Studies on the Cholesterol Content of Eggs from Various Breeds and/or Strains of Chickens

LIMITED information is available on the effects of breed or inheritance on cholesterol content of eggs. Harris and Wilcox (1958) reported that the cholesterol content in the yolk of eggs from hens representing the 1957 Cornell Random Bred White Leghorns was quite uniform. The cholesterol values of these hens did not differ significantly during the various periods of the year. However, cholesterol value differences were found between daughters within dams and dams within sires. Significant positive correlations were obtained from the cholesterol values of eggs laid by the same hen whether the eggs were taken over a large time interval (5 months) or from two eggs laid during the same period. No information has been found on the cholesterol content of the eggs from various strains of chickens. The object of the experiment reported here was to investigate the cholesterol content of the eggs from a number of strains of …
