A New Technique for Climatological, Nutritional and Energy Metabolism Studies with Ruminants

Abstract

PROJECTS dealing with the relationship between animals and their climatic environments have been growing in frequency for some time past. In particular, climatological chambers have been established wherein domestic animals can be subjected to controlled variations in temperature, humidity, rainfall, wind, etc. Nutritional and energy metabolism studies are also receiving concentrated attention with the building of room-type calorimeters going on at several centres. At this laboratory, however, during the examination of certain physiological processes in sheep, a new technique has been devised which overcomes to a certain degree the need for such costly installations before calorimetric work can proceed.
