ABSTRACT

In order to evaluate the effect of ultrasonic use as rodent control, an experiment on Wistar rats under laboratory conditions was performed. Animals were divided in control- and experimental groups. The experimental group was exposed to a constant action of a device generator of ultrasonic waves during 12 weeks. The effect on reproductive performance of Wistar rats was evaluated through number of days from mate up to birth, number of alive pups at birth- and weaning age. In addition, effect of ultrasonic waves on younger ones, growth and development were also evaluated. Weekly weight gain was used as an indicator for the control- and experimental groups (P › 0.05), hence it can be concluded that ultrasonic waves generated by this specific device does not affect breeding performance and weight gain. Therefore, it seems not recommendable the use of such kind of devices as a control method against rodents.
