In August 2004 two juvenile Hyacinth Macaws (Anodorhynchus hyacinthus) arrived at Temaikèn Wild Animal Park. Their feathers were in very bad condition and they weighed 1,230 g on average. At the very beginning, a diet with a great variety of ingredients was given. Two months later, during a first 5-day period leftovers were measured. At that moment the animals weighed 1,305 g on average. Once it was identified which ingredients were preferred, during a second 14-day period the animals were offered a new high calorie diet in order to improve their weight. After that, a maintenance diet was given twice a day and leftovers were measured again. The diet consumed during this third 5-day period, was 50% water; 16.86% crude protein on Dry Matter Basis (DMB) and 15.39% crude fat (DMB). At this time animals averaged 1333.55 g. At the end of the trial these birds had increased their feed intake from 9% to 13% of their body weight on an as-fed basis. Their feather colour also progressively improved.
