Calling all vitamin and mineral specialists

I am currently in the process of doing a spreadsheet on the daily supplements I feed my horses. I am seeing if I am doubling up/overdoing on any vitamins or minerals and wasting my money.

Does anybody know where I can find on the internet maybe even a link that has all the recommended daily requirements for horses on minerals and vitamins etc. I can not find any on the net that are straight forward, I preferably need them in grams, mg, Iu etc.

Hoping someone can help. Cheers in advance.

First of all, you need to know exactly what your feeding. Minerals and Vitamins need to complement a feeding program. So, if you are feeding manufactured feeds, you need to know exactly what is in them already. Many are fortified with Vitamin PreMixes and adding more Vitamins only messes a horse up.

Then, you need to know the mineral content of your forage. For example, if you are feeding alfalfa, you are getting plenty of Calcium.

On the other hand, if you are feeding grass, grass hay and/or any grain products, you are feeding a lot of Phosphorus and are probably not getting enough Calcium.

You cannot get any mineral OUT of your feed, so you have to supplement what is needed by adding other minerals to your feed. You cannot get the excess Phosphorus (P) out of grass or grain, so you need to add enough Calcium (Ca) so that the horse is getting twice as much Ca as P.
