Was chating with vet the other day. He has seen shorter gestations lengths and lighter spring born calves then usual. He's wondering if it maybe has to do with the really mild winter. What he is seeing this spring is what usually happens with fall calving. He also said he has noticed that a lot of ET calves are coming earlier than expected. Typically he said that ET calves gestation is a little on the longer side but this year seem to be shorter. All anecdotal but still something to think about.
