Have an old broken mouth cow thats not doin real well. She has a bad eye, and is a bit gaunt, showing signs of lice. Probably wormy too I would guess. Anyway, gonna run the girls through tomorrow and brand calves, etc. Is it okay to give her Ivomec (pour on) for the parasites, and LA200 for any infection she may have resulting from the eye problem? It doesnt seem like it would be a problem but I wanted to make sure I didn't do more harm than good. Will cull her in the fall but need her to raise her calf first and don't want her suffering. Thanks for any input.
