Unimportance of yolk loss in the egg as a factor limiting egg production in the domestic hen

Abstract
The injection of yolk material into the body cavity to replace that lost in the egg did not increase the rate of oviposition. During the first few weeks of this procedure a drop of 18 per cent in the rate of laying was observed. It was concluded that the loss of material in the formation of yolk is not a limitation to subsequent ovarian activity.
