ABSTRACT

Wrong used of antibiotics have the tendency or inclination to deposit some residues in the tissues of animals for human consumption. This research was undertaken to look into the importance and presence of antibiotic residues in poultry meat in Maiduguri. One hundred and fifty-five samples of poultry meat were collected from various poultry slaughter units. Five grams of each sample was subjected to thin layer chromatography for detection of antibiotic residues. The samples were crushed and squeezed in 5ml of ethanol. They were clarified by centrifuging the solvent and evaporated completely using water bath. They were later loaded and run on silica gel plates and developed by putting in developing tank containing 50ml of methanol and acetone. This was lastly put in the iodine tank for chromatography to be developed for observation. The results showed that 21 (13.54%) of the samples were positive for oxytetracycline while 3 (1.93%) of them were positive for procaine penicillin. In conclusion, antibiotic residues are common in hybrid birds; proper attention should be given to the breed in terms of management. It is recommended that the use of antibiotics should follow withdrawal period in relation to marketing period. Proper professionals should be employed to handle the administration of antibiotics to birds.
