Our Story
From Ranchers to Nature’s Formula
Ranchers Performance Mineral, owned by Cody Cauley in San Angelo, Texas, is proud to bring you top-quality mineral solutions. Initially crafting our personal cattle mineral, we’ve grown to manufacture the innovative Nitro sheep mineral fortified with Nature’s Formula IGF-1, producing record-setting growth for sheep entrepreneurs Justin Tremble and Dax Dietrich.
Dax, a forward-thinking rancher, imported elite sheep embryos from Australia, incorporating Nature’s Formula into commercial feeds manufactured by Livestock Nutrition Center across America, including Oklahoma.
Today, we’re proud to launch Grass Factor IGF-1 Cattle Mineral Supplement, a product fortified with Nature’s Formula and now insured, produced, promoted, and distributed under the Nutra Blend umbrella.
Letter From Our CEO
I would like to invite all feed manufacturers and livestock nutritionists in Nature’s Formula IGF-1 with your standard pre-mixed feed additive utilizing Nature’s Formula as your primary feed additive to fortify your feeds.
Overall Animal Nutrition research has focused on the science of key vegetation that stimulates growth factors in ruminants with optimum blueprint of each individual animal, from conception to consumption.
We have provided several QR CODES linked to educational videos comprised with clinical data from Texas A&M University, Kansas State, Nebraska, and several global animal science institutions on the daily dietary effects of IGF-1 growth serums from high levels of Vitamin A in finished feeds for groups of cattle, sheep, goats, bison, buffaloes, camelids, and all species of antlered deer.
Again, I invite you to evaluate the educational information, scientifically formulated and product information displayed on the formulation charts within our brochure, exhibiting levels of vitamins, biotin, folic acid, organic zinc, organic manganese, and organic selenium. There is No Copper in our additive, making it attractive for sheep feeds and other copper-sensitive ruminants. Nature’s Formula IGF-1 feed additive is manufactured and distributed by The Nutra Blend Corporation as a floor stock item, readily available to every independent feed manufacturer in America.
Sincerely,
Mark Jolly
