Digestibility trial: At the end of the feeding trial, four (4)
birds per replicate were randomly selected and
transferred to metabolic cages for faecal collection and
determination of apparent nutrient digestibility. The birds
were allowed to adjust to the cages for three days. The
digestibility trial lasted 4 days. The total collection
procedure was employed for the faecal collection.
Polythene sheet spread underneath the cages was
used for the faecal collection. Feathers and other dirties
were hand picked and discarded from the faeces before
weighing.
