SUMMARY Within 22 days after 30 pregnant cows inadvertently received silage ad libitum , one had a mycotic abortion and 2 gave birth to calves with mycotic encephalitis. The latter 2 cows both developed severe mycotic pneumonia within 3 days of parturition. Variable diameter, non‐septate, irregularly branching fungal hyphae were found in all lesions. Mortierella wolfii was cultured from the cow's lung, both calf brains and the silage, which was the probable source of infection.
