Three experiments were conducted in which 3-week-old chickens were subjected to a handling procedure for 4 days (21 to 24 days of age) and subjected to heat stress on either the 5th or 7th day (25 or 27 days of age). The heat stress episode consisted of exposure to 50 C for up to 240 min in a forced-draft chamber. In two experiments in which broiler chickens were studied, the heat stress survival time, determined at 25 days of age, was increased by the handling procedure. The same phenomenon did not occur in Leghorn chicks or broiler chickens heat stressed after a 3-day adjustment period.
进行了三项实验，将3周龄的鸡在4天内（21至24日龄）进行一种处理程序，并在第5天或第7天（25或27日龄）使其遭受热应激。热应激过程包括在强制通风箱中暴露于50℃长达240分钟。在两项针对肉鸡的实验中，在25日龄时测定的热应激存活时间因处理程序而增加。在经过3天适应期后遭受热应激的来航鸡或肉鸡中未出现相同现象。
