The effects of ultrasonic treatment on eggshell microbial activity, hatchability, tibia mineral content and chick performance in Japanese quail eggs have been reported recently in the journal, Poultry Science, by A. Aygun of Selcuk University and D. Sert of Konya University.

A total of 600 fresh eggs was randomly divided into five groups. Treatments were no ultrasound, 35kHz for five minutes, 35kHz for 10 minutes, 35kHz for 15 minutes and eggs sprayed with benzalkonium chloride solution at 0.02 per cent (negative control).

Eggshell microbial activity was reduced significantly at all ultrasonic treatments (P<0.01).

There were no significant differences among treatments for egg weight loss, hatchability, embryonic mortality, chick weight, or tibia calcium, phosphorus, potassium, sodium and magnesium content.
