Our pig is trying to add weight for our county fair and our breeder told us to pick up some Rooster Booster liquid B12 from our local Feed Supply. I picked it up and now I don't know how to administer it or how much to give! I've called and text him but he hasn't gotten back to me and we are under the gun where every day counts!! Has anyone give this type of B12??? How do I give it and how much and how often do we give it?? We need to work fast which is why I can't wait for his reply! THANK YOU!!!
