RIRIN RIHATNI. Preference of Additional Feed Vegetables Waste on Timor Deer (Rusa timorensis) in Captivity and Its Effects on Eat Behaviour. Under supervision of ACHMAD MACHMUD THOHARI and YANTO SANTOSA.

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.

Key word : Timor deer (Rusa timorensis), captivity, feed, vegetable waste, eat behavior.
