You can't find any more info about it in Iowa, or about Trich? It is hot out here, and all non-virgin bulls have to be tested in MO before being sold now (although, how are they going to enforce that... neighbor sells bull to neighbor???). I can tell you that the two bulls we sold in the State sale in the spring we Trich tested, even though one was a virgin and the other was just 15 months old and had bred one cow in our herd. It only cost $35 to get the semen test done and trich test, so well worth the buyers piece of mind in my opinion.
