Includes bibliographical references (pages 11-14). "Ultrasonic measurements Were found to be correlated with shell thickness (r = 0.424) and with the force required to fracture the shell under quasi-static compression (r = 0.203) based on readings from 84 eggs. If 6 eggs which were at the extremes Were eliminated from the data, the coefficients increased to 0 .82 and 0.43 respectively. Thus, it would appear that ultrasonic measurements may have potential for predicting shell thickness and strength non-destructively. It was concluded that additional testing and development is worthwhile when more precise equipment becomes available"--Summary, page 1. Egg trade Canada. Œufs Commerce Canada. Canada.
