I have high iron and high selenium in my area/soil.

From what I read Iron can cancel out some things.

I have also seen and read that horses are not getting enough Amino Acids and protein.

On your feed program I dont see a listing of Iron, copper, and so forth.

Does that mean it doesnt have it? if not should a Amino Acid be added if you have high Iron?

Thanks

and I am open to anyone else's insight. 

I have no answers just wanted to thank you for asking these questions. I would like to learn more on this myself. 

Thanks for the question. Daily Iron and copper contribution from Renew Gold is not high, though both are present, as is selenium. We do not add any of these, and that present is naturally occurring. Balancing selenium in areas that are deficient can't be done in feeds for the reason that you state here. A few areas have selenium toxicity. None of these issues are negatively effected when feeding a RG diet. As to protein levels, this depends on roughage quality. The protein level of Renew Gold is 15% with all essential amino acids present. That said, total protein needs should be met with a combination of Renew Gold and good hay or pasture. If not, the best course of action is to get better hay rather than a ration balancer. Ration balances are only appropriate if better roughage is just not available. I just had complete blood work done on one of our mature cutting horses. The result was as expected, perfect. That horse is hard working and a road warrior. Total diet is mixed hay with some pasture,  1 1/2 pounds of Renew Gold and a Redmond Rock salt rock in his stall. Since the hay quality is high, no other protein or amino acid support is needed. 

Without your forage tested. 

I think most people think their forage is a lot better than it really is. 

I agree that many horse owners do not know the actual quality of the hay that they are feeding. If you are buying in large amounts it can be a benefit to have the hay tested. In some areas the better hay brokers test truck load lots and can provide someone who buys smaller amounts of those lots with analysis information. If you just buy a few bales at a time from your feed store or hay broker there is little reason to test it yourself, as that hay will be fed out and you will be feeding hay from a different lot by the time the test results come back. If you grow your own, there is no reason not to test it and know what you are producing.  Your hay should be the foundation of your horses feeding program. It can be difficult to design the most effective diet possible without knowing what that foundation is actually capable of contributing to the overall diet. There are a number of other factors like teeth condition, overall diet make up and resulting hind gut effeciency that contribute to how effective the hay you are feeding can be. The best horse hay in the world has little value if the horse has too many digestive road blocks that keep the horse from properly digesting it.

This!!! I board and they always go for the green soft alfalfa, because they think it's so rich. And then the horses just kind of pick at it and some lose weight. Then they'll get a load of some other stuff thats a little more stemy and slightly brown and the horses thrive. And they're always so confused as to why they do better on the lower quality hay. I try to explain to them that they don't know which is better without testing it, but they just assume color is best to determine quality. Drives me nuts. So I'll tell them to feel free to feed the stemy brown stuff to mine and save the dark green fluffy stuff for theirs. I figure if my horses stay a nice weight on that and lose weight on the other, its working better for them. And they don't get grain or ration balancer so hay is most important. But I wish more people would test their hay and not just assume quality based on color. We did a testing experiment in school and sometimes the sketchy hay that you almost want to feed to the cows was better than the nice green stuff you want to fill your barn with. When I have my own place I will test the hay that I purchase for sure

I did bloodwork for selenium and Thank goodness I switched to Renew Gold Senior! My vet said he was so close to Toxic level! and not to feed anything with selenium and supplements with selenium.  Also Vit. e was high which was good!

We are able to do our own hay now and I will be testing it as soon as possible!

Since I have switched some stuff I will be doing the blood work again and see if it comes down! 

By the way where I live we have high selenium and Iron in our ground. 

You might also consider replacing some of your local roughage with a source from outside of your region. Perhaps some hay cubes. This would reduce overall selenium in the diet. 

I have battled with Selenium for several years now. Droughts make it worse. Two horses were toxic and lost their tails and their hoof walls sloughed, two years and their both finally back to normal. 

Feed high protein diet, equilix tubs(without molasses) have been a life saver, I have them out at all times. I know it has Selenium in it but because of the protein, which binds to the selenium, it hasn't made my horses selenium levels go up. I also use Sulfer salt blocks and I was using Equilife Biotin Plus for awhile when it first started and it helped.  

The Selenium is in the weeds primarily and the more moisture that is in the ground the lower the levels you will find. I usually don't turn anything out on dry lands unless its fall and winter. We irrigate pastures all summer so they are turned out when water isn't going but I make sure that I still have the Sulfer salt blocks out and the Equitubs out. We haven't noticed any effects on the cattle surprisingly and only two horses had toxic levels.. kind of weird. 

I currently feed Renew Gold but would like to do the blood test as my mare has had some changes since starting it.

Win, was your vet the one that did bloodwork or is there an analysis lab that you sent it off to?

We had the horse at the vet for a stone bruise and I asked for a blood work up while we were there.
