Nutrient Standards

In 2002, a new feed evaluation system was introduced in Denmark. This system is based on the physiological energy value of the nutrients and on their standardised digestibility.

The new system introduced two new feed units replacing the old feed unit: FUgp (feed units for weaners, growers and finishers) and FUsow (feed units for sows).

In practice, the Danish energy evaluation is based on:
1. Chemical analyses of water, ash, crude protein and crude fat
2. In vitro digestibilities at ileal and faecal levels
3. Energy values of nutrients based on "potential physiological values".

The protein evaluation system is based on the standardised ileal digestibility for each amino acid.

The standards were revised in October 2017.
