A total of 600 fresh eggs was randomly divided into 5 groups. Treatments were no ultrasound, 35 kHz for 5 min, 35 kHz for 10 min, 35 kHz for 15 min, and eggs sprayed with benzalkonium chloride solution at 0.02% ( negative control). The 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 Ca, P, K, Na, and Mg content.en10.3382/ps.2011-01901info:eu-repo/semantics/openAccessultrasonic treatmenteggshell microbial activityhatchabilitychick performanceArticle91373273822334750Q1WOS:000300616800023Q1
