EPIDEMIOLOGICAL INVESTIGATION OF PASTEURELLA MULTOCIDA INFECTION IN POULTRY IN GAZIPUR DISTRICT OF BANGLADESH

Abstract

The present study was undertaken to determine the present status of fowl cholera (FC) infection of poultry in Gazipur district during September 2016 to February 2017. A total of 282 either dead or sick birds (Layer and Sonali) were taken as sample in which the sick birds were subjected to record clinical data and consequently the dead birds were for post mortem examination. Hence, overall 12.41% prevalence was found for FC and about 87.59% was for mixed other diseases.  All the birds were grouped into six named as A1, A2 and up to A6 accordingly their age. The highest incidence (29.79 %) was found in A1 (8-20weeks) group and the lowest was 4.26% in A5 (51-60 weeks) group. Furthermore, six FC infected farms were categorized to treat with six specific antibiotics individually. Thereafter, the highest recovery rate (89.6% and 87.5%) was recorded in two farms using Enrofloxacin and Gentamicin particularly. The lowest recovery rate (60%) was in Erythromycin treatment group. However, the layer birds of six farms lost their body weight almost 11.84%, specifically the highest percentages (16.49%) was in treated with Ampicillin and lowest percentages (5.79%) found in a farm treated with Gentamicin. In brief, FC commonly appears just near to laying age and therapeutic management trivially decreases the body weight that ultimately shoots up the production cost.
