Poultry disease patterns

In Algeria, the poultry sector is the animal production sector that has seen the most spectacular growth since the 1980s, thanks to government intervention (Alloui, 2011). According to the FAO (2009), poultry production in Algeria is the country's largest animal production sector. Developing this sector is the best way of meeting the population's growing need for animal protein as quickly as possible (Harkati et al., 2011). The aim of this document is to highlight the epidemiological situation of the main poultry diseases in the world, which will serve as a database for the various players in the sector, i.e. veterinarians, researchers, breeders and the authorities concerned.
