That s their first line of defense. In all actuality, the environment should be the first variable that producers consider. The ideal calving environment would be a fairly steep hillside pasture with a windbreak, accompanied by warm, dry weather. This scenario, however, is not usually the case for calves born during an Iowa spring. Allow heifers to calve separately from cows.
Heifers are much more likely to have calves with scours.
Producers should clean and disinfect all calving areas to the best of their ability. Keep calves dry and warm. Bed them deeply with cornstalks. Hartwig also suggests portable calving sheds or temporarily partitioning areas of a barn with a creep bar that can be deeply bedded. Calves will use these areas and they are easier to keep dry when access by the cows is prohibited by the creep bar.
