Title: Method for preventing urolith of water washing type stand for breeding experimental animal
Inventor: TAKEMURA EIJI
IPC: A01K1/01
Filed: 1992-05-19
Abstract: PURPOSE:To prevent the adhesion of urolith to a spout by adding an acidic material of a specific value or below into washing water and washing the spout. CONSTITUTION:The acidic material of PH <=5 more preferably PH <=4 is added into the washing water flushed at every specified hour in order to wash the excreta and urine of the experimental animals on the spout.
