Notes
  • Homoeothermic animals maintain body temperature within their normal range while exposed to high ambient temperatures by a variety of behavioural and physiological responses designed to reduce heat absorption and/or increase heat loss.
  • In waterfowl, a major part of thermoregulation in hot conditions involves behavioural responses such as moving into shade and swimming.
  • Hyperthermia is more likely to be seen in waterfowl which lack access to water, shade or both.
  • Downy waterfowl being hand-reared in small runs are recognized as being particularly prone to overheating in sunny conditions.
  • Waterfowl being warmed as a treatment for hypothermia may also become overheated if not properly monitored.
  • Maintaining downies in warm brooder boxes throughout the rearing period may increase the risk of the development of Angel wing, as less energy is required for keeping warm so more may be used for growth, which may be too rapid.
  • High ambient temperature is well recognized as a risk factor for the development of capture myopathy
  • High ambient temperature is also recognized as a general stressor which may increase susceptibility to disease.
