Sustained Release Feed Supplements

Phased-Release Feed Supplement. Achieve maximum immune stimulation with our Phased Release Immune Primer

Sustained Release Immune Primers

Our Sustained Release Immune Primers make it easier to administer this orally delivered product and achieve maximum immune stimulation.

When we study the entirety of our field research, it is clear that we've proved the best results for immunotherapy require two consecutive days of treatment with our approach to immunotherapy. The process of stimulating bovine immune cells two days in a row is like giving a booster vaccine.

Cost Effective

Running through the processing chute or handing the newborns twice adds expense and stress. Ramaekers Nutrition developed a delayed or sustained release immune primer delivery system.


We recommend giving this formula on day one. It slowly releases the active ingredients in the intestinal tract over 36 to 48 hours.

Follow up treatment

Repeat the dose of our immune primer in 12 to 14 days. This schedule enables the best long-term active immune response. And builds the best vaccine-induced antibody levels.
