摘要：

This paper describes the effects of ambient temperatures on whole blood viscosity and plasma protein concentration in broiler chickens. Whole blood viscosity and haematocrit, compared at 7 and 20 degrees C, decreased significantly at or above 25 degrees C of ambient temperature. However, no marked difference were found between 7 and 20 degrees C or between the temperatures of 25, 30 and 35 degrees C. The heat-induced decrease of whole blood viscosity was found after exposure for 1 h. These results suggest that the heat-induced decrease in blood viscosity is only a level change, which occurs between thermoneutral and high ambient temperature. (C) 1999 Elsevier Science Ltd.
