What Makes FORCO® Feed Supplement Digestive Fortifier Different?


FORCO LLC is located on the eastern plains of Colorado near the town of Flagler where it first got its start over 30 years ago in 1982. FORCO is a family business owned by David & Lynette Frank.

FORCO initially started in the hay business making a product that would help prevent mold and heating in higher moisture baled hay. Interestingly the name FORCO is derived from the initial hay product of forage (FOR) conditioner (CO). The hay product was a bit different than what the FORCO® Feed Supplement Digestive Fortifier is today though the concept is the same to improve feed.

At the same time David and Lynette were producing the FORCO hay product they owned and operated a race horse training stable for Thoroughbred and Quarter Horse race horses. In 1984 they started researching and studying the use of the ingredients in the hay product for use in a digestive supplement for horses.

An in-house product was later developed from this research and used on the horses in the training center. The changes and results in the race horses were remarkable! In 1986 FORCO Feed Supplement was introduced into the horse market. FORCO’s product marketing has always been about result-driven products with appreciative customers versus elaborate advertising and flashy promotions. The business has been built by customers using the product, observing changes in the horses, being impressed with the results and ultimately spreading the word about FORCO® Feed Supplement Digestive Fortifier.

How Is Forco Different From Other Yeast Products On The Market Today?

FORCO® products are one of a kind products. They are one of the few pure and all-natural products on the market. They are dependable, stable, and safe. They do not contain live microbial or live-cell yeast due to their perishability and inconsistent performance. They have no carriers or fillers and there are no supplemental vitamins, minerals or proteins like many other digestive products on the market today contain.

Most digestive aid products are effective only in the foregut or early portion of the digestion system. This is especially true of microbial products. FORCO® is unique because it is designed to be effective throughout the entire alimentary system from the mouth through the colon.

This is a critical consideration for horses because its the cecum portion of the hindgut that digests most of the forage fiber (hay and pasture) and carbohydrates where the colon then absorbs and/or synthesizes vitamins, minerals, volatile fatty acids and amino acids. Because it addresses the entire digestive process, horses respond to FORCO® when they do not respond to other digestive aids.

Can All Horses Benefit From FORCO?


Yes! FORCO Feed Supplement Digestive Fortifier is a product that addresses the problem of providing proper bacterial populations and fermentation in the horse’s digestive tract. FORCO uses highly effective yeast cultures and digestive enzymes in making FORCO Feed Supplement Digestive Fortifier. FORCO uses a formula that

My sweet 13 yo mare Dottie had started going down hill for no apparent reason. I would have a buffet of grass hay, alfalfa, and grain in front of her at all times and she would eat, a lot, but yet she continued to go down hill. I took her to several different veternarians. They ran blood tests on her and checked her over for other problems, but none of them could come up with a reason that she should be looking like she did. One vet even told me to take her home to die, because that was where the road she was on was leading to. I was heart broken. A good friend then mentioned that I should try a product called Forco. I had not heard of it before, but if she was recommending it, I knew there must be something to it. I started Dottie on Forco in January and you can see from the series of pictures below the difference it started to make for her! As bad as she was it took awhile, but my Forco dealer told me to stick with it. So stick with it I did, and a full 7 months later I have my Dottie back! I know now that Dottie will never be without her Forco! Thank you Forco!

The Solution Section (FAQ)
What is FORCO® Feed Supplement Digestive Fortifier?
FORCO® Feed Supplement Digestive Fortifier is an all-natural digestive supplement for horses that helps establish proper bacterial populations and fermentation in the horse's digestive tract. It uses highly effective yeast cultures and digestive enzymes combined in a single formula. FORCO is a family business owned by David and Lynette Frank, based on the eastern plains of Colorado.
How is FORCO different from other yeast and digestive products?
FORCO® is a pure, all-natural product that does not contain live microbial or live-cell yeast, which the company avoids because of their perishability and inconsistent performance. It also has no carriers or fillers, and no added supplemental vitamins, minerals, or proteins. The formula is only pure fermentation products designed to promote normal microorganism and bacteria populations in the horse's digestive tract.
Why does FORCO work in the whole digestive system instead of just the foregut?
Most digestive aids, especially microbial products, are effective only in the foregut or early part of digestion. FORCO® is designed to be effective throughout the entire alimentary system, from the mouth through the colon. Because it supports the cecum and colon, where forage fiber and carbohydrates are digested and vitamins, minerals, and fatty acids are absorbed, horses often respond to FORCO when they have not responded to other digestive aids.
Can all horses benefit from FORCO?
Yes. FORCO® Feed Supplement Digestive Fortifier addresses the need for proper bacterial populations and fermentation in any horse's digestive tract. The company notes that maintaining a balanced micro flora in the digestive tract is just as important as feeding a balanced ration, so FORCO is meant to complement the feeding program you already use.
What is in the FORCO formula?
The FORCO® formula contains only pure fermentation products, using yeast cultures and digestive enzymes combined for a synergistic effect, so the fermentative quality is greater than each ingredient used alone. It acts as a source of nutrients that feed and nurture the full range of bacterial and microbial populations across the digestive system. It deliberately contains no fillers, carriers, or added vitamins, minerals, or proteins.
How long has FORCO been making horse supplements?
FORCO got its start over 30 years ago in 1982 in the hay business, and the name comes from its original forage (FOR) conditioner (CO) product. While running a Thoroughbred and Quarter Horse race horse training stable, David and Lynette Frank began researching the ingredients for use in a horse digestive supplement in 1984, and FORCO Feed Supplement was introduced to the horse market in 1986.
