The trace minerals zinc, manganese, copper and iron are involved in a wide variety of important physiological

processes. An adequate supply is of high relevance for various parameters of animal performance and health.


  • Reproduction (oestrus cycle, ovarian activity, conception)
  • Formation of epithelial tissue and structural proteins (skin, horn, egg shell, gut cells)
  • Immune system
  • Regeneration processes
  • Skeletal development (bones, cartilage)
  • Hemoglobin synthesis
  • Metabolic functions


Critical situations

The challenge of modern trace mineral feeding is to meet the requirements of high-performing animals and, at the

same time, avoid excess dosage and excretion of metals.  Although essential trace minerals are added to the diet

according to official recommendations, suboptimal supply situations occur in practice. Along with a constant increase in the requirements of high-performing modern breeds, there are specific situations leading to a higher demand for trace minerals:

Prenatal intra-uterine growth

  • Regeneration after farrowing / calving
  • Trace mineral loss via milk
  • Reduced feed intake  
  • Lower absorption capacity with increasing age
  • Weakened immune system

Stress factors (heat, feed change, relocation, stocking density, etc.)

    Anemic situations in young animals

A secondary deficiency can result from the presence of organic compounds or other minerals that reduce the

absorption of essential trace minerals. These antagonisms are pronounced with increasing trace mineral levels in the feed and when metals are present in ionic form in the upper gastro-intestinal tract (GIT).

Trace mineral Important antagonists

E.C.O.Trace® glycinates – Mode of action

The form of chemical binding has a significant effect on susceptibility to antagonisms and thus on the bioavailability of trace minerals in the GIT. The metals in E.C.O.Trace® are bound to the amino acid glycine. Compared to traditionally used inorganic forms, the metal-glycine complex offers an effective way to provide trace minerals in a less reactive, highly efficient form:

  • Higher vitamin stability in premixes Superior stability of metal-glycine complex at low pH
  • values in the upper GIT (rumen, stomach) → “Protection “and less release of metal ions
  • Less complex formation between metal ions and other dietary compounds (e.g. phytate)    
  • Reduced antagonistic effects in absorption between metal ions
  • Effective transport to the intestinal wall and beneficialabsorption rate of trace minerals


E.C.O.Trace® glycinates have been successfully used in feeding high-performance animals since 2007. The superior

absorption rate of trace minerals from E.C.O.Trace® has been proven in several scientific studies showing higher

values in bioavailability compared to sulfates.

A number of advantages arise from the excellent bioavailability of E.C.O.Trace® minerals:

Improved trace mineral status and safe supply in situations of increased demand

     Reduced risk for subclinical deficiency symptoms      

     Lower excretion of metals



Glycine – The smart binding partner

The use of glycine in the production of E.C.O.Trace® allows several advantages compared to other forms of trace

mineral complexes: The use of synthetic glycine guarantees optimal  availability of binding partners for a high degree of metal complexation Glycine is the smallest amino acid occurring in nature and therefore allows the highest metal content for low inclusion rates Water solubility enables universal application

A well-designed chemical composition allows a better routine control of quality


The right solution for every demand

E.C.O.Trace®  glycinates are produced in a standardized process based on Biochem᾿s extensive experience in

organically bound trace minerals developed over more than 20 years. The Biochem E.C.O.Trace® product range deliversn the essential trace minerals, zinc, copper, manganese and iron, in high quality. In a special drying process, a granulated structure is generated to offer the following advantages:    

  1. Homogenous particles
  2. Good flowability for optimal dosing
  3. Minimized dust formation for maximum working safety
  4. Low moisture content
  5. Excellent mixing behavior



Biochem E.C.O.Trace® glycinates are convenient for the production of all kinds of premixes, mineral and mixed

feeding stuffs. Along with E.C.O.Trace® single additives, we offer various combination products to provide a wide range of animal specific solutions. Regarding animal nutrition as a holistic process enables us to develop reliable and intelligent concepts for you and your customers.
