Transfer Factor Technology

Medicine is the Science of Disease, and Nutrition is the Science of Health.

Trust transfer factor technology to optimize your commercial livestock's immune system function in bovine health. While many products use single rudimentary ingredients known to aid immune health, Ramaekers Nutrition delivers the only immune support products harnessing transfer factor supported by a unique, field-tested, and patented blend of essential nutrients and potent nutraceuticals. See our Mission.

Patented Formulas

Our transfer factor technology is derived from a proprietary blend of bioactive peptides. These bioactive peptides are extracted from bovine colostrum and egg yolks. This blend combines unique plant-derived heteropolysaccharides, lactic acid-producing probiotics, and highly bioavailable micronutrients.

The synergy of this combination of ingredients enables the “immune intelligence” (the body’s ability to recognize and remove harmful cells) in our formulas to assist your cattle in naturally producing an effective, rapid, and appropriate immune response.

Immune Primer

Like colostrum (or first milk), which transfers vital immune knowledge from mother to newborn, our Newborn Immune Primer and Adult Immune Primer formulas educate and activate the function of the mother and calf’s immune cells within hours and without side effects using our patented transfer factor technology.

Herd Health

While Medicine is the Science of Disease, we feel that Nutrition is the Science of Health. The bottom line is that regardless of your herd health program, enhanced immune function made possible by Ramaekers Nutrition’s orally-delivered formulas improves your current herd health results. Our bovine health formulas will help your nutritional program and bolster profit potential in the following ways:

  • Significantly fewer treatments and death loss
  • Better response to existing nutrition programs and health protocols
  • Maximized state of wellness for better gain and reproductive outcomes (see reproduction and fertility)
  • Improved genetic expression by addressing sub-clinical disease issues
Bovine species. We strongly advise incorporating our natural supplements into a proven herd health program, including appropriate vaccine protocols, rations, and, most importantly, mineral and trace mineral supplements.

Bovine Health: Count on Bovine Immune Primer and Preconditioned Premix Formulas to put money in your pocket

As cattle respond to stress across key production stages, their immune systems are weakened, predisposing them to infection and disease. Our bovine health products, Newborn Immune Primer, Adult Immune Primer, and Preconditioned Premix formulas (learn more about our sustained release formulas), act quickly to educate and activate immune cells, helping newborn calves, weaned calves, breeding stock, cattle for transport, and cattle on feed to wage an appropriate immune response to stress and enabling their immune systems to fight the real threat of infection and disease.

State of Wellness

With stress in check and “gap immunity” in place, cattle sustain a state of wellness, allowing bovine health nutritional programs and standard health protocols to be more effective. We feel that livestock that maintain a better state of sub-clinical health will be more able to maximize and express their genetic potential.

Advancements in technology often change the methods we use to solve problems.

Bovine Health. From time to time, there is an advancement in technology that changes how we think about a problem. In the cattle business, this technology is immunotherapy. Natural Immunotherapy is just such a technology.

Natural Immunotherapy is the science that educates the cattle's own immune system to fight viral and bacterial infections. For more than 50 years, Ramaekers Nutrition has developed patented natural products that educate and enhance immune system function in stressed cattle.

Patented formulas provide technology and opportunity.

Our patented formulas provide the technology and opportunity for newborn and adult ruminants to absorb the equivalent immune information and education found in six gallons of colostrum in an easy-to-deliver form. Our field veterinarians use these products as adjunctive and preventative therapy in treatment programs with or without antibiotics. The key to this approach is modifying the animals' response to stress (cortisol production) and maintaining a highly functional and vigilant immune system.

Reduce Cortisol

The key to this approach is to modify the animals' normal response to stress (increased cortisol production), thus maintaining a highly functional and vigilant immune system. Our studies prove that we can reduce the excessive cortisol release (by 42%) brought on by stress using a safe and economical product conveniently delivered at all stages of production.

Integrating Supplements with a Herd Health Program

Natural Immunotherapy

We strongly advise incorporating these natural supplements into a proven herd health program, including appropriate vaccine protocols, rations, and, most importantly, mineral and trace mineral supplements. We have found in our case studies that by integrating our supplements with a herd health program, we have seen significant results with the following:

  • BVD (Bovine Viral Diarrhea)
  • BRD (Bovine Respiratory Disease)
  • Pneumonia
  • Shipping Fever
  • Stocker and Feeder stress
  • And many other health issues

Health and Vigor

Trials repeatedly have shown an improvement in Health and vigor that translates to

  • Decreased sickness to below 6%
  • Decreased death loss to .2-1%
  • Increase in weight gain and feed conversion
  • Decreased days on feed
  • Increased performance ↑efficiency with a 15% improvement
  • Increased yield ↑2-3%
  • Increased Prime and Choice grades
  • For “All Naturals,” Increased Health results in an increased number of cattle “on the program” to receive the all-natural bonus at harvest.

Birth to Harvest

In the “all-natural” business of buying single-source, preconditioned cattle, our formulas help control BRD (Bovine Respiratory Disease). Since 46% of healthy cattle have Mycoplasma in their respiratory tracts, identified via PCR testing, prevention is critical to improving immune function before stress and disease onset. For best results, it is essential to put all cattle on the program to maintain Health from birth to harvest.

Ramaekers Nutrition

For more than 50 years, Ramaekers Nutrition has focused on researching and developing natural immunotherapy supplements. See Bovine ResultsCanine ResultsFeline ResultsEquine ResultsLivestock Studies, and Companion Animal Studies.

Ramaekers Nutrition’s products reflect a culmination of global research and clinical experience. Dr. Ramaekers is passionate about improving animal welfare. He is proud to be on the cutting edge of veterinary medicine (meet our veterinary team) and nutrition. Learn more about Ramaekers Nutrition.

Unique Formulas

Our unique Newborn Immune Primer, Adult Immune Primer, and Preconditioned Premix formulas help educate and boost the immune system for overall health and vitality. Our products can up-regulate and down-regulate an immune system. Thus, they are actual immune modulators. Immune modulators “prime” the immune system to react appropriately. Only when needed and will not overstimulate or activate without an external stimulus such as a disease-causing organism.
