Thermal interaction between animal and microclimate: a comprehensive model

摘要: An equation based on heat transfer theory is developed to predict the rate of loss from a homeothermic vertebrate environment, specified by air temperature, humidity, windspeed and radiation receipt. The analysis incorporates animal's thermoregulatory responses—sweating ability, vasomotor action, regulation body-core metabolic respiratory rate. water vapour cattle used as an illustration, particular attention given their balance in hot environments. predicted rates indoors at various temperatures humidities are consistent with experiments. Outdoors, intercepted solar can reduce substantially through body tissue when temperature low. In contrast, high dissipation may not be sensitive load, although is. Increased movement aggravate strain low temperatures, but mitigate environment.
