Facilitating the absorption of trace elements<br />
To ensure the expression of the coat’s full spectrum of colours, the cells need to have a sufficient<br />
quantity of the amino acids tyrosine and phenylalanine, which are precursors of the hair pigment<br />
melanin. An inadequate intake will lead to changes in the colour of the coat.<br />
Copper plays an important role in maintaining the quality of the skin and coat, as an essential<br />
co-factor in tyrosinase, the key enzyme in the synthesis of melanin.<br />
The absorption of trace elements (iron, copper, zinc etc) is naturally lower than 30%. The incorporation<br />
of copper in the food in chelated form helps improve its metabolic utilisation in Cockers, whose<br />
coat-related syntheses are highly active, due to its long hair.<br />

Chelated trace elements<br />
The absorption level of trace elements varies<br />
depending on how they are provided<br />
Blood<br />
A chelated trace element is made up of one metallic ion linked<br />
to three amino acids. When trace elements are chelated<br />
the absorption yield can exceed 60%.<br />
