Chapter synopsis:

This chapter reviews genetic selection to improve reproductive traits in chickens. The chapter begins by first focusing on the layer breeding programme structure, then moves on to discuss areas such as egg production, liveability, resilience and adaptability. It also examines how genetic selection can affect egg quality, nesting behaviour and various reproduction traits as well as hatchability, fertility and sperm quality. A section on the molecular tools used is also included.
