Show New Unit Improves Ventilation of Barn Dairymen Find Device Particularly Effective Many of a cow's troubles can be traced to heat and humidity. A cow, unlike a human being, can perspire only through the mouth. So when the temperature and humidity hu-midity inside a barn get high, the animal becomes uncomfortable and stubborn, particularly at milking time. According to the department of agriculture, an average cow gives off almost a pint of water every hour through breathing. In addition addi-tion to the high humidity caused by this breathing, a cow has an extremely high body temperature. During the winter months, when the cows are in the barn most of the time, this combination results in generation of an enormous amount of water vapor and heat. When the warm, moisture-laden air comes in contact with the cold walls, condensation occurs and frost is formed. The net result to farmers is rotting rot-ting beams, joist and siding; a loss of hay because of mold created by moisture and frost: milk contamination, contami-nation, disease, particularly among the young stock and reduction of milk production because of discomfort discom-fort to cows. A simple solution to all of these costly problems is an automatic cooling unit, which is proving popular pop-ular with dairy farmers. These automatic ventilation units, easily installed, reduce condensa- S,li.l..Jt..-.'.Jt.tto,np m,'mt -- frif Hint -r'nl Picture on Vernon Julins farm at Freeport, 111., shows installation installa-tion of automatic cooling unit in dairy barn. tlon to a negligible degree less than 2 per cent. This action, in turn, decreases barn deterioration, hay mold, milk contamination and disease. It also provides much more comfort for the cows and increases in-creases milk production. In addition, addi-tion, working conditions for the operator are much more pleasant. The cooling units are equipped with an automatic "airswitch" thermostat. |
