Summary in the original language of the document
Et fodringsforsøg blev udført på Todbøl Dambrug, Møldrup, Denmark. Formålet var at undersøge 2 forsøgsfodertyper under kommersielle forhold på økologiske dambrug. Med de 2 diæter undersøgtes effekten af at reducere inklusionen af fiskekmel fra 59 % til 35 % på vækst og sundhedstilstand hos økologiske regnbueørreder under kommersiel produktion.
Mens kontrol diæten kun indeholdt fiskemel og fiskeolie som protein og oliekilde var fiskemelsandelen reduceret fra 59 til 35 % og erstattet med en matrix af hestebønner, ærter og raps i forholdet 1:1:0.7).
Forsøget viste ingen statistiske forskelle i vækst og foderkonvertering hos fisk fodret med forsøgsdiæten, hvor fiskemelet var delvist erstatet med planteprotein i sammenligning med kontroldiæten.
Summary translation
A feed experiment was carried out at Todbøl Trout Farm, Snedsted, Thy, Denmark. The aim was to investigate two experimental diets under commercial conditions in organic trout farms. The two diets investigated the effect of reducing the inclusion of fish meal from 59 % to 35 % on the growth performance and health conditions of organic trout during commercial production.
The basic diet included only fish meal and fish oil as protein and oil source, respectively. In the experimental diet the inclusion of fish meal was reduced from 59 to 35 % and replaced by a matrix of horse bean, pea and rape (ratio: 1:1:0.7).
The experiment showed no statistical differences in growth and feed conversion in fish fed the experimental diet in which the fishmeal had been partially replaced by organic vegetable protein sources compared to the fishmeal based diet.
