Tonkean macaques are one of seven endemic macaque species on Sulawesi Island. Feeding management in captivity should pay attention to the quality, palatability, and feeding behavior patterns of animals. The goal of this study was to compare the feeding behavior of two social groups of Tonkean macaques at Schmutzer Primates Center (SPC) and Ragunan Zoo (RZ) with different captive management, which was expected to affect feeding behavior. Ad libitum sampling was used to observe daily behavior and hierarchy, while focal animal sampling was used to observe feeding behavior and feed preference. Data were collected from September 2013 until March 2014 with a total of 495 hours of observations. There were significant differences between the daily behavior of two groups of Tonkean macaques. Resting behavior was dominant in RZ group with non-enrichment feed cage, while feeding behavior was more common in the SPC group with an enrichment feed cage. The SPC group spent most of their feeding time in searching for feed, while choosing, carrying and refusing were greater in the RZ group. Both Tonkean macaque groups showed individual dominance in their feeding behavior. Provisioned feed in both locations had different diversity and preference values. The selection of feed required was based on preference values with attention to Tonkean macaques’ feed in nature. Cage construction, such as the SPC cage, was able to reduce abnormal behavior exhibited by individuals.
Monkey Eating Behavior tonkean (Macaca tonkeana) in Schmutzer Primate Center and Ragunan Zoo, Jakarta. Tonkean monkey is one of seven species of monkeys endemic in Sulawesi. The management of feed in captivity must pay attention to the quality, palatabilitas, and eating behavior patterns of animals. The purpose of this study was to compare the feeding behavior of the two social groups of monkeys tonkean in Schmutzer Primate Center (SPC) and the Ragunan Zoo (RZ) with different breeding management, which allegedly could affect eating behavior. Ad libitum sampling used to observe the daily behavior and hierarchy, while focal animal sampling used to observe the feeding behavior and feeding preferences. Data were collected from September 2013 through March 2014 with total 495 hours of observation. There is a real difference to the daily behavior between the two groups of monkeys tonkean. Behavior rest dominant in the group RZ with cages without enrichment feed, while eating behavior more common in group SPC in cages with food enrichment. SPC group spent the largest meal is to search feed, while selecting, lead and push higher in the group RZ. Both groups of monkeys tonkean showed the dominance of individuals on their eating behavior. Food was given in both locations have the diversity and value of different preferences. Selection of feed needs to be done based on the value of the preference, having regard to feed monkeys in the wild tonkean. construction of the cage, like enclosure SPC, able to reduce abnormal behavior exhibited by individuals.
