The zinc is high in the diet. You apparently didn’t pay attention to my past posts, including the present one. Another poster suggested a half dose. You suggested multiple times this supplement, and I took you up on it. You were wrong.

Fly sheets help with fading 
It doesn’t stop it entirely but it does offer some UV protection. I think there are also SPF sprays that can be used… I just hate coating them in “stuff” all the time because often you have to wash it off later.
I don’t think anyone on this thread has any formal education in nutrition, much less equine nutrition, and they are just cobbling together things they read. I tried the same supps for a scratches prone horse and it made no difference.
I suggested a half dose of copper and zinc. You still haven’t done that. Shrug.

Thankfully we are “cobbling together” all this stuff we absolutely DID read - from the experts. Whew, good to know we aren’t just making this stuff up! Would you prefer that any time anyone with out a formal degree in nutrition, provide scientific cites for any information offered up?

“Depigmentation and impaired keratinization of the coat indicate low copper or zinc status. Typically, when copper is low, chestnut coats will appear to have a yellow tone to them and black coats will have a rust appearance. You might especially notice this color shift in a horse’s mane. Coats appear to fade over time due to ultraviolet light causing damage to the pigment leading to color change. If pigment levels are high, coats have greater resistance to damage.”
And this entire site is FULL of people telling what has worked for them. This includes you.

There is a difference between telling people what brand feed you use and how if affects your personal horses, and diagnosing malnutrition and telling people to add a chemical element to the diet.

Of for Pete’s sake, nobody diagnosed anything :rolleyes:
People have regularly and continually said “excessive bleaching is often a sign of insufficient copper and zinc” and “when this happened, I added copper and zinc, and not only did the chronic skin crud go away, the coat stopped bleaching as much”.
You yourself just told someone the best thing for an underweight 3yo OTTB is TC Sr, fed as directed. You never asked about teeth health, deworming, or anything else that might make another suggestion more appropriate. So, there’s that…

I do.
I have formal equine nutrition education.
Along with chemistry.
Not that it matters, because as JB said, it’s really not difficult to search the web for reliable, factual, scientific sources of information. Also, it’s pretty reasonable to rely on actual experience with recommended supplements/feeds/etc. Just like we classify Methanol as highly toxic to humans - though rat studies show results as non-toxic, human experience in industry use shows otherwise. There is no substitute for experience, not even a college degree, and you don’t need formal education to read articles and study results.

Another one to tuck away! I either didn’t know, or forgot, but won’t forget now!

I agree and don’t agree. You have to understand logic, facts, basic chemistry and biology, and basic statistics to understand how to read, interpret and put into context study results. Some very experienced people don’t understand why something works or why two things are related because they don’t understand how chemicals or elements interact with cells in a living system and can’t logically connect cause and effect. Some can. Similar to horse training - you don’t need a degree to be a great trainer. Some very experienced people are great trainers (IMO, they understand logic - cause and effect), some very experienced people are not good trainers (they don’t understand logic, or cause and effect). The range appears on COTH.
I will argue that your education helps you to discern websites with “reliable, factual, scientific sources of information” .
I agree to a degree with Palm Beach. I sometimes find myself arguing with some people who don’t know my horse or his situation at all but they think they do with the limited information I post. They don’t ask questions but instead tell me what I should do. I was told that my horse’s skin issues was due to copper deficiency by someone on this thread despite the fact that my area of the state had record rainfall in 2018 and is on track for the same in 2019. My vet disagrees with this person’s advice. I very much appreciate advice and experience, but dislike personal “pet arguments” that some experienced people stick to without logical explanation of why they are sticking to it or willingness to adjust in the face of facts. I trust my vet - we talk about horse health. I have a PhD in physiology, I understand how animal bodies work.
