Seeds
Afzelia seeds have been shown to contain alkaloids and other antinutritional metabolites (Igwenyi et al., 2014). The slightly detrimental effect of afzelia seeds on poultry has been attributed to the presence of alkaloids and phytates (Ayanwale et al., 2007), but the presence of a water-soluble gum (xyloglucan) that becomes viscous when hydrated could be another explanation, particularly in poultry.
