Abstract
It has been established that providing comparable and standard environmental conditions to house experimental rats is of high importance. However, there is growing evidence that rats prefer higher temperatures owing to their thermoneutral zone that lies between 28-34°C. This experiment validates the stress levels of Wistar rats of both sexes housed in conventional conditions about 24-31°C and a relative humidity of 70-92% in a tropical animal facility when compared to rats housed in controlled temperatures of 20-24°C with humidity maintained between 30-70%. Adequate air-changes to maintain ammonia-free environment was provided with a power-exhaust system in a conventional setup and with the individually ventilated caging system in the environmentally controlled group. To assess stress, faecal corticosteroid metabolite assay was done in naïve animals and in a set of animals that underwent retro-orbital bleeding under general anaesthesi...
