General Discussion

Not nearly as bad as in chickens, but still having an effect.

Common clinical signs in affected cows include low appetite, reduced milk production, and abnormal appearance of milk (thickened, discolored). Lactating cows have been most highly affected, and signs of illness have been reported in less than 10% of cows within a herd.
