Is your zinc working where it matters?

The problem

Zinc (Zn) is essential for the proper physiological functioning of animals, but its absorption in pigs is relatively low (around 20%) due to the presence of anti-nutritional compounds such as phytic acid (phytate) in the diet.

These molecules form insoluble and non-absorbable complexes with free Zn²⁺ ions in the digestive tract, which hinders the absorption of zinc. Zinc that can't be absorbed by the pig is excreted in its faeces and accumulates in the soil, harming microorganisms and plants, and contaminating water.

The ban on pharmacological doses of zinc oxide (ZnO) in piglet feed prompted the search for new sources of zinc to ensure that their growth and health performances are maintained while complying with regulatory standards.

The CAPMAG® solution

CAPMAG® Zn is an innovative solution to improving the growth and health of pigs, while ensuring an efficient and responsible use of zinc in animal nutrition.

Developed in France by Terresis (formerly TIMAB Magnesium), CAPMAG® Zn’s effectiveness lies in the physical protection of zinc by magnesium, which allows zinc to be released very gradually, peaking in the final phase of digestion.

Effectiveness

In vitro tests* have demonstrated:

Improved Zinc absorption with CAPMAG® Zn Compared to ZnO, ZnSO4 and Zn-Glycinate.
CAPMAG® Zn contributes to a positive modulation of the gut microbiota.

Trials in weaned piglets** have demonstrated:

Improved digestibility of Zn, P and dry matter compared to ZnSO4.
Better support for digestive health (microbiota, enzymes, faecal scores) compared to ZnSO4 and an innovative source of ZnO.
Improved growth performance (average daily gain, feed conversion ratio, feed consumption – up to +2kg body weight at the end of post-weaning) compared to multiple doses of ZnO, ZnSO4, an innovative source of ZnO and Zn-Glycinate.
Significant reduction in zinc excretion in faeces compared to ZnO.
