Abstract

One of the factors may affect the productivity and economic index of broiler industry is the mortality at the end of the growth period. The purpose of this study was to investigate the rate of mortality in broiler chickens and the management parameters. For this purpose, the management information of 30 poultry farms from 1396 and 1397 was collected. Using logistics analysis, the effect of various factors on the mortality rate was investigated. Our results showed that the effects of all factors examined in this model were positive, which were not significant for the factors of breeding season, building type, experience of managers, and biosecurity level, despite their importance in loss percentage. The results of this study showed that management parameters have key role in the mortality rate and consequently economic productivity of a broiler farm.
