You said WE - not they. Tablets can be crushed and given orally. I'd rather take the time then add more risk to the situation.
I said we, because depending the day, certain people fed all the horses and made the feed up. And I tried to tell the people that orally, would be much better that they shouldnt be eating, but the then told me that they can't even worm their horse. So I just did what I was told.
The point I was making, is that every similar case I've dealt with/been around, they used bute rather than banamine.
