Of all weather-related conditions, heat kills more than lightning, tornadoes, flooding or hurricanes. A heat wave will blanket many sections of the U.S. this weekend affecting humans and animals. Agricultural experts report that during hot weather, cattle drink more and eat less. Accuweather.com reports that an average cow consumes as much as 8.4 gallons of water per day while grazing and this year, daily water consumption is down to 0.6 gallons. In drought-stricken Texas, cattle are not dying from thirst but from consuming too much water. Cattle producers have moved their stock from pastures with dry water tanks to pastures with healthier water supplies. Cattle are gorging themselves then dying from water intoxication. Blazing sunshine is also heating pasture ponds, creating deadly algae blooms.
