Judul: Perilaku dan Aspek Pakan Rusa Timor (Rusa timorensis Blainville 1822) Remaja Pada Kandang dan Jenis Pakan yang Berbeda
Abstrak: Efforts to improve the productivity of java deer (Rusa timorensis) can be done through improvements in the feed management and maintenance customized with deer behavior. This research aims to study the aspects of feed and daily behavior of java deer in adolescent age group (12-24 months) in captive breeding of Hutan Penelitian Dramaga, Bogor. In this study, deer were fed selective forage (Coix lacryma-jobi Lour, Pennisetum purpureum Schum, Hierochloe horsfieldii Maxim, and Commelina benghalensis L) and field grass. Result show on individual cages, the highest feed preference value was Pennisetum purpureum Schum and the highest feed palatability value was Hierochloe horsfieldii Maxim. The opposite result occured in the collective cage. On feeding selective forage, the average daily consumption of fresh and dry matter of feed, daily gain and feed efficiency deer were 4.87± 0.51 kg/head/day, 0.73±0.07 kg/head/day, 0.15±0.05 kg/head/day and 22.59%. Averaged digestibility coefficients of feed of java deer was 52.95±6.90% of dry matter, 30.87±26.00% of crude fat, 49.68±2.76%of crude protein, 56.49±6.48% of crude fiber, and 59.21±8.40% of N-free extractive. Daily behavior of java deer in individual cages were dominated by eating, rumination, movement and resting. In conclusion, to increase production that deers is better to be raised on individual cages.

Abstrak: Timor deer (Deer timorensis) which known as deer java is native fauna indonesia which much found in ex-situ. Deer be an attraction object of tourism in captivity. The purpose of this research is identify deer feed that given by visitors in captivity, and identity the whereabouts changes in the behavior patterns of consumption and feed timor deer cause the provision of feed by visitor. The identified feed given by visitors to deer are about 89% convolvulus, 8% carrots, 2% the leaves, 1% wild grasses. Feed which gave great influence in order to meet the basic needs of a deer is convolvulus containing 8,93% protein and carrots containing 19,99% protein. Result of statistic test by used chi-square indicates that no real influence on the behaviour and consumption patterns of deer in captivity, but nominally showed the increase and decrease of presentation. Based on observations, behaviour that increase are food and social, whice breaks, locomotion, and rumination behavior decreased.
