Some Physical and Chemical Properties of Eggs from Hens of Five Different Stocks

Abstract

RESEARCH reports dealing with the influence of breed or strain of laying hens on the amount and composition of various egg components have appeared frequently in the literature in the past decade. Hens from different stocks have been shown to produce eggs differing in moisture and protein (Cotterill and Winter, 1954; May and Stadelman, 1960). It has also been reported that hens from different breeds or strains produced eggs differing in total lipids and fatty acid composition (Edwards et al., 1960; Edwards, 1964). There is a possibility that part of these differences which have been attributed to genetic influence may have been only a reflection of egg weight since it has been shown that part of the variation in level of egg components between different stocks is only a reflection of change in egg size (Scott and Warren, 1941; Marion et al., 1964). This report is concerned with observations…
