Slow Feed Hay Feeder


The OptiMizer combines the best of slow feed netting with the convenience of a multi-bale feeder.

It holds two small square bales or up to 150 pounds of hay from large square or round bales. Best of all, it takes less than 60 seconds to fill. Simply un-clip the slide arm, open the top, add your hay, cut and remove the twine, slide the net back over, and re-clip the slide arm. That’s it! You’ve slow fed two bales of hay in under a minute.



Get maximum durability. The manger is made from LLDPE, the same polymer used to make playground equipment, and has a stainless steel assembly mounted inside.

Reduce the risk of injuries with corners that have been rounded or bevelled to create smooth, safe edges.

Be kind to their muzzles. The netting is made from knotless nylon, proven to be reliable yet gentle.


Enjoy smooth, one-handed operation with the patent-pending slide arm.

Help them find every last bit. Slow feed netting hangs freely inside the feeder so it can conform right to the bottom.


Allow as many as four horses to comfortably eat together around an OptiMizer.

Ensure good drainage on any terrain with 12 holes in the bottom of the manger.

Prevent good hay from going to waste. With an OptiMizer, the tiniest bits aren’t lost to the ground but remain within the OptiMizer for your horses to clean up as they feed.

My horse is a 17 year old, off-the-track thoroughbred who lives outside all year. She's a hard keeper, but by getting her the right amount of hay, whenever she wanted it, it was the first winter she didn't need an extra blanket or grain.

We use 3 OptiMizers for our herd of 8 horses. We fill them about once a day, even on the worst days, and have found ourselves going through a lot less hay. I'm confident our OptiMizers will pay for themselves in the amount of money we've saved in otherwise ruined hay.

I've always had slow feed bags. I needed five or six a day to feed three horses. Last winter with the OptiMizer I could slow feed two bales in one place. This saved me a ton of time not having to refill bags everyday, plus I noticed it was way cleaner in the spring.
