本研究的目的是评估用于运输受精卵和日龄雏鸡的卡车的热分布。本研究在圣保罗州的肉鸡孵化场进行。试验进行了三个月，其中观察了6个鸡蛋负载和11个小鸡负载。在具有热控制和以下尺寸的环境控制卡车中进行热分布评估：蛋为7.5 x 2.6 x 2.5 m，小鸡为8.0 x 2.5 x 2.5 m。最大运输能力约为592箱鸡蛋和630箱小鸡，分布在卡车上。使用温度、相对湿度和比焓等热变量，以5分钟间隔对鸡蛋和10分钟间隔对雏鸡的热分布进行评估。地质统计学被用来模拟空间依赖性（克里金法）。结果表明，在卡车上的习服不足。负载被发现提交到一个不兼容的温度，显示了巨大的热变化的身体卡车。
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.
