  To reduce the losses caused by the E. coli, antimicrobials widely used in the poultry industry. The aim of this study was to compare pulse and continues administration of the Enrofloxacin on the performance and biochemical parameters were caused by colibacillosis. Four hundred and fifty colibacillosis infected broiler chickens was selected and distributed in 3 groups of 150 chicks and each with 3 replicates. In the first group Enrofloxacin was administrated 4 days continuously and in the second group it was administrated by pulse method 4 days and daily 8 hours and third group was as control. After treatment, 21 blood samples were taken from each groups, and by biochemical tests, the amounts of ALT, AST, total protein, ALP and creatinine was evaluated. White blood cells differentiated amount also were recorded. Gross lesions and clinical signs also evaluated during study period. For comparison the results Independent T-test and SPSS statistical software ver. 22.0 were used. Results indicated there was significant differences between the methods from AST and ALT aspect(p<0.05). The results indicated that WBCs and heterophils were decreased in continues group (p<0.05). Lymphocyte, Monocyte and Hematocrit was not different statistically between groups (p>0.05). It was demonstrated that the pulse administration of Enrofloxacin has better outcomes in treatment of colibacillosis and also it was decreased costs of antibiotics usage in poultry production. Thus pulse administration suggested for treatment of colibacillosis. Manuscript profile

  Escherichia coli is one of the most important causes of infection in avian species. To reduce the losses caused by this organism, antimicrobials are widely used in the poultry industry. The aim of this study was to compare pulse and continues administration of doxycycline on the clinical signs, lesions and selected biochemical parameters in colibacillosis infected broilers. The study was performed in a colibacillosis infected broiler farm with two similar houses. In the first group Doxycycline was administrated continuously for 4 days and in the second group it was administrated by pulse method for 4 days and 8 hours daily. After treatment, 20 blood samples were taken from each group, and the amounts of ALT, AST, ALP, total protein and creatinine was evaluated by biochemical tests. Differentiated white blood cell counts were also recorded along with gross lesions and clinical signs. Results indicated that there was a significant difference between the two methods concerning the amounts of AST (p<0.05). Although the amounts of ALT, ALP and creatinine in the continuous group were lower than pulse group, but it was not statistically significant. In the continuous group, WBCs and lymphocytes decreased significantly (p<0.05) while hematocrit, heterophils and eosinophil increased significantly (p<0.05). It was demonstrated that the pulse administration of doxycycline had better outcome in treatment of colibacillosis in comparison to continuous administration. Conflict of interest: None declared.
