Guidelines for specification of animals and husbandry methods when reporting the results of animal experiments.

Any report on the results of animal studies must include sufficient information on the animals used and their conditions of husbandry to enable the reader to understand how the investigation was performed. Only then can he properly interpret the findings. These guide-lines provide a catalogue of the minimum information which should be included in such…

Effects of room temperature on reproduction, body and organ weights, food and water intake, and hematology in rats.

Two generations of rats were raised at animal room temperature ranging from 12 to 32 degrees C at steps of 2 degrees C. The body weight of rats born in 22 degrees C environment and exposed to each temperature did not significantly differ within the range of 16-28 degrees C. The delivery rate, litter size,…
