A total of 60 broiler-type birds three weeks of age were divided into two groups and acclimated for three weeks at either 8 degrees or 30 degrees C. Twenty birds from each environment were fed conventional broiler ration and ten birds were fed a ration with no sodium chloride added. The 22Na retention was significantly higher in birds acclimated at 30 degrees C., than in those held at the 8 degrees C. environment. Birds receiving a diet with normal sodium intake had a significantly lower 22Na retention than those receiving a sodium deficient diet. There was no significant differences in 22Na retention between the birds from the two environmental temperatures receiving low sodium intake. It was concluded that the sodium intake had a greater effect on sodium retention than the effect of the environmental temperature.
将60只三周龄的肉仔鸡分为两组，分别在8摄氏度或30摄氏度环境下适应三周。来自每个环境的20只鸡饲喂常规肉仔鸡日粮，10只鸡饲喂不添加氯化钠的日粮。在30摄氏度环境下适应的鸡，其22Na保留率显著高于在8摄氏度环境下饲养的鸡。摄入正常钠饮食的鸡，其22Na保留率显著低于摄入缺钠饮食的鸡。低钠摄入的两组环境温度下的鸡，其22Na保留率无显著差异。得出的结论是，钠摄入量对钠保留的影响比环境温度的影响更大。
