Feeding and management procedures
All the experimental birds were housed in a
well-ventilated shed in deep litter pens under uniform
managerial conditions. The reference and test concentrate
mixtures and clean drinking water was supplied
to the birds ad libitum throughout the study period to
meet the nutrient as per [12]. The body weights of all
the birds were recorded weekly in the morning, before
feeding and watering. The amount of feed offered and
residue left after 24 h was measured to find out feed
intake of feed. Feed conversion ratio (FCR) was calculated
by dividing the feed intake by weight gain.
Vaccination and other routine poultry management
practices were carried out neatly.
