INTRODUCTION
Many years of genetic research have developed layers with excellent production traits like live ability, production and egg quality. These highly favourable genetic characteristics can only be fully realized when the bird is provided with good management, which includes, but is not limited to, good quality feed, housing and proper management practice. The purpose of this managementguide is to help the producer to gain the best possible results for their investment. This will be achieved by providing conditions in which the layers can thrive. The information supplied in this publication is based on the analysis of extensive research and field results, produced over time and with many years of experience. We do recognize that over time, many egg producers have developedtheir own management program, based on specific housing types, climate, feed, market conditions and other factors. These individual management techniques will also be the result of experience and many of these techniques will work for our layers as well. Therefore do not hesitate to use your own experience in conjunction with the guidelines in this guide. And of course, do not hesitate to consult ourdistributor who will be happy to help in any way they can.

Rearing period:
Goodbrooding conditions for the best starting of the chicks
The period from one day old to the point of first egg production is a critical time in the life of the laying hen. It is during this time that the physiological capability of the hen is developed. Success in the rearing period leads to the success in the laying house and it starts from chick arrival. All the standards and programs set forth inthis section have been proven to give excellent performances in production. Any delay in growth at 4-5 weeks will be reflected in a reduction in bodyweight at 16 weeks and then in performance, particularly in mean egg weight in temperate climates or a delay in start of lay in hot climates near the Equator.
