Effect of Dietary Choline, Methionine, and Vit. B12 on Weight and Composition of Eggs.
Summary Choline deficiency in the laying hen resulted in smaller eggs and reduced concentration of fat (ether extract) and choline in the egg. Supplementations of choline or vit. B12 markedly increased egg size, choline and fat concentrations. Methionine increased yolk size, choline and fat concentr...

Zusammenfassung: | Summary
Choline deficiency in the laying hen resulted in smaller eggs and reduced concentration of fat (ether extract) and choline in the egg. Supplementations of choline or vit. B12 markedly increased egg size, choline and fat concentrations. Methionine increased yolk size, choline and fat concentrations but had no effect on egg size. |
