Targeted IGF-1 Nutrition for Livestock Performance

Nature’s Formula IGF-1 feed additive is designed to optimize muscle growth, fertility, and tissue development in cattle, sheep, goats, and wildlife.

What is IGF-1 and Why Does It Matter?

IGF-1 (Insulin-like Growth Factor) plays a vital role in animal development. Our feed additive mirrors the nutrient profile of green vegetation, supporting:

  • Muscle growth and marbling

  • Fertility and reproductive health

  • Tissue repair and immune support

  • Antler development in deer and elk

Built on Research. Proven in the Field.

Each formulation is based on university-led nutrition studies, verified inclusion rates, and real-world results from producers across the country.

No Added Copper, Safe for All Ruminants

Nature’s Formula IGF-1 feed additive contains no added copper, allowing feed manufacturers and nutritionists to set appropriate copper levels for copper-sensitive species like sheep, llamas, or camels. Many additives pose risks due to copper content. Nature’s Formula provides a safe alternative — scientifically calibrated for all biological ruminant types.

Formulated with Superior Green Vegetative Sources

Nature’s Formula IGF-1 was granted permission by the Texas State Chemist Office, under Chapter 61.29 of the Texas Administrative Code, for its formulation based on superior vegetative sources. Premix formula labeling complies with the Texas Commercial Feed Acts 141.051 or 141.052.

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
