Abstrak

Bawean deer (Axis kuhlii) is endemic species of Bawean Island whose had a critically endangered status. This study aims to determine the feeding preferences of Bawean deer in the ex-situ conservation area ??Bali Zoo Park. This research was conducted from 6 January to 20 March 2020. Cafeteria feeding method was used to determine feeding preferences and continued with nutritional content test, namely crude protein (%), energy (kcal/g), kalsium (%) and phosphorus (%). Feeding preference was determined based on the Ivlev selection index. The feeding preference from the selection index (IS) showed local grass and sweet potato (Ipomoea batatas) was the preferred category, wheat bran (Pollard) was the proportional, elephant grass (Pennisetum purpureum) and carrots (Daucus carota) were the less preferred category. The nutritional content of Bawean deer had met their needs, in which crude protein ranges from 3.89 to 17.30%, energy ranges from 2.8585 to 3.6253 kcal/g, calcium ranges from 0.13 to 0.70% and phosphorus ranges from 0.10 to 0.84%.
