I use this for my growing 2 yo colt by Secret!
I have a phenomenal colt by a wonderful breeding line and I want to really preserve my investment and make sure he grows strong! Number one, the packaging was great and the product came quickly and Iâve been feeding this for about a month and a half. I have seen significant growth spurt. Will probably continue to feed to make sure he develops nicely and sturdy! Horse eats it with no problem!!! A very important supplement for a growing boy! Heâs going to be roughly 17.1h so making sure he develops strong bones to make him last as long as my 23 yo GP horse!!!

Horses like it!
Itâll take awhile before thereâs any noticeable difference but weâre pretty happy with this. Easy to open tub, with a handle. Pellets are well made, without many fines. Horses are pretty happy and like it quite a bit. Dosing instructions are easy to follow on the tub.

Good stuff.
It’s hard to know what supplements are doing their job, but I’d say trace minerals like this are an important part of any aging or foals regimen, depending on the feed you’re giving. Since it’s in pellet form it’s pretty easy to give to the picky eater if mixed with their usual feed.

Itâs a marathon not sprint
I got this quite awhile ago but not more than a few weeks maybe? Honestly canât remember, but supplements take longer to show visible results than you think. Itâs not like an antibiotic, where you see signs itâs working in a day or two, it is a longer term solution. Itâs a lot like human vitamins and supplements, itâs a process. The minis are doing well so far with it. I am pleased thus far, it is palatable to them and they accept it readily

Pellets
Love that these are pelleted! Easy to give. They have a certain smell that reminds me of mineral blocks. Very convenient product. Comes with a scoop. Blessings!
