One of my steers this year seems to get stiff after shows once returning home. He also gets stiff if he lays down for long times at the shows but he is able to walk it out. What is causing the stiffness after the show? Also he seems to be very lethargic and tired at shows and even the day after...overall he is sound just gets stiff. Is there anything I can give him to boost his energy he tends to even lay down in the ring while showing.
