Is the Iron in my horse's hay test unavailable for digestion?
Question: My hay test shows very high levels of iron. Equi-Analytical rep states "We got the results of the re-test today and the iron result has confirmed the original. It is likely that the sub sample we have has been contaminated by soil or dust. In this case, the iron we are picking up on is likely unavailable to the horse during digestion". Is this true? That it may be unavailable for digestion?
Dr. Kellon: No. It's not true. Research has shown that foals raised in stalls without the ability to eat dirt become anemic. So do baby pigs raised on concrete. The piglet problem has been well known for many years. One of the solutions is to put a pan of dirt in with the piglets.
