Abstract : Poultry feed has been reported to be of potential risk to the animals consuming it and as a matter of public health importance. The aim of this research was to determine the antibiotic susceptibility of organisms isolated from the feed samples sold in Ado Ekiti. Twelve feed samples of four different brands were analyzed. The results showed that the microbial load of the grower mash ranged from 2.8x103 to 1.9x106 CFU/g, layers mash ranged between 3.0x104 and 8.3x106 CFU/g while the broiler starter was found to be between 5.6x104 and 3.6x107CFU/g. Feed sample brand SBM have all time highest microbial load of 1.9x106, 8.3x106 and 3.6x107CFU/g for growers mash, layers mash and broiler starter respectively. The organisms isolated from the feed samples are Escherichia coli, Klebsiella sp, Salmonella sp, Pseudomonas sp, Bacillus sp and Staphylococcus aureus. The antibiotic susceptibility showed that Escherichia coli isolated from the poultry feeds have highest resistance to Amoxicillin/Clavulinate (AUG) with 91.7%, while Klebsiella sp, Salmonella Pseudomonas sp Bacillus sp and Staphylococcus aureus showed highest resistance to Cloxicillin (CXC) with 91.7%, 87.5%, 100%, 88.9% and 80% respectively. Gentamicin (GEN) had the best antimicrobial activity in this research with only 7.1 % of the organisms being resistant.
