RESUMO

The last 30 decades were marked by an intensive poultry production, which reached a satisfactory level of production with the use of technology. These facts have allowed the country to stand out in a global setting, making the country the largest exporter and third largest producer of chicken meat in the world. Currently, projects related to rural equipment developed in Brazil have been studied only by Engineers and technicians, but could be optimized with the participation of Designers. This study aimed to compare three types of feeder for broiler chickens under the standpoint of management and preference of birds, examining the behavioral and duration of birds meals, and estimate the efficiency of the equipments. The evaluated feeders were: Tubular and Automatic, both currently marketed, and Fênix feeder, manual equipment proposed by a designer who is still undergoing tests. The study was conducted in a shed broiler commercial house that housed 14 thousand birds at a density of 16 birds m-2 at 17, 18, 20, 21, 23 and 24 days old. We used video footage to record the behavior and, based on these results and general knowledge on the subject, an assessment was preceded by the AHP (Analytic Hierarchy Process), to estimate the efficiency of each feeder in accordance with three distinct types of consumers: C1 (small producer), C2 (large producer) and C3 (researcher). The results indicate a bird s preference to the Tubular feeder, in which the behavior of "eating" and the time of meal were higher, and this is the only one that did not have a partition grid on the food plate, which may have been determinant to the birds preference. The Fênix feeder indicated that it was more appropriate to the consumer C1 and Automatic for consumers C2 and C3. The Tubular came in third place for the three consumers, even as the favorite for birds. The Fênix feeder presented compatible characteristics with competitors, been more efficient than the Tubular indicating, after some adjustments the ability to be manufactured
