Dr. Slagle's been a part of Ramaekers Nutrition, Since 1972.
In 1972, Dr. Slagle met Dr. Ramaekers at a large animal practice. They became friends with mutual interests and would attend the AAEP (American Association of Equine Practitioners) conventions each year.
Transfer Factor
In 1999, a small animal practitioner introduced Dr. Slagle to a human product called Transfer Factor (TF). Dr. Slagle decided to try this so-called "miracle treatment" in his large animal practice.
He had three extremely sick foals visit his practice over a three-week period. Each had various infections that had a 10% chance of survival. He used standard treatments combined with Transfer Factor Plus (TF). And to Dr. Slagle’s astonishment, all three patients responded in record time and were all saved. He was sold. This so-called "miracle treatment" Transfer Factor (TF) was the real deal.
Synergistic Effect
Dr. Slagle called Dr. Ramaekers, as he knew he was a master formulator. Once Dr. Ramaekers realized the potential for Transfer Factor (TF), he combined it with his already successful array of products and saw its synergistic effect on helping patients.
Ramaekers Nutrition
In December 1999, at an AAEP (American Association of Equine Practitioners) Convention, Dr. Slagle and Dr. Ramaekers officially began their adventure of formulating Transfer Factor Plus (TF) nutritional supplements for animals.
Getting the Word Out

Product Background
