Seasonal Changes in Interior Egg Quality of Single Comb White Leghorn Hens

CONSIDERABLE effort has been expended in recent years to discover just what quality is in reference to the contents of an egg, to set up and to standardize ways of improving and maintaining it at a high level. But there has been little work to show differences in the initial quality of eggs, as determined by present day measures, that occur with season. Parker, Grossman and Lippincott (1926) concluded that there is no seasonal effect on the color of the yolks of eggs. Almquist (1933) states that, “eggs are not all ‘created equal’ or, if they are, they do not long remain so. Initial quality and keeping quality may vary greatly from egg to egg, but are found to vary to a relatively small extent in eggs from the same hen.” This paper considers the seasonal changes in the interior quality of eggs laid by a flock of S.C.
