Is it possible for Trich to affect my herd?

Trich is the slang name for Trichomoniasis infection. This is a venereal disease of cattle that is spread during breeding. If your herd is free of this disease, the only was it can affect you is by bringing in an infected animal. This is why you should only purchase virgin bulls or cows and heifers that are confirmed at least 120 days pregnant, or with calves at side. The South Dakota Animal Industry board has a very good pamphlet on this subject on its website, sd.aib.org
