SUMMARY:

The objective of this research was to evaluate the microclimate within the transport crates of commercial loads of broilers on different distances from the farms to the slaughterhouse in the summer period and its influence on the mortality of birds to the industry platform. Thirty loads of heavy broilers were evaluated using 9 dataloggers at equidistant points in the truck load to record the internal temperature and humidity every 10 minutes. The experiment followed a descriptive statistical analysis. After verifying the normality of data distribution, they were submitted to analysis of variance with subsequent comparison of means by Tukey's test or DSCF. There was not significant difference among the mapped points of the loads, the distances of the paths or the mortality of the broilers. It was observed that the first boxes positioned behind the truck cabin presented high levels of humidity in the group of shorter distances. This creat a point of attention to the practice of wetting the load, which if used improperly can cause the opposite effect and cause stress on broilers, due to high formation and low moisture dissipation. The wind dynamics along the transport has a fundamental role on the formation of microclimates in the loads. This variable may be considered an aggravating factor in cases of stress and causing productive losses, including the mortality of animals in transport. This result opens the door to reviewing loading management related to the wetting of loads.
