Pre-partum cows and heifers were placed in another barn (stall) approximately 600 meters away and were not affected. Furthermore, the cows in these batches did not develop diarrhea, which may have been due to their lower production exploration. The lactating cows were both pregnant and in high milk production, while the other batches of cows were either not pregnant or both not pregnant and not producing milk. Neonatal calf diarrhea was not verified in the calves batch either.
