| I think you will be happy with Guardian. We started using it three years ago. Had simular experience. Weather and enviroment play a big part, but last year was no picnic fighting the mud. Scours has not been a problem since we started with Guardian. Get two shots in the first year and booster annually. I heard from the Schering rep that they were doing some tests on being able to give the booster up to six months pryor to calving. Nothing in stone as of yet. | |
