Judul: Preferensi Pakan Tambahan Limbah Sayuran Pada Rusa Timor (Rusa Timorensis) di Penangkaran dan Pengaruhnya terhadap Perilaku Makan
Abstrak: Feed is the most important factors to determine the success of a captivity. Additional for age can be provided to deer to solve the limitation of grass availability as the primary feed for timor deer. Additional vegetables waste have advantage because the price is relatively cheap. Considering the problem, this research was conducted in the aim to identify kind of vegetable waste which is most preferred by the timor deer and any typical behavior which is possible showed by deer possibility as a negative impact of additional vegetables waste as feed. Research was held in captivity deer of Dramaga Research Forest in June until July 2012. Four individual timor deers (2 adult males and 2 adult females) were observed and four type of feed (mixed grass, corn skin, cabbage waste and chicory waste) were provided as additional for ages. There were two observation techniques used, they were supplementary feed preference and eating behavior. In feed preference, three types of vegetable waste and mixed grass as primary feed were given simultanously to deer . Two kilograms of each feed type were given daily to each. While in eat behavior, for age were given based on treatment. Every treatment consisting of 3 kg mixed grass and 3 kg vegetable for each pair deer. The data of feed preference were analysed by Index Nue. The result showed that skin of corn was preferred by both male and female deer with w value sequently 1,32 and 1,36. Afterward, vegetable waste feed affected eating behavior of the timor deer. The period of eating relatively shorter on the type of supplementary feed which was most preferred by both male and female timor deer, and longer on the type of supplementary feed which was not preferred. Chi-Square test showed that there was a significant difference, it showed the value of count χ² (161,387) was larger than the value of table χ² (7,378). Moreover, typical behavior as a negative affect from leftover cabbage as supplementary feed was found. It happened to male timor deer which fell asleep and drooling while sleeping. This was because cabbage contained a gas that could increase the gas in the stomach, so the timor deer's energy focused on the digestive system and caused male timor deer asleep.

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.
