Abstract

Morbid materials from 25 commercial broiler breeder farms located in Abbottabad and Mansehra districts were collected over one year period to investigate prevalence of Fowl cholera and study efficiency of various organs to be used as diagnostic tools for fowl cholera. Overall incidence of Fowl cholera was (0.80?0.26%) with a coefficient of variation of 231.45%, indicating significantly higher incidence (1.07?0.62%) in Mansehra than in Abbottabad (0.53?0.34%). Significantly (p<0.05) lower incidence of Fowl cholera was found in vaccinated (0.15?0.26%) than in non-vaccinated flocks (1.45?0.63%). Higher incidence (1.35?0.38%) of Fowl cholera was found in farms previously exposed to Fowl cholera disease as compared to those in which there was no previous incidence (0.25?0.29%). Fowl cholera was found positively (p<0.01) and significantly associated with flock age (b=0.074661?0.03389) but negatively associated with egg production (b=-16.24429?0.928103). Liver was found to be the best organ for diagnosis of Fowl cholera in broiler breeder flocks.
