We banded several bulls about 8 days ago, they are weighing about 700. One bull today we noticed has some swelling above the band, looks like fluid build up. Not huge, but noticeable if you look. He is eating fine and seems otherwise healthy, but you can tell it is uncomfortable to him. Do you think he needs treated? If so, with what? He was given a tetanus shot at banding and he is the only one of 15 that has this problem.
