In continuation of previous analogous studies on climatic factors influencing the performance of cattle in Northern Egypt (climate types III4a/IV: etesian climate of the Mediterranean type) the present investigation deals with the temperature and humidity for Southern Egypt (climate type III1; arid, subtropical desert climate) and classifies them according to the physiological tolerability ranges set up for cattle. In Northern Egypt (Maryut) 23.8% of the temperatures were beyond the optimum and physiologically still tolerable range (0 to 24 degrees C) and were thus in the intolerable range; 45.8% were within the optimum tolerability range. In Southern Egypt (El Menia) 46.7% were within the intolerable range and only 25.7% in the optimum range (5 to 18 degrees C). The relative humidity values had 21.9% within the optimum range and 63.9% in the intolerable range in the North; in the South 22.9% were within the optimum and 55.5% in the intolerable range.
作为之前关于影响埃及北部牛只生产性能的气候因素（气候类型III4a/IV：地中海型的夏季干旱气候）类似研究的延续，本调查针对埃及南部（气候类型III1；干旱的亚热带沙漠气候）的温度和湿度进行了研究，并根据为牛只设定的生理耐受范围对其进行了分类。在埃及北部（玛丽尤特），23.8%的温度超出了最佳且生理上仍可耐受的范围（0至24摄氏度），因此处于不可耐受范围内；45.8%处于最佳耐受范围内。在埃及南部（明亚），46.7%处于不可耐受范围内，只有25.7%处于最佳范围（5至18摄氏度）。北部相对湿度值有21.9%处于最佳范围内，63.9%处于不可耐受范围内；南部有22.9%处于最佳范围内，55.5%处于不可耐受范围内。
