Sewage‐grown algae as a source of pigments for broilers

Abstract

1.	Relative utilisations of xanthophylls in young broilers from diets containing meals prepared from the algae Chlorella and Micractinium and alfalfa meal were determined.
2.	Relative utilisation was evaluated from plasma and toe‐web xanthophyll contents, and by visual scoring.
3.	The results showed poorer xanthophyll utilisation from algae‐containing diets than from alfalfa meal, but algae meals can be used effectively as pigment sources in poultry diets.
