Abstract

This study was conducted from July to October, 2020 to identify the level of microbiological
contaminations in feeds at the chicken farms in Dong Anh, Ha Noi. A total of 50 feed samples were
collected from 37 chicken farms for this study. The analyzed results showed that average total number
of aerobic bacteria in the testing samples was relatively high with the value of 4.96 ± 0.69 log10 (CFU/g),
ranged between 3.84 – 6.38 log10 (CFU/g). Mould was detected in 29 tested samples (58%) with the
average count was 2.65 ± 0.80 log10 (CFU/g), ranged between 2 – 4.25 log10 (CFU/g). In addition, the
total Coliforms of 24% tested samples were higher than the standard value, exceed 2 log10 (CFU/g).
