【 摘 要 】

The aim of this study was to evaluate the thermal profiles of trucks used for transporting fertile eggs and day-old chicks. This study was carried out in a broiler hatchery in the State of Sao Paulo. The experiment was conducted during three months, in which six egg loads and 11 chick loads were observed. Thermal profile assessments were performed in an environmental controlled trucks with thermal control and following dimensions: 7.5 x 2.6 x 2.5 m for eggs, and 8.0 x 2.5 x 2.5 m for chicks. The maximum transport capacities were approximately of 592 boxes of eggs and 630 boxes of chicks, distributed all over the lorry. The thermal profiles were assessed at five-minutes-interval for eggs and in ten-minutes-interval for chicks, using thermal variables such as temperature, relative humidity and specific enthalpy. Geostatistics was used to model spatial dependency (by kriging). The results showed that the acclimatization in trucks was deficient. The loads were found to be submitted to an incompatible temperature, showing a huge thermal variety in the body trucks.
