Abstract
This trial comprised two groups: a control group and a trial group in which 1 kg Feed ADD-s was added per tonne.

When the pigs were transferred to the finisher unit, the pigs in the trial group had also been given Feed ADD-s in the weaner period (8-30 kg) in a dosage of 2 kg per tonne.

There was no significant effect on the production value when 1 kg Feed ADD-s was added per tonne finisher feed even though the pigs had previously been given feed containing Feed ADD-s (2 kg per tonne). This corresponds with the result of previous trial in which the pigs were given Feed ADD-s in the finisher feed only, and had thus not been given Feed ADD-s from weaning and until transfer to the finisher unit.

Overall, the trial showed no significant difference in the production value between the control group and the trial group in which Feed ADD-s had been added in the selected dosage. It can therefore not be recommended to add Feed ADD-s to finisher feed.
