TAILIEUCHUNG - Conversion to Organic Milk Production: the change process and farmers' information needs

Many animals respond to a hot environment by resorting to an increased respiration rate and in some cases to open-mouth panting. Respiration rates in the camel increase very little with increase in ambient heat load and the respiratory route, probably, is a very minor source of water loss. In addition, camels are able to exhale unsaturated air under some conditions. The combination of cooling and desaturation can result in saving 60% of the water that would be present in fully saturated air exhaled at body temperature. A lower rate of breathing at night also increases the tidal volume. | Susanne Padel Conversion to Organic Milk Production the change process and farmers information needs PhD-Thesis December 2001 Institute of Rural Studies University of Wales Aberystwyth DECLARATION This work has not previously been accepted in substance for any degree and is not being concurrently submitted in candidature for any degree.
