DIETARY EFFECT OF DIFFERENT ANTIBIOTICS AND DETECTION OF ANTIBIOTICS RESIDUE IN THE MEAT OF SONALI CHICKEN IN BANGLADESH

Abstract

This study was conducted to evaluate the efficacy of various antibiotics on production performance, dressing yield and detection of antibiotic residue in the meat of Sonali Chicken in Bangladesh. For this purpose, a total of 120 day old chicks were randomly assigned into four treatment groups namely T0, T1, T2 and T3 having three replications in each treatment group. Chicks were brooded upto 7 days then randomly separate into replication wise in separate pen for rearing 9 weeks. Each treatment group contains 30 birds whereas each replication contains 10 birds. Experimental birds in T1, T2 and T3 were provided ciprofloxacin @ 1ml, oxytetracycline @ 1gm and amoxicillin @ 1gm per liter respectively drinking water while T0 was provided only plain water and T0 was maintained as control group. The results of this study indicated that final live weight gain and feed efficiency of birds were insignificantly (P>0.05) higher in T2 group and T1 group compared to T0 group. In case of meat yield parameters, there were no significant difference among the treatment groups. Antibiotic residue was the highest in T3 group in meat. But antibiotic residue was nil in liver in T3 group. On the other hand, T2 group found with antibiotic residue in both meat and liver. In T1 group, there were no antibiotic residue in both meat and liver. Based on the result it could be concluded that the supplementation of different antibiotics, oxytetracycline @ 1gm/L drinking water has potential effect on growth performance and kept as antibiotic residue in both meat and liver of Sonali chicken in Bangladesh.
