The acclimatization of poultry to a hot, dry climate was assessed by studying changes in rectal temperature (Tr) during regular daily exposure to an ambient temperature of 38 degrees C and 26% RH. Laying hens of two strains, young chicks, growing broilers and broiler breeders were able to acclimatise, in varying degrees, to these conditions. Acclimatization was characterised by a progressive reduction in the rate of increase in Tr over the period of exposure and the ability to survive conditions that initially would have been fatal. Laying hens could acclimatise if prevented from displaying their normal postural responses to heat stress. Acclimatization was accompanied by a decrease in oxygen consumption when measured at either the acclimatization temperature or at a thermoneutral temperature.
通过研究家禽在每日定期暴露于38摄氏度环境温度和26%相对湿度（RH）条件下直肠温度（Tr）的变化，评估家禽对炎热干燥气候的适应性。两种品系的蛋鸡、雏鸡、生长中的肉鸡和肉种鸡都能够在不同程度上适应这些条件。适应性的特征是在暴露期间Tr的上升速率逐渐降低，以及能够在最初可能致命的条件下存活。如果阻止蛋鸡表现出它们对热应激的正常姿势反应，它们就可以适应。在适应温度或热中性温度下测量时，适应伴随着氧气消耗的减少。
