Beef Cattle Nutrition Built on IGF-1 Performance
Every animal featured on this page was raised on feed fortified with Nature’s Formula IGF-1. These formulations are designed to meet the unique needs of bulls, cows, calves, and show cattle at every stage, using data-backed inclusion rates from agricultural universities.
Each formula is identified by a unique code, designed to support IGF-1 activity through Vitamin A-driven fortification for muscle growth, fertility, and lifelong tissue development.

Sel-Plex Alltech’s selenium, a proprietary organic form of selenium yeast is an excellent dietary source of selenium manufactured to mimic Mother Nature’s natural form, found naturally in plants and selenium deficiency is prominent throughout most of America
Enriched with Yea-Sacc Signature Yeast Culture promoting digestion and utilization of nutrients, while providing the right nutritional platform needed to sustain higher milk production, maintain condition in high producers, reduces fluctuation in pH and keeps rumen microbes steadily active, which speeds feed digestion and rumen turnover, allowing greater intake, promotes the growth of fiber-digesting bacteria in the rumen, thereby supporting the rate and extent of forage breakdown, stimulating the activity of the bacteria that convert lactic acid to propionic acid, promoting rumen stability, avoiding the wide variations in rumen pH that interfere with fiber digestion and feed intake with highly cost-effective returns through greater performance.
