Extreme to exceptional drought conditions across Oklahoma dried up much of the hay and forage crops needed to keep cattle herds healthy through the winter.
Not only are food sources scarce, experts say, the forage available could be toxic to livestock. The combination of drought and unseasonably hot weather boosts nitrate levels in sorghum, corn and other forage crops, and can be deadly.
