[Studies of climatic factors influencing the performance of cattle in the Syrian Arab Republic. 3. Assessment of the factors effective in 1969/70--comparison with those of 1968/69].
Continuing previous investigations (1968/69), the values of temperature and humidity (inside and outside the cowsheds) were determined for the period October 1969 to September 1970. They were related to the physiological compatibility ranges established for dairy cattle and discussed in connection with a cowshed scheme in the Animal Experimental Station at Deir el Hajar in the Syrian Arab Republic. The values obtained in the two years of investigation largely agreed. The means of the temperature in both years was 27.7% inside and 30.5% outside the cowsheds above the physiologically compatible range of 0 to 24 degrees C for the whole period. Only in 47.6% and 46.7%, respectively, of the overall hours the temperature inside and outside the cowsheds was within the optimum compatibility range for dairy cattle. 43.5% of the relative humidity outside the cowshed was in the too dry and 21.7% was in the too moist compatibility range.
