Peruntukan Aktiviti Harian Dan Kesan Aktiviti Pengkayaan Terhadap Cimpanzi (Pan troglodytes) Di dalam Kurungan

A study on daily diurnal behaviour of several chimpanzees (Pan troglodytes) was conducted in Zoo Negara. This study was aimed to investigate the diurnal behavioural activities of captive chimpanzees and the effects of enrichment towards their behaviours. Focal sampling with continuous recording was employed. The observations involved 32 days and were conducted from 0900 to 1700 with an hour break, 16 days each for non-enrichment and enrichment observations respectively. Non-enrichment phase was carried in 80 hr and 45 min, while the enrichment phase was conducted in 86 hr 15 min. Results showed that the captive chimpanzees spent more time for resting (45.2%) and observing their surroundings (16.81%), locomotion activities (11.33%), eating (8.38%), grooming (5.27%), foraging (4.81%), sleeping (3.40%), aggressive behaviour (0.38%) as well as other non-define behaviour such as stereotypic behaviour (0.28%) and sexual behaviour (0.14%). The enrichment caused significant changed only to foraging (p 0.001), nest-building (p 0.05) and observing behaviours (p 0.05).
