Reduced Yolk Color in Layers with Coccidiosis

Poultry Science, 1976
Abstract White Leghorn hens inoculated with 1,000,000 sporulated oocysts of Eimeria acervulina had lower egg production and lighter yolk color (as measured by N.E.P.A. value) than uninoculated controls. Plasma carotenoid levels were also reduced. Lighter infections with this upper intestinal species produced a decrease in yolk color even when egg ...

Color Measurement of Egg Yolks–An Instrumental Method

Poultry Science, 1977
Abstract A rapid, instrumental method of measuring egg yolk color for routine quality control is described. The method utilizes the Hunter D25 Color and Color Difference Meter, and is comparable in speed and accuracy to that of visual method. Egg yolks ranging in color from light yellow to red were obtained by incorporating crystalline lutein, β-apo ...
