| Abstract: | Ultrasound emission is a method used to eliminate rats from buildings. This study was aimed at establishing whether immediate and strong behavioural reactions could be noticed in farm animals when exposed to ultrasonic sound from a device used for rat eradication.Behavioural reactions were recorded in horses, cattle, swine, sheep and poultry. The character of the behaviour reactions observed suggests that the animals experienced the pulsating ultrasound as a disturbance. It is concluded that ultrasound can not be regarded as suitable for rat eradication in stables for horses, cattle, sheep, swine or laying hens. |
