I was wondering what brand of vaccines y'all use. Are you loyal to Pfisher (sp) or any one company? It seems, looking in my fridge, I use a little of everything, and have alot of leftovers that never get used and need to go. Calves get vision 7, and I was wondering can I shoot them with preg guard 9, or do I need to use that just for te cows before breeding. Can scour guard be boostered with scour Boss? What do you use....start to finish?
