The Effect of Large Versus Small End Up on Assigned Egg Grade

The Influence of the Position of the Eggs Upon Their Interior Quality

“…These results confirm those of Baker (1953) and substantiate the opinion of Dawson and Hall (1954) that the eggs placed small end up are judged as being of a worse quality grade because of the more visible yolk by candling.

“…The position of the egg also influences the visibility of the yolk in candling and therefore, also the candling grade quality, as has been already shown by Baker (1953). The yolk in the sac of the thick egg white is surrounded by the middle thin egg white which allows little movement of the yolk inside the egg.…”

“…Baker (1953) found, on the farms where the eggs were placed small end down, 69.7 percent of first grade eggs and, where the eggs were placed small end up, 72.7 percent of second grade eggs.
