SUMMARY:

Brazilian poultry farming stands out for its integration system, competitiveness and increasing incorporation of high-level technology in its farms. The aim of this study was to compare the zootechnical and economic results between two broiler housing technologies, the conventional (positive ventilation) and the fully automaticclimate control system (negative ventilation), and. determine which is the most sustainable one. Statistical analysis was performed on a database of 20,443 flocks of heavy broilers, from an agroindustry in eight regions of Brazil during 2020 and 2021. For the zootechnical evaluation, the response variables considered were feed conversion, average live weight , total and partial condemnation of the carcasses, and total mortality. For the economic evaluation, the annual production costs of each technology were calculated, considering the following items with the greatest impact: food, labor, electricity, firewood for heating, depreciation of invested capital and maintenance of facilities and equipment. The effect of the type of technology was significant in the evaluated zootechnical variables, and the adjusted averages were always favorable to the automatic climate control housing system. The total cost per ton of product delivered, after deducting losses due to total and partial condemnations, also indicated an economic advantage of the automatic systems. In conclusion, we have greater economic sustainability for the production of broilers in the fully automatic climate controle houses, both from the point of view of producers and the industry.
