This book is aimed at laying hen enthusiasts who have technical questions such as: which strains of hens to raise? How to build a henhouse? How to feed the hens? And what are the expected yields? We have chosen to divide the document into two main sections.In the first part, we look at the breeding of commercial laying hens, the characteristics of their housing, their nutrition, the main diseases and the sanitary prophylaxis that applies on a breeding farm.In the second part, we carried out a comparative study of the zootechnical performance of two strains of commercial laying hens (Lohmann Brown and Novogen Brown) from chick start-up to laying age. This second study was carried out on a PROLACAM farm in western Cameroon.
