Comparação zootécnica e econômica da produção integrada de frangos de corte em diferentes sistemas de climatização

Abstract

The objective was to compare zootechnical and economic indicators obtained in the production of broiler chickens reared in climatic systems by positive pressure and negative pressure. Multiple case studies were used to determine which of the air conditioning systems is the most advantageous alternative for the production of broiler chickens under integration contracts. Financial and zootechnical data were collected for 18 months, at each production cycle, in six properties located in the city of Prados - MG. Economic analyzes were performed based on the average of 21 production cycles for each air conditioning technology, making a total of 42 lots evaluated in the research. The results showed that the negative pressure air conditioning system presented better zootechnical and economic indicators than those obtained by the use of positive pressure sheds. Considering the total revenue obtained from the activity, the use of negative pressure sheds generated economic profit for the producers that chose to build under this technology of air conditioning. On the other hand, the remuneration obtained from the use of positive pressure was sufficient only to equal the total revenue with the total cost of production.
