RJ Hughes and G Brooke (2005) APSS 17, 35-38 In contrast, (to wheat and barley) sorghum is generally regarded as a relative consistent source of energy. However, this may not always be the case, as anecdotal evidence from the field suggests that some commercial flocks respond poorly to sorghum-based diets diets

Sorghum-based broiler diets are not very responsive to feed enzymes Phytase AND Xylanase Sorghum: A maligned feed grain for chicken-meat production Pellet quality is an issue (high starch gelatinisation temperatures) Broiler chicks on sorghum-based diets often perform better than the perception But sorghum has an Achilles heel and that is relatively poor starch/energy utilisation Stigma of condensed tannin persists
