Trial report 341: Commercial products in feed for finishers

Test of Salocin, Sangrovit, ToyoCerin and Acid Lac for finishers.


Four commercial products for finishers were tested. The products were compared with a control mix with no addition of antibiotic growth promoter. The trial included the following treatments:

  • Control feed without growth promoter
  • Salocin 25 ppm, from Hoechst Roussel Vet
  • Sangrovit 30 ppm, from Hoechst Roussel Vet
  • Sangrovit 50 ppm, from Hoechst Roussel Vet
  • ToyoCerin 20 ppm, from LOHMANN ANIMAL HEALTH GmbH & Co. KG
  • Acid Lac 0.3 per cent, from KEMIN

The trial was carried out in cooperation with the companies concerned, which also supplied the products tested. The companies analysed the feed mixes for their own products. The products were tested on finishers approximately weighing between 30 and 100 kg in one herd. Each treatment included 24 repeats, totalling 81 pigs per group.

The chemical analysis of the feed in general showed good concordance with the calculated nutritional content. Though, the analysed content of lysine was lower than calculated in the feed containing Sangrovit, 50 ppm, at one delivery. The company analyses of their own products showed an acceptable content in relation to the expected content.

The production value of the individual mixes has been calculated on the basis of production results and is stated as gross margin per pen place per year at the same price for all mixes.

The production value of the feed mix with Sangrovit, 30 ppm, was significantly higher than the production value of the control mix without growth promoter. No significant difference showed between the control group and the experimental groups with 50 ppm of Sangrovit, Salocin, ToyoCerin or Acid Lac. However, the production value tended to increase when Salocin was added to the feed mix.
