My son's steer has swollen hocks. The left is worse than the right, and the swelling is mostly on the front of the hock and the ball of the hock. He moves normally and is still playful and energetic. Any ideas on what can cause this. I should probably tell you that he weighed 1175 on Saturday, and his toes are long. He's getting his feet done sometime this week. I don't know enough about cattle to know how to fix it. He does not show pain and there is no heat. :-\
