Abstract

The study was carried out to elaborate response surface models through broiler performance data recovered from literature in order to predict performance and develop economic analysis. Three hundred and twenty eight studies published between 2005 and 2009 were retrieved using the systematic review of literature method. Average weight gain and feed intake data were collected from twelve studies that fulfilled the preestablished inclusion criteria, and response surface models were adjusted with metabolizable energy, environmental temperature, and slaughter age as independent variables. The models for weight gain (R²=0.88) and feed conversion (R²=0.87) were accurate, precise, and not biased. There was no interaction between metabolizable energy and environmental temperature on weight gain and feed intake. The independent variables age and temperature showed interaction for weight gain and feed conversion, whereas the interaction between age and metabolizable energy was detected only for weight gain. It was possible to elaborate economic analysis to determine maximum profit, as a function of the variables included in the model, in different market situations determined by changes in broiler and feed prices. Response surface models are effective to predict broiler chickens performance and allow the development of economic analysis to optimize profitability according to market prices.
