Trust Transfer Factor Technology

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

Trust Transfer Factor Technology to optimize immune system function in your show cattle reproduction. While many products use single rudimentary ingredients known to aid immune Health, Ramaekers Nutrition delivers the only immune support products harnessing Transfer Factors supported by a unique, field-tested, and patented blend of essential nutrients and potent nutraceuticals.

Transfer Factor Technology

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.

Field Studies and Research

Years of field studies and research have led to a livestock formulation showing overwhelming improvement in herd health, stress reduction, vaccine enhancement, fertility, and reproduction (see reproduction and fertility).

Herd Health

We advise incorporating these natural supplements, Newborn Immune Primer and Adult Immune Primer, 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:

  • Increased egg count
  • Improved embryo grade
  • Increased conception and implantation
  • Improved spermatogenesis
  • Reduced morbidity and mortality of newborns

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

Show Cattle Reproduction. 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.

Dr. Ramaekers and his field veterinarians have a particular interest in exploring and researching the following areas:

  • Transportation stress reduction to help maintain immune function
  • Enhanced embryo quality and increasing numbers produced
  • Improving embryo transplantation and recipient’s conception
  • Improving spermatogenesis leads to improved volume and concentration
  • Reducing the incidence of Mycoplasma
  • Reducing the incidence of BVD (Bovine Viral Diarrhea), and BRD (Bovine Respiratory Disease)
  • Decreased shipping fever
  • Increasing weaning weights
  • Decreased calf scours
  • Decreasing E.Coli diarrheas
  • Improved viability of newborns

Show Cattle Reproduction Animal 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 animal health protocol, enhanced immune function made possible by Ramaekers Nutrition’s orally-delivered formulas (learn more about our sustained release formulas) will enhance your current herd health protocols. Our 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 overall state of wellness for better gain and reproductive outcomes
  • Improved genetic expression by addressing sub-clinical disease issues

Show Cattle Reproduction Natural Immunotherapy

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 animal’s 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, Newborn Immune Primer and Adult Immune Primer, 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 we know that 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.

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.
