Evaluation of the effects of enrofloxacin and some feed additives on the performance of broiler chicks

Abstract EN

The present study was conducted to compare between the effects of probiotic and some antibiotics as enramycin and enrofloxacin on the broiler performance.

The experiment was carried out on 600 one day old chicks divided into six groups each contain 100 chicks.

The chicks were reared in separated blocks, provided with wood shaving litter, plastic feeders and water troughs.

The birds were fed on a starter ration for the first three weeks and then on a grower ration for the next three weeks and the water was provided ad libitum.

The average feed intake, body weight, weight gain, feed conversion ratio and feed efficiency were measured.

The results showed that all treated groups showed lower feed intake than the control group except enrofloxacin treated birds showed higher feed intake than the control group.

In the same time all treated birds revealed higher body weight, weight gain, organs and carcass weights except enrofloxacin treated birds which showed lower levels than the control group.

Feed efficiency and feed conversion ratio were more efficient in all treated birds except that of enrofloxacin treated birds which were less efficient than the control and treated groups.
