Trace elements: Essential and indispensable

Trace elements are essential micronutrients required by all animals. Insufficient amounts in the feed can have severe consequences including lower feed intake, growth reduction, impaired immune function, and reduced fertility in the animal.

In the past, trace elements were added to the feed in the form of inorganic salts such as sulfates and oxides. Only a limited percentage was absorbed by the animal – the major part ended up in the manure. Quite a waste both financially and environmentally.

Today, organically-bound trace elements such as glycinates are commonly used in animal feeds, since they show higher bioavailability. This results in increased animal performance and better animal vitality and productivity. BASF glycinates can be dissolved directly in water and do not need to be dissolved beforehand. Since they have less potential to build complexes with phytate a higher absorption rate by gut mucosa and even a higher efficiency from supplemented phytase can be expected.

Benefits of BASF's Iron-Glycinate

  • Provide essential micronutrients required by all animals
  • Highly efficient based on high degree of complexation
  • Good solubility for optimal absorption
  • Easy to handle and high bioavailability
  • Patent protected

With glycinates, potentially smaller quantities are needed to supply the animals’ net needs, and the environment benefits from less excreted trace elements. By using glycine, the smallest amino acid occurring in nature, it is possible to form the smallest amino acid trace element complex with the highest mineral content. Glycinates are therefore a great leap forward – but BASF leapt further.

With BASF glycinates, you are getting trace elements in a form that is easy to handle, highly efficient and guaranteed to fulfill animal and customer requirements.


Iron is responsible for oxygen binding in blood cells. It is also the main ion in many enzymes and plays a central role in anti oxidative processes. Lack of iron leads to exhaustion, reduced performance and insufficient generation of hemoglobin.

Good Solubility - For optimal absorption

BASF glycinates show an excellent water solubility: Water solubility was measured according the OECD method of analysis no 105 with a water temperature 20°C, creation of saturation by stirring for 24 h. The amounts of BASF glycinates which can be solubilized without sedimentation, you can find in the BASF Animal Nutrition Glycinates-Brochure at our download center.

The way to your animals' vitality is through their gut

BASF glycinates are suitable for all types of premixes, mineral and mixed feeds. The flowability and mixing behavior of the product is excellent and eases homogeneous distribution in all types of feed.

The EU maximum contents are given per kg of feed based on the assumption that the animals are fed mainly with complete feed. If a supplementary feed is given in addition to the basic ration, the amount of trace elements contained has to be taken into account.

Total maximum content of Iron in mg/kg of the complete feed in accordance to EU regulation EC No 2330/2017.

Please note that the dosage must be calculated on an element equivalent basis.

Dosage recommendations

Maximum content of Iron in mg/kg of the complete feed or in mg/day
Ovine 500 (total1)
Bovines and Poultry 450 (total1)
Piglets up to one week before weaning

250 mg/day (total1)

Pet animals 600 (total1)
Other species 750 (total1)

1 (The amount of inert iron is not to be taken into consideration for the calculation of the total iron content of the feed.)
