣田間五種主要野鼠為鬼鼠(Bandico ta nemorirage Hodgson)、溝鼠(Rattus norvegicus Erxlebem)、小黃腹鼠(Rattus losea Swinhoe)、赤背條鼠(Apodemus agrarius)及月鼠(Mus formosanus Kuroda)。台南場於76年3月至77年1月,在室內進行糙米飼養及調查工作,並將糙米以每公斤新台幣16元計算,得知每頭野鼠平均每天取食量及消耗值為:鬼鼠40.5公克,值0.65元。溝鼠31.8公克,值0.51元。小黃腹鼠13.5公克,值0.22元。赤背條鼠6.7公克,值0.11元及月鼠3.2公克,值0.05元。五種鼠類每天平均取食量為19.1公克,值0.31元,在室內專供糙米換算年消耗值平均每頭野鼠為113.15元。


Studies on the Eating Amount of Rats in Taiwan

Summary

Bandicota nemoriraga Hodgson, Rattus norvegicus Erxlelem, Rattus losea Swinhoe, Apodemus agrarius Pallas, and Mus formosanus Kuroda are the main species of rats in Taiwan.  In order to investigate the eating amount of a rat per day and to estimate the loss its caused, studies were conducted at Tainan DAIS from March 1987 to January 1988.  Brown rice was used as a feeding material.  The eating amount of a rat per day was investigated; the value was transferred into New Taiwan dollars.  One kilograms of brown rice was set up at 16 dollars in this experiment.  The results indicated that the eating amount of a rat per day and its cost were estimated at 40.5 g and 0.65 dollar, respectively, for B. nemoriraga; 31.8 g and 0.51 dollar for R. norvegicus; 13.5 g and 0.22 dollar for R. losea; 6.7 g and 0.11 dollar for A. agrarius; and 3.2 g and 0.05 dollar for M. formosanus.  Overall mean of the five species, the eating amount and loss by a rat per day were estimated at 19.1 g of brown rice and 0.31 dollar, respectively.  The annual loss caused by a rat was estimated at 113.15 dollars.
