My grain formula which my vet in the 80s helped me
with had about 50% corn and 50% oats along with some other goodies. Protein
about 11%. My horses for over 20 years have done great on this feed
grain. Healthy, maintain weight really well, never tied up, plenty of
energy at rides, placed in the top 10 - 5 many times, and one mare even
won a 100 in 9+ hrs and won BC. My thoughts? If it works, don't try
to fix it!! It works for my guys, but then I don't have to feed much grain
and the horses have a great big pasture (7 - 20 acres). Bottom line,
figure out what will work for one's horse in whatever situation that horse
lives. What works for one won't necessarily work for another.
