Effective nutrition products designed to support animal health, digestion, performance, and productivity.
FS Fusion is an economical solution for dairy producers looking to protect their cows from compromised feed quality. Mold, yeast, and mycotoxins cause a multitude of issues such as digestive disorders, immune suppression, and lower reproductive performance. With the propriety combination of yeast, bentonite, and cell wall, FS Fusion protects the rumen and supports high production through healthier cows.
Emenda is built to defend the modern dairy cow from antinutritive factors. A strategic combination of yeast extract, bentonite, and Bacillus subtilis help guard against mold, yeast, and mycotoxins commonly found in ensiled forages and grains. In a University of Missouri study, Emenda reduced Fumonisin, Ochratoxin, T-2, Vomitoxin, and Zearalenone concentration compared beyond that of three leading competitive products. Emenda is designed to protect the rumen and hind gut to support health and high production.
Emenda+ is built to make our base Emenda product even more effective against anti-nutritive factors. Emenda+ has additional bentonite, and along with yeast extract and Bacillus subtilis the boosted combination helps to guard against mold, yeast, and mycotoxins commonly found in ensiled forages and grains. In a University of Missouri study, Emenda Plus reduced Fumonisin, Ochratoxin, T-2, Vomitoxin, and Zearalenone concentration compared to a leading bentonite competitor. Emenda+ works to protect the rumen and hind gut to promote health and high performance.
RealClose is a custom blend of anionic minerals on a wheat middling carrier blended in a proprietary process with molasses to sweeten the mixture and increase palatability.
A close-up cow’s requirement for calcium increases as it begins to make colostrum. After the cow has calved and starts to produce greater volumes of milk, her demand for calcium continues to increase. Commonly, during the close up period in a cow’s life, their dry matter intake decreases which can lead to calcium deficiency during early lactation and lead to hypocalcemia.
The modern dairy cow faces feed challenges every day and Activ20 provides an economical solution to provide daily protection from anti-nutritive factors. Activ20 protects the rumen and supports high production through healthy cows.
FS Max is formulated to protect against anti-nutritive factors and to support the rumen and hind gut for recovery from insults due to off-quality feeds. The yeast and yeast extract, bentonite, and Bacillus subtilis components are formulated to guard against mold, yeast, and mycotoxins commonly found in feeds. The probiotics and enzymes allow the rumen and hind gut to return to normal function for high production.
Our inoculant product lineup works to optimize silage nutrient retention by supporting anaerobic conditions that allow beneficial bacteria to work effectively—controlling pH levels and bunk heating. At Feed Sources, we are able to provide custom inoculant blends based on your crops and harvest conditions. Inoculating your harvest helps assure you are storing quality, palatable feed for your livestock resulting in less spoilage and waste at the feedbunk.
