Abstract
Extract
One of the most important bases for grading a carcass is a knowledge of its age. However, under actual meatworks conditions, the exact date of birth of sheep that are delivered for slaughter is not known. The approved method for estimating the age in this species is by examination of the teeth, but the grader is unable to check the teeth because the head will have already been removed from the carcass as a part of the normal dressing procedure.
