Has anyone used any joint supplements? After about 5 min of walking the steer he starts to hold his rear leg and won't put any weight on it. He flex fine at hocks and pasture but it seems to be in his hip. With the high temps we have been leaving the steer in the cooler room 23 hrs a day we take him out at 5 am and try to walk him for about a hour. After walking we rinse and after he gets cool he puts weight on it and walks sound as a cat. Is it just lack of excersise, heat or ?? We keep them seperate so I know he didn't get bump or pushed around and he is on dirt outside and mulch on dirt inside.
