[Hyperplasia of the ruminal villi in three wild roe deer]

In autumn 1994 a hyperplasia of ruminal villi in three roe deer out of one hunting ground was diagnosed. The ruminal villi were three to five times longer than normal and partially stuck together. The case history and a comparison of the pathomorphological and histological findings with similar symptoms in domestic ruminants lead to a discussion on feeding as the cause of the disease.
