    It boils down to genetics, and unfortunately at this time the genetic reason for sunfading is not known.

    My bay didn't have a problem with 'sun bleaching' until we came to the US - we don't get as much really bright sun in the UK
    None of my others are affected though
    There a link between copper deficiency and sun bleaching?

    Could this affect only certain horses in a group that all graze together?

    So jaydee, any recommendations on a supplement that might fill in some of the potential gaps in minerals? I already ordered SmartDark and Handsome (I thought I ordered Black as Knight because I searched for it and this product was the only one that came up, seems to be their version of it), which says it contains these:

    I'd looked at those products after I found the link with copper deficiency but was concerned that I was already feeding those vitamins and minerals in with the complete feed I use - she gets a mix of Sentinel Senior, Triple Crown safe starch forage and TC low starch pellets so I was worried about overloading her with something that might cause problems (plus spending money on a whole load of ingredients I didn't need).
    If it was my land that was copper deficient then I'd expect to see the same bleaching in the other horses but some humans can have deficiencies even on well balanced diets so maybe horses are the same
    Too much iron in the diet can cause copper and zinc imbalance - also related to ground you are on
    That would also cause poor hooves which she doesn't have
    I will maybe get a soil analysis done
    I started looking for a straight copper supplement but not getting any results that I felt comfortable with in terms of ordering on line

    I just sent a note to my trainer/barn manager asking how much of each feed Sandie eats per day, so that I can figure out exactly how much of each mineral she's already getting.

    She also gets 5-6 flakes of good quality Timothy/Orchard mix hay per day and goes out on grass pasture for 1-2 hours per day as well.

    So if she gets 4 1/2 lbs of this feed per day (if I am doing the conversion correctly!) she gets around 100 mg of copper per day and 325 mg of zinc per day? That seems awful high, when the websites I found recommended that a 1,300 lb horse (which she is NOT, she's more like 800-900, she is only 14.2hh) should get 60-90 mg of copper per day and only 40 mg/kg of zinc.

    Then in addition, I read that higher zinc:copper ratios can cause problems...and this feed has a 160mg:50mg zinc:copper ratio, so that doesn't sound good? But why would they make a feed like that if it wasn't a good idea? Hmm, this opens up a whole new book of nutritional research for me!

    I don't have time to go through the maths on that - whats the recommended daily feeding amount for that product?
    It always worries me that its so easy to over feed these mineral and vitamins - a lot wont hurt as they just get excreted but some can be harmful or upset the balance which could be whats happening.
    You should probably go through it all and make a table of exactly how much is coming from the feed in terms of minerals and vitamins because some will also come naturally from the hay and grass.
