摘要

This manual is an aid in teaching both beginning and experienced egg graders thecorrect interpretation and application of the U.S. standards, grades, and weight classes for eggs. It can serve as a guide in short courses or grading schools when supplemented with lectures, group discussions, and demonstrations. This manual should also prove useful to those teaching or working in the production, processing, and marketing of eggs. Although some of the material in this manual is not directly related to the actual grading function, knowledge of it will help graders do a better job in handling eggs and in maintaining egg quality. Such information will give graders a better understanding of their job, and will aid them in acquiring the knowledge necessary to do their jobs well.
