Controlled egg production in poultry

Abstract

The profitability of the poultry industry is dependent on control of the onset of egg-laying in the pullet, and the timing and duration of the first moult. Manipulation of the environment—more particularly day-length—and control of nutrition can induce egg-laying and moulting at the economically preferred time. A new material, methallibure, offers an alternative method with the possibility of more precise control.
