Abstract
The changes in intestinal digestion of the Somali donkey due to both a simulated desert environment (exposure for 12 h at 22°C (dry bulb) and 18°C (wet bulb), followed by a further 12 h period of exposure to an ambient temperature of 40°C (dry bulb) and 24°C (wet bulb), referred to here as 22-40°C condition, and to a stress condition consisting of a water restriction up to a 15 % level of dehydration with and without heat load, were investigated. Dehydration at both environmental temperatures (22°C and 22-40°C), separately, depressed food intake and increased apparent digestibility of dry matter, but an intermittent heat load as found in the desert environment per se had no effect on either parameter.
