              Abstract
              
              
                
                The presence 
                of microorganisms in the hatchery is directly related to 
                deficiencies in hygiene, which can result in elevated first-week 
                chick mortality and depressed growth rate. Bacteriological 
                analyses of the air in two broiler hatcheries in the province of 
                Constantine (North-East of Algeria) showed that their hygienic 
                levels remain insufficient with high contamination rates and the 
                presence of a large number of highly pathogenic bacteria 
                including Salmonella spp, E. coli, Pseudomonas 
                aeruginosa and Staphylococcus aureus.
