In this paper, air bacteria content were detected before and after disinfection with natural sedimentation in scale lactating dairy cowshed, mastitis investigation and isolation and identification of pathogenic bacteria were also done. The results showed that there has different outcome in different cowshed, as well as in different mediums. NA medium has colonies of up to 77.8×103cfu/m3, SS medium has no bacterial growth in a number of distribution points. Cowshed environments has a substantial reduction in the number of bacteria of the air after Disinfection, while the number of bacteria in the air of sports ground was significantly lower than those in cowshed. Cow mastitis occurrence and the total number of airborne bacteria of cowshed environment was positively correlated. The more bacteria, the high occurrence of cow mastitis in the cowshed. Staphylococcus aureus, E. coli, Salmonella typhi, Klebsiella pneumoniae bacteria were isolated from both mastitis milk and ambient air.
