Anyone use first defense for baby calves? Work good? We currently give a oral Ecoli tube at birth and vaccinate all cows with scourguard for roto/carona . This works good but trying to cut down on so many vaccinations, would be nice to give just one pill at birth and also wouldn`t have to do all bull calves which would reduce cost some. Thanks.
