Limited information is available on suitable height of transport crates for turkeys. We compared behaviors and physiological indicators of four groups of 10 female turkeys each confined in either conventional (38.5 cm height) or experimental (77 cm height) crates during six commercial pre-slaughter transportations for 86 km (76 ± 4 min) along two tracts with one-lane streets, crossroads, bends, roundabouts (S1 and S2) and a highway tract (H) between S1 and S2. Only 36% of birds in the higher crates maintained a standing position. In conventional versus experimental crates, the frequency of rising attempts was five/bird/hour versus less than one/bird/hour, while wing flapping was seven/bird/hour versus 20/bird/hour, and balance loss was one versus four/bird/hour. The behaviors of both groups differed significantly according to the route tract, with a lower frequency of stress-related behaviors at H. No scratches, fractures or hematomas were detected in any birds after transportation. Crate height had no significant effect on hemato-biochemical markers. These results suggest that crates enabling a standing position may increase potentially dangerous behaviors. Moreover, busy and curvy routes should be avoided, as they may contribute to increasing the frequency of stress-related behaviors.
关于适合火鸡运输笼的高度，目前可用信息有限。我们比较了四组每组10只雌性火鸡的行为和生理指标，在沿着两条单行道街道、十字路口、弯道、环形交叉路口（S1和S2）以及S1和S2之间的高速公路路段（H）进行的6次商业屠宰前86公里（76±4分钟）运输过程中，这些火鸡分别被关在传统高度（38.5厘米）或实验高度（77厘米）的笼子里。在较高笼子里只有36%的火鸡保持站立姿势。在传统笼子与实验笼子中，起身尝试的频率分别是每只火鸡每小时5次和每只火鸡每小时不到1次，而扑打翅膀的频率分别是每只火鸡每小时7次和每只火鸡每小时20次，失去平衡的频率分别是每只火鸡每小时1次和每只火鸡每小时4次。两组火鸡的行为根据路线区域有显著差异，在高速公路路段（H）压力相关行为的频率较低。运输后在任何火鸡身上均未检测到抓伤、骨折或血肿。笼子高度对血液生化指标没有显著影响。这些结果表明，能让火鸡站立的笼子可能会增加潜在危险行为。此外，应避免繁忙和弯曲的路线，因为它们可能会导致压力相关行为的频率增加。
