The presence of functional rhythmic variations is a well-demonstrated phenomenon at all levels of a physiological organization and especially in the functioning of cell components in tissues and organic systems. The circadian rhythmicity of livestock has received very little attention in chronobiological literature. Taking this little knowledge as a starting-point, the authors studied seven Ragusana breed donkeys in order to observe the circadian periodicity of their body temperature and some of their haematochemical parameters. A periodic statistical model was applied to the average values that were obtained. These results showed circadian rhythms of body temperature, glucose, triglycerides, phospholipids, total lipids, NEFA and total cholesterol.
