I am looking for opinions/advice/info. on Umbarger Show feeds? Pros/Cons?? I know there isn't alot of difference between the bagged show feeds, but I am trying to find some opinions on those who use or have used it. I have been told it is the best bagged feed out there to people don't like it because it freezes and becomes like a concrete block when it gets cold or it molds to easy and you can't use it. Just curious to see other opinions. How soon do you usually switch from Cattle Blaster to Barley Based if your main show goal is August?
