众所周知，粉尘浴是由随着时间的推移而积累的内部因素和外部因素（例如看到灰尘基底）之间的复杂相互作用引起的。在这项研究中，其他外部因素的影响进行了调查。环境温度是重要的，当母鸡被关押在22比在10摄氏度（P < 0.01）的尘浴的频率更大。在第二个实验中，辐射热源或辐射热+光源，平衡以提供相同的辐射热，导致更多的尘浴行为在1小时的刺激期间比在同一时期没有刺激（P < 0.05）。热+光刺激使尘浴中各组分含量显著增加（P < 0.03）。在第三个实验中，单独的母鸡在笼子里进行dustbaths的量增加了一组母鸡dustbaths在相邻的笔与dustbaths相比，发生的量时，母鸡缺席的笔。(C)1998 Elsevier Science B.V.保留所有权利。
Dustbathing is known to be motivated by complex interactions between internal factors which build up over time and external factors, such as the sight of a dusty substrate. In this study, the effects of other external factors were investigated. Environmental temperature was shown to be important; frequencies of dustbathing were greater when hens were held at 22 than at 10 degrees C (P < 0.01). In a second experiment, a radiant heat source or a radiant heat + light source, balanced to give the same radiant heat, resulted in more dustbathing behaviour during a 1-h stimulus period than during the same period with no stimulus (P < 0.05). Components of dustbathing were increased more by the heat + light stimulus than by the heat stimulus alone (P < 0.03). In a third experiment, the amount of dustbathing performed by individual hens in cages with dustbaths was increased by the presence of a group of hens dustbathing in an adjoining pen with a dustbath compared with the amount occurring when the hens were absent from the pen.
