Two hundred and forty day old broiler chicks were divided into four groups of 60 chicks each. Each group was further subdivided into three replicates of 20 chicks each.
Two experimental rations (starter and finisher) were prepared and fed to experimental chicks upto 50 days of age.
Virginiamycine, oxytetracycline and Furazolidone were mixed to experimental rations at the level of 10 mg/kg feed. The effects of these additives on weight gain, feed consumption, feed efficiency, mortality, weights of internal organs and residual effect on meat were recorded.
Feed and water were given libitum. Continuous light was provided for 24 hours.
The results revealed non-significant differences among weight gain, feed consumption and feed efficiency of the chicks fed on starter ration.
However the results obtained from 29-50 days showed significant difference (P <0.05) in weight gain, feed consumption and feed efficiency. The best weight gain was obtained with oxytetracycline supplementation followed by virginiamycine, furazolidone and the controlled group. Maximum feed was consumed by the birds fed on control ration. The best feed efficiency was noticed with birds fed on ration supplemented with oxytetracycline.
The results obtained from 0-50 days showed highly significant difference (P < 0.01) in weight gaiu of the birds. Feed consumption and feed efficiency also showed significant difference (P<0.05).
The maximum weight gain was noticed with birds fed on oxytetracycline supplementation followed by virginiamycine and furazolidone supplementation, while the least weight gain was shown by the birds fed on control ration.
Maximum feed was consumed by the birds fed on control ration and the least feed consumption was observed with birds fed on oxytetracycline supplementation followed by virginiamycine and furazolidone. The poor feed efficiency was observed with the birds fed on control ration.
Dressing percentage and weight of internal organs showed statistically non-significant.
The residual effect of antibiotics was not found in the chicken meat.
From the present study it was concluded that the addition of antibiotics in the broiler rations proved economical as compared to control.
