AnimineThe following changes will be implemented:

- Maximum copper supplementation levels will be even more restricted in piglet feeds:

Before After
Piglets up to 12 weeks: 170 mg/kg Cu (total) Suckling and weaned up to 4 weeks after weaning: 150 mg/kg Cu (total)
From 5th week after weaning up to 8 weeks after weaning: 100 mg/kg Cu (total)

- Oxidation state and copper concentration in each compound will be more strictly defined:

Oxidation state Minimum Cu content
Copper(II) oxide Cu2+ 77 %
Copper(I) oxide (CoRouge®) Cu+ 73 %
Copper(II) carbonate Cu2+ 52 %
Copper(II) chloride Cu2+ 36 %
Copper(II) diacetate Cu2+ 31 %
Copper(II) sulphate Cu2+ 24 %
Copper(II) chelate of glycine (solid) Cu2+ 15 %
Copper(II) chelate of amino acids Cu2+ 10 %
Copper(II) chelate of protein hydrolysates Cu2+ 10 %
Copper(II) chelate of glycine (liquid) Cu2+ 6 %

- Copper compounds will not be used in water for drinking.

With such progress in the definition and characterization of supplemented trace minerals, European regulation helps the feed industry to select the best copper source for optimal bioavailability and intestinal health. CoRouge®, as a unique form of copper(I) oxide, has been authorised in the European Union in December 2016 with latest requirements on proofs of identity, safety and efficacy.
