Started using Scour Bos 9 since calving at a different location now. When calved at the ranch we didn't use any scour vac.
One of the local vets recomended this versus the Scour Guard for protection. I asked him if it was based on company loyality or resuts. And he said he isn't with any one company and see best results with the Scour Bos.
Last years results. When it did snow , wet some of the calves did scour, however I wouldn't know what would have happened if the cows didn't have any scour vac in them at all. (control).
