Great post! More owners need to take the time to read labels and know what they are feeding their animals. If you don't mind, I am going to print and share this with a horse acquaintance...we have had friendly disagreements on how and what to feed. Primary dispute was on feeding breeding mares/foals. They were insistent on supplementing them and put them on calf manna and way overfed it - they took advice from someone who raises cattle. They got the big baby they wanted, but as it was fed like a feeder steer that needed to grow fast their filly now has a serious case of epiphysitis and may never be sound :( I dearly wish now that they would have listened or at least taken advice from someone who owned horses, in 40 yrs of raising babies we have never had any epiphysitis issues and after seeing one with that problem I am so so so thankful!

more horse owners need to learn how to do conversions so they know that the % on the tag doesn't mean alot too:)

I have been called the NSC Nazi more then once ... I hate traditional feed methods of loading our horses up on grains and junk food :)

There's another chart that says what different feeds have in them. I'll have to share it with you when I get home.
