We had this guy come and preg check our cows last fall. He trains others how to do it. I was told he was good, really accurate. I of course was sceptical. Out of 15 cows he was within a couple days on all but 2. On our only heifer, he gave me a may 21 due date. She calved at 5 am yesterday morning. I am now pretty impressed. He can tell by the size of the skull or the size of the umbilical cord. We are done calving now I can get some sleep. :)
