Reduce Stress C occidiosis shows a common pattern of outbreak. Constant, low-level exposure builds immunity in old cows. New calves with a little or no immunity enter that environment, get infected, get stressed, and break with scours. T he most common stressor that causes an outbreak is moving heifers from individual to group housing. Weaning and any significant ration change also cause breaks.
M ake sure calves get a good dose of quality colostrum immediately after birth.
Re-evaluate your vaccination program, and deworm calves. Keeping the immune system strong and eliminating concurrent worm burdens allows calves to better withstand coccidiosis. Medicate D airies often adapt a strategy of continual medication against coccidiosis as a prevention. However, with an understanding of the disease's cycle and knowledge of your infection level, you can adopt a strategic prevention that targets medication to the weak links. C ORID's flexible administration is also important during an outbreak because it can be given as a drench, in drinking water as well as in the feed.
