Giving medicine...need help!!

I am giving my horse a supplement called " Remission" to help build his hooves back up from where he foundered on grass. He really does not like it. I have mixed it in with a cup of pellet feed and wet it some to help it stick to the pellet. no luck....Then I tried mixing it in applesauce and putting it in his feed. Still he eats around the applesauce and leaves the supplement. Any suggestions?? Normally this horse eats anything but I think he can smell this stuff and does not like it.

Can you mix it with water and syrige it into his mouth?

My fiance's horse is a rather picky eater. And he's on joint supplement. what we did was we just gave him applesauce first, so he would get a taste for it and want more. Then we would mix in whatever supplement. Sometimes he won't eat it, so i put it in his feed bowl where he normally licks it (if there's no food in there) He'll have that and then have some of the applesauce. If he's still picky about it, i put some more grain in his bowl and put a spoonful on top of his grain. If that doesn't work, i'll add a handful of grain into the applesauce, so it's kinda chucky, and he'll eat that right up.

Another thing we do sometimes is dip a carrot into the supplement and give it to him.
