I was talking to my farrier about pelleted feed and mineral/salt blocks and he insisted that both were bad for horses. The pelleted feed he insisted were bad for horses because the pellets are baked which causes the natural enzymes to die which causes the pellets to be harder to digest. Which could cause your horse to develop a stomach ulcer. He also said that the mineral/salt blocks were bad because the minerals are not natural which makes them not easily circulated throughout the horses body.
Now I am very skeptical about both of his claims on these two topics. I am just wondering what other people who are knowledgeable about horses think about what my farrier claims.
