Use of highly available raw materials for a minimal environmental footprint


The use of AMINOTRACE organically bound trace elements developed by SCHAUMANN allows the heavy metal pollution of soils to be substantially reduced. The extremely high bioavailability of these trace elements results in reduced excretion of heavy metals by animals.

 

Zinc and copper are among the essential trace elements and as such perform important physiological functions in animal feed. However, being toxic heavy metals they also present a risk to the natural environment.

 

Zinc and copper are supplied via animal feed, and animals excrete any excess. When liquid manure is spread onto agricultural land as fertiliser, these excreted heavy metals are introduced to the soil, where they can create an environmentally relevant heavy metal load.

 

The use of AMINOTRACE trace elements allows the heavy metal pollution of soils to be substantially reduced. Organically bound trace elements (trace element chelates) are associated with substantially higher absorption rates in the digestive tract compared to oxides and sulphates.

 

Due to the high availability of these trace elements in the digestive tract of animals, their supplementation can be optimised and excretions of heavy metal be reduced by up to 50%.

 

Experiments have shown that partial digestibility of zinc, copper and manganese was increased by 38%, 34% and 141% respectively compared to the digestibility of sulphate compounds. This means that a larger portion of the supplied trace elements was in fact utilised, resulting in copper and zinc excretions from animals for fattening being reduced by 40% and 60% respectively.
