Abstract :

   For comparison of the incidence rate of ascites in broilers affected by respiratory syndrome in Isfahan (ISF) and Chaharmaha-va-bakhtiari (CMB) provinces, 74 broiler chicken flocks in ISF and 27 broiler chicken flocks in CMB were monitored along growing period during 2010-2012. Results showed the frequency of ascites incidence in CMB was significantly higher than ISF (p<0.05). The analysis of data showed that there was a significant relationship between respiratory syndrome and ascites syndrome incidence in broiler chickens (p<0.05) but there was no relationship between ascites and location after respiratory syndrome. Furthermore, the percent of ascites incidence after respiratory syndrome in CMB was significantly higher than ISF (p<0.05). It seems that broiler chickens in CMB, due to some risk factors such as high altitude and low temperature, were highly susceptible to ascites after respiratory syndrome in comparison to ISF and it is necessary to apply specific nutritional and hygienic management measures of broiler flocks in this area.
