  • In the present work, we have studied daily rhythmicity of body temperature (Tb) in Arabian camels challenged with daily heat, combined or not with dehydration. We confirm that Arabian camels use heterothermy to reduce heat gain coupled with evaporative heat loss during the day. Here, we also demonstrate that this mechanism is more complex than previously reported, because it is characterized by a daily alternation (probably of circadian origin) of two periods of poikilothermy and homeothermy. We also show that dehydration induced a decrease in food intake plays a role in this process. Together, these findings highlight that adaptive heterothermy in the Arabian camel varies across the diurnal light–dark cycle and is modulated by timing of daily heat and degrees of water restriction and associated reduction of food intake. The changed phase relationship between the light–dark cycle and the Tb rhythm observed during the dehydration process points to a possible mechanism of internal desynchronization during the process of adaptation to desert environment. During these experimental conditions mimicking the desert environment, it will be possible in the future to determine if induced high‐amplitude ambient temperature (Ta) rhythms are able to compete with the zeitgeber effect of the light–dark cycle. more »

  • Coccidiosis is a parasitic infection of alpacas that can also be found in a wide variety of other animals such as cows, poultry, and dogs. The cause of the disease is the infestation of the intestines of the alpaca by a parasitic protozoan. Symptoms of coccidiosis in alpaca include dehydration and loss appetite. There can also be diarrhoea, possibly with blood in it. Medication is available for treatment of coccidiosis in alpaca. But good management techniques should also be introduced to prevent outbreaks. more »
