The effects of environmental temperature on the blood potassium concentration of chickens of different ages were studied. The mean environmental temperatures used were 8 degrees, 19 degrees and 30 degrees C. There were no statistically significant differences in blood potassium concentration between age groups within a given temperature. Birds acclimated to an environmental temperature of 30 degrees C., had a lower mean blood potassium concentration than birds acclimated to an environmental temperature of 8 degrees C. There was no significant difference between the birds at 19 degrees C. and the other groups. Birds transferred from the 8 degrees to the 30 degrees C. environmental temperature showed a significant decrease in whole blood potassium concentrations as early as six hr. following transfer. In birds transferred from the 30 degrees to the 8 degrees C. environmental temperature, the blood potassium concentrations before and after transfer did not differ significantly. The results of this study indicate that blood potassium concentrations change with acclimation by the domestic fowl.
研究了环境温度对不同日龄鸡血钾浓度的影响。所采用的平均环境温度分别为8摄氏度、19摄氏度和30摄氏度。在给定温度下,各年龄组之间的血钾浓度无统计学显著差异。适应30摄氏度环境温度的鸡,其平均血钾浓度低于适应8摄氏度环境温度的鸡。处于19摄氏度环境温度下的鸡与其他组之间无显著差异。从8摄氏度环境温度转移到30摄氏度环境温度的鸡,在转移后6小时,全血钾浓度就显著下降。从30摄氏度环境温度转移到8摄氏度环境温度的鸡,转移前后的血钾浓度无显著差异。本研究结果表明,家鸡血钾浓度随适应过程而变化。
