Start with less than a full dose. Feed before you give hay, when your horse is hungry. Mix it with your horse's favorite taste-tempting ingredients. From the Files, the Picky Easters Checklist. https://ecir.groups.io/g/main/files/9b%20Pulling%20it%20Together/Picky%20Eaters%20Checklist.pdf
These are the toolkit that I keep on hand to introduce new things:
-a handful of Stabul1
-a small measure of FORCO pellets or powder sprinkled over the top
-a sprinkle of Uckele CocoSoya granular over the top
-a handful of Cavalor Fiber Force
-a handful of ODTBC
-a handful of RSR BP
-a squirt of CocoSoya oil to make tasty powder stick to pellets or BP
I never use all of them at once. You don't want to end up with a an exotic mix of 5 or 6 ingredients.

I've also used fenugreek leaves. They smell divine. https://www.amazon.com/Rani-Fenugreek-Natural-Kasoori-Ingredients/dp/B018PUTG24 

 I do use a wide feed pan to help dissipate new odors.
