Continuing previous analogous investigations on climatic factors limiting the performance of cattle, temperature and humidity values were determined in southern Nigeria and were related to the established physiological compatibility conditions for cattle. A good agreement was found between the values determined in 1984 and 1985. On average (for both years) the outside temperatures surpassed the physiologically-compatible limit of 24 degrees C to the extent of 57.8%. Not more than 1.3% of the total hours were within the optimum temperature range for cattle. The values for the relative humidity were within the optimum cattle range by 27.4% in the two-year average, whereas they were too moist by 35.1%.
继续之前关于限制牛生长性能的气候因素的类似调查，在尼日利亚南部测定了温度和湿度值，并将其与已确定的牛的生理适应条件相关联。1984年和1985年测定的值之间发现了良好的一致性。平均而言（两年的数据），室外温度超过了24摄氏度的生理适应极限，超出幅度达57.8%。在总时长中，不超过1.3%的时间处于牛的最佳温度范围内。两年平均来看，相对湿度值处于牛的最佳范围内的时间占27.4%，而过于潮湿的时间占35.1%。
