MetadataShow full item record
The study is realised in 08 avian production unities (05 broiler houses, 01 breeders house and 02 hatcheries) in the Wilaya of Constantine. The aim was to determine the microbial contamination level (specially bacterial contamination : total flora, staphylococcus, enterobacteria and salmonella) of the air and the surfaces of each unity before and after cleaning and disinfection and establishing a critical analysis of the different biosecurity measures taken in them. A total of 1194 bacterial enumerations and more than 340 searches for salmonella have been realised.
