Food preferences of cockatiel chicks ( Nymphicus hollandicus ) in captivity
ABSTRACT In order to improve the management and maintenance of the quality of life of captive wild birds, this study aimed to assess the food preferences of cockatiel chicks (Nymphicus hollandicus) kept in captivity. Thirty-two cockatiel chicks, three to 12 months of age, were kept in a galvanized, wire-netted vivarium with six ceramic feeders, two for an extruded diet, two for a dry-mashed diet and two for a seed mixture. Both extruded and dry-mashed food are commercial psittacine diets. Three round ceramic pots were used to provide water. The birds were exposed to 12 hours of artificial light (40 W incandescent lamps) during the experimental period of 27 days. The birds were observed by video filming, daily, through an ad libitum observation technique. The food consumption was 3.34±0.42g/bird/day of extruded feed, 1.58±0.44g/bird/day of dry-mashed diet and 3.73±0.10g/bird/day of seed mixture. In conclusion, the cockatiel chicks preferred the seed mixture and the extruded food over the dry-mashed diet
