Abstract
Eggs from hens that received a choline-deficient basal diet with or without additional methionine, vitamin B12, or choline supplements for a period of 50-60 weeks were analyzed for fat and choline. Choline deficiency in the hen resulted in smaller eggs and reduced concentration of fat (ether extract) and choline in the egg. Supplementations of choline or vitamin B12 markedly increased egg size, choline and fat concentrations. Methionine increased yolk size, choline and fat concentrations, but had no effect on egg size.Keywords
