These data were include manager education, manager experience, technical manager experience, workers experience, one-day-old chicken weight, the interval between two sequential rearing period, vaccination against the widespread disease, feed quality, feed additives, farm and vehicle disinfection, mortality and collecting form of death chicks. Data were analyzed by SPSS 20 software package.The ANOVA results showed that all factors except vaccination against the Gambro disease and one-d-old chick weight have no significant effect on mortality. Day-old chicks with more than 42g body weight have lower mortality rate rather than those have -42g weight at d 1. Usual mortality in farms where their chicks vaccinated against Gambro were lowers than those no vaccinated chicks. Therefore, it can be concluded that the reduction of the daily losses in poultry meat among the factors evaluated personal factors and factors of diet and health are very important.
