Extension HUNTINGDON (Huntingdon Co.) —The warm days and nights have given the com the boost it needed. There was some frost around the area in the first part of June. Now that the warmer weath er appears to be with us let’s open the bams so the animals are comfortable. Robert Graves, Penn State Extension ag engineer, has some of his own thoughts on the basics of cow environment High ambient temperature and humidity can have profound effects on milk yield, reproductive performance, growth and health. The basic approach to hot weather cow management includes: Keep the cows out of the hot midday sun, maximize air movement around the cows (2 to 5 mph at the cow is recommended), provide adequate air exchange to remove foul air from bams, and provide plenty of fresh cool drink ing water (extra tubs may be needed during the' summer). The word SAW may help with remembering (he important points about hot weather cow care as relates to buildings. S • shade is important to protect animals from intense summer sun shine. Natural shade, a shade structure or a well ventilated bam are all suitable. A • air movement and air exchange are necessary to help animals remove body heat. At temperatures over 80 degrees, air moving at 2 to 5 mph will increase cow comfort and help maintain production. Removable sidewalls Not Cows Corn, and open ridges are necessary in naturally ventilated bams. Adequ ate exhaust fans and air inlets arc essential in mechanically venti lated bams. Extra circulation Tans blowing air across cows may be beneficial in cither situation. So called tunnel ventilation systems can be used effectively in the stall bams. This involves placing large ventilation fans (total 60,000 cfm of more) in one end wall of the stable. Windows, doors, and large inlets arc opened on the other end of the stable. W - water, and plenty of it, is needed to make milk. In hot weather, the cow will utilize water first to help cool herself through respiration moisture and sweating. Any water left over will go for milk production. Add extra water ing locations, shade the outside watcrcrs, and be sure water supply is adequate. Two areas of particular concern during hot weather include hold ing areas and feeding areas where cows arc crowded close together. Farmers arc encouraged to take steps to provide fresh, palatable feed and fresh water in a comfort able environment. If the bam or shade tree is more attractive than the feed bunk or water trough, it is likely that feed consumption will decline. ■ . Management changes that may be considered include; feeding lime and frequency, manure scraping limes, use of outside pad docks at night or early mdming, and bringing cows into well ventilated bams during the heat of the day.
