not 2.91 % DM (basal diet + 2% from a supplement).
It was concluded that the highest no-effect-level
of lysine for puppies was 2.91% DM (energy density
4156kcal/kg or 17.39MJ/kg). This is equivalent to
7.0g/1000kcal (1.67g/MJ) or 2.8% DM (at 4kcal/g DM) and
this is therefore the FEDIAF maximum for puppy growth.
