PROBLEM TO BE SOLVED: To improve safety in comparison with a case of using calcium hydroxide in itself.SOLUTION: Disinfectant containing slug is scattered on ground such as around cattle shed, in the cattle shed and outside edge of farm (S1). The scattered granular disinfectant is stamped by a person or a vehicle, and is cracked or crushed (S2). The cracked or crushed disinfectant sticks to the person or the vehicle which have cracked or crushed the granule, and moves with the person or the vehicle (S3). Whether the disinfection effect of the disinfectant decreased can be detected by checking with viewing whether the disinfectant becomes purple (S4). When the decrease of the disinfection effect of the disinfectant is detected, the disinfectant is scattered again (S5).SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】水酸化カルシウム自体を使用したときと比較して安全性が高い。【解決手段】スラグを含有した消毒剤を、畜舎周辺、畜舎内、農場外縁部等の地面に散布する(S1)。散布された粒状体の消毒剤を人又は車両によって踏み潰して解砕又は粉砕する(S2)。粒状体を解砕又は粉砕した人又は車両等に付着した消毒剤の解砕物又は粉砕物が、人又は車両等と共に移動する(S3)。消毒剤が紫色に変化しているか否かを目視で確認することで、本消毒剤の消毒効果が低下したか否かを検出できる(S4)。本消毒剤の消毒効果が低下したことを検出した場合、本消毒剤を再散布する(S5)。【選択図】図1
