Abstract

The city of Bastos, SP, is the largest producer of eggs in Brazil. This condition was achieved after several decades of development of production systems, commercialization and organization. About the advances in the production system includes the development of laying houses, which it is also noted various types in operation. The objective of this work is to achieve a precise tracking of the environment and the productive and economic losses from three warehouses of commercial laying hens, which are different in the housing system (pyramidal or vertical) and the presence of air-conditioning (forced ventilation or ventilation of tunnel negative) by identifying which of these warehouses have greater scope to contribute to the producer. It is hoped with this work to relate changes in thermal environment to the production losses, and identify what type of production system is most appropriate for the region of Bastos, in terms of the margin of contribution for the producer.
