This study aims to evaluate the biochemical and microbial quality of poultry feeds in farms of the Abidjan district. Thus, 164 samples of industrial feeds and farmer-formulated feeds were collected in Bingerville, Yopougon, Port-Bouet, Anyama and Songon areas for microbiological and biochemical analysis. The microbiological analysis consisted of isolation and identification of bacterial and fongical flora potentially pathogenic for the animal. The biochemical analysis was aimed to evaluate the nutritional composition of these feeds. Results showed that among these samples, 15 (10.33%), 91 (55.48%) and 48 (29.26%) were positive respectively for Salmonella sp., E. coli and Aspergillus sp. Moreover, biochemical analysis showed low feeds moisture rate levels ranging from 7.52 ± 0.16% to 12.14 ± 0.05%. Feeds formulated by farmers had low content in ash, protein and lipid with proportions ranging from 4.30 ± 0.15% to 11.61 ± 0.24%, 9.30 ± 0.24% to 15.81 ± 0.20% and 2.07 ± 0.02% to 3.68 ± 0.11% respectively when compared to commercial feeds. In conclusion, the study shows a poor hygienic quality of the feeds used in modern poultry husbandry in the Abidjan district. However, the content of analyzed feeds content are mostly in conformity with the recommended standards.
