Summary

Forsøgsdiæterne viste ingen signifikante forskelle i forhold til kontrol diæten mht.:
Specifik vækstrate, SGR ≈ 1,8 %/dag
Foderkvotient, FK ≈ 0,8 (kg foder/kg tilvækst)
Kun mindre variationer i fordøjeligheden af protein og fedt
Men i diæter med højst inklusion af planteprotein:
Signifikante forskelle i fordøjelighed af kulhydrater og fosfor (P) i f.h.t. til kontroldiæten
Højere udskillelse af N. Kan skyldes aminosyre ubalance og afbrænding af aminosyrer
Begrænset P-tilgængelighed (fytin-bundet)

Summary translation

The experimental diets did not show significant differences in relation to the control diet as:
Specific growth rate, SGR ≈ 1,8 %/day
Feed quotiont, FQ ≈ 0,8 (kg feed/kg gain)
However, for experimental diets with highest inclusion of plant protein:
Significant differences in digestibility of carbohydrate and phosphrus (P) in comparison to the control diet.
Higher discharge of N.
Limited P-availability (phytic bound)
