IM Technology™

Purina Mills’ IM Technology™ (Intake Modifying Technology) causes cattle to consume multiple small snacks daily of the supplement, which optimizes the flow of nutrients to the digestive system, thereby increasing forage intake, overall utilization, and cattle performance.


IM Technology™ creates the right balance of nutrients, ingredients and manufacturing techniques to develop products ideally suited to the animals’ life stage and the quality of existing forage. IM Technology™ triggers in the animal both a prehensile and a metabolic response.

IM Technology™ impacts both how the animal ingests nutrients (i.e., through licking with its tongue, or eating with its teeth) and the amount consumed. The net result is optimized nutrient intake throughout the day through multiple small snacks. We know that on a 24-hour basis, cattle on Accuration/Cattle Limiters, Sup-R-Lix, or Sup-R-Block will come to the feeder between three and 10 times per day, depending on pasture size and forage quality. Multiple small snacks daily provide the necessary ingredients beneficial microflora (or "bugs") need to grow in number and efficiency. The more "bugs" present and the more efficient they are in digesting the forage, the more your cattle’s needs are met from your grass or hay and the less supplemental feeding.

For Controlled Intake Systems utilizing the IM Technology™ to be effective, Purina Mills has established the following criteria. They must:

  1. Provide performance equal to or better than hand-feeding programs.
  2. Limit intake effectively. As forage quality improves, intake of the supplement must go down; as forage quality declines, intake of the supplement must increase to meet animal need.
  3. Provide a nutritional package (protein, energy, macro minerals, trace minerals, vitamins) to meet the needs of the cow or stocker when grass or hay won’t.
  4. Deliver nutrition with flexibility to meet cattle needs and producer goals.
  5. Increase the amount of time your cattle spend grazing the greatest resource you have — your grass or hay.
  6. Increase grazing distribution of your cattle. Simply put, your cattle need to be utilizing all of your pasture, not just part of it!
  7. Decrease your delivery cost compared with that incurred by hand feeding. This means we need to be able to decrease factors such as labor and vehicle cost (depreciation, fuel, maintenance, increase vehicle life, etc.).
  8. Increase carrying capacity on high-quality pastures for stocker cattle.
  9. Increase forage intake on poor-quality forage.
