Neonatal calf diarrhea, also known as calf scours, is often caused by viruses, bacteria, and parasites. Scours can be deadly for young calves as they experience a loss of water and electrolytes through the gut and quickly dehydrate.
Where did the calf get exposed? If a calf becomes sick in the first five days, infection most likely happened in the maternity pen. If calves become sick once they’re more than seven days old, they were likely exposed to infection in their own environment, the calf pen.
