This study was conducted in the Bismillah Poultry Farm and Orkid Poultry Farm, Sreepur, Gazipur to evaluate efficacy of sulfadiazine and trimethoprim, and enrofloxacin against infectious coryza and pullorum disease in commercial layer birds. A total of 300 birds affected with infectious coryza in the Bismillah Poultry Farm were treated with two commercial preparations of sulfadiazine and trimethoprim, Ativet (Acme) and Trimsul 80/400 (DutchFarm). Four hundred birds affected with pullorum disease in the Orkid Poultry Farm were treated with two commercial preparations of enrofloxacin, Enrovet (Acme) and Komibiotril (Komipharm). In case of infectious coryza, subsidence of facial swelling, decrease in serous nasal exudates and purulent ocular discharge, decrease in sneezing and dyspnea were excellent within 5 days of treatment with both Ativet (Acme) and Trimsul 80/400 (DutchFarm), and the recovery rate was 93.3% and 92%, respectively. In case of pullorum disease, subsidence of whitish to yellowish diarrhea and reduction of drowsiness were excellent within 4 to 5 days of treatment with both the antibiotics, Enrovet (Acme) and Komibiotril (Komipharm). However, reduction of paleness of comb and wattle was not so excellent within 5 days of treatment. The recovery rate for Enrovet and Komibiotril was 92.5% and 94.5%, respectively.
