Abstract
In 3 trials with laying hens the influence of the kind and the amount of feed lipids on the incorporation of canthaxanthin and the vitamins A and E from feed into egg yolk has been studied. In the first experiment canthaxanthin and the vitamins A and E were added in increasing amounts to the basal ration, which contained only very low quantities of fat and vitamins. In the second and the third experiment vitamin and canthaxanthin contents in the ration were held constant but the amount (second experiment) and the type (third experiment) of feed lipids were varied.
