Gro 'n Win®

Not all forage is created equal. That's why GRO 'N WIN® is the perfect ration balancer to complement your horse's forage. Created to be fed as a stand-alone feed or a supplement to your horse's daily grain diet, it is formulated with a precise balance of amino acids, vitamins and minerals for easy digestion and absorption. GRO 'N WIN® is highly concentrated, so you feed less of it, allowing your horse to eat more naturally. See for yourself how much you can save with our GRO 'N WIN® cost calculator. Ideal for growth, reproduction, performance, and maintenance horses, GRO 'N WIN® along with forage will supply your horse with all the essential nutrients it needs without excess calories or use of additional supplements.

Forage values are suggested intakes based on good quality forage. The quality and digestibility of the forage is variable and dependent on the maturity of the plant at harvest. Horses older than 6 months should be fed at least 1% of the bodyweight as forage to maintain gut health.

When possible, have your forage analyzed to estimate quality and digestibility.

If additional calories are needed do the following:

  1. Add ULTIMATE FINISH® by BUCKEYE® Nutrition.
  2. Incorporate the recommended amount of specially designed feeds by BUCKEYE® Nutrition to meet the unique energy demands of your horse.

Always maintain a clean, fresh water supply.

Make salt available free choice.


OLA maintains weight & is still energized after competition

Meet OLA Loki and owner Bonnie! Loki is insulin resistant, but still competed 665 miles in competitive trail, endurance and limited distance endurance to win the regional championship, Part Arab championship, the Charles Phillips Versatility award and the AHDRA versatility award.

"While he is competing, Loki gets Cadence, which he LOVES, and GRO 'N WIN. He was able to maintain his weight and remain full of energy even after three days in a row of competing and going week after week. When he is not competing he just gets GRO 'N WIN. Thanks you for taking the time to do the research and produce great products for the performance horse."

Koda's hoof quality & coat condition improve with GRO 'N Win

Meet Koda, a 20 year old Quarter Horse. He's retired from barrel racing but still active with his owner, Hallee. After just one month on GRO 'N Win, his topline, coat condition and hoof quality have improved drastically, and he is feeling like a 4 year old again!

Charlie's coat shines with GRO 'N Win

I love your product Gro 'N Win! I adopted a 2011 standardbred gelding in March, and although he was in good condition for a stockyard rescue, he still was on the thin side with a dull/scraggly coat. Even after a month or so of TLC and being on a regular feeding program, Charlie was lethargic with a dull coat, so I called my local pet pharmacy/feed store and asked for suggestions. They put me in contact with a Buckeye nutritionist, and she suggested Gro 'N Win. Within a week, Charlie started to shine up, muscle up and had so much more energy! He looks fantastic - and he LOVES it. Charlie and I thank you so much for such a fantastic product!
