Transmission of poultry diseases and biosecurity in poultry production.

Abstract A review on the management aspects of poultry production with special focus on the spread of disease caused by horizontal and vertical transmission was discussed. This chapter also includes topics on: general biosecurity principles which includes geographical location of the poultry farm, structural layout of the poultry farm and buildings, potential sources of infection and operational flow on the farm, cleaning and disinfection protocols for poultry, and water quality in poultry houses; biosecurity aspects that are specific to the different production systems (broiler and layers); and biosecurity in hatcheries with focus on hatchery management from egg to chick, disease transmission in hatcheries, and hygiene and biosecurity in hatcheries.
