Broiler farming in Malaysia use two type of housing systems namely close house and open house system. This paper has evaluated the economic impact of closed house system in broiler farm performance in Malaysia. An economic evaluation of 211 broiler farmers was conducted in three states in Peninsular Malaysia namely Perak, Pahang and Johor to determine the performance of the broiler farmers by using economic performance analysis. Pooled multiple regression model was used in the analysis. This model involves price per bird (PRM) as dependent variable and rearing housing system (DU), size of farm (SOF), feed conversion rate (FCR), average body weight(ABW), average marketing age (AMA) and mortality rate (MOR). The results show that all variables, except SOF, are significantly influence the performance of the farmers at five percent level of significance.
