POTENSI DAN PRODUKTIVITAS HABITAT PAKAN BANTENG (Bos javanicus d’Alton 1832) DI PADANG PERUMPUTAN PRINGTALI DAN KEBUN PANTAI BANDEALIT TAMAN NASIONAL MERU BETIRI JAWA TIMUR

Abstract

The aim of this research is to analyze productivity of feeding habitat national park grazing area and planted area as an bulls feed. The research was conducted in 2009 to 2010 in Pringtali grazing area, Meru Betiri National Park and Kebun Pantai Bandealit Plantation. To collect data on feed vegetation, 20 units of square plot model of 1 m x 1 m, were used randomly and systematically, with distance among plots was 25 m and interval line 50 m. The first plot was randomly and the other plot were selected systematically. The result showed that the carrying capacity of the Pringtali grazing area for the female bulls during the rain season was 29 individuals and 10 individuals during the dry season. Carrying capacity of Bandealit Plantation area for female bulls was 222 individuals on rain season and 110 individuals on dry season. Carrying capacity for the male bulls only half from the female bulls. According to palatability rate of feeds, it ranked as Hierochloe horsfieldii (0.93), Andropogon pertutus (0.92), A. aciculatus (0.86), and Paspalum conjugatum (0.83). Nutrient content of the feed was protein content which consist of i.e 16.21% for A. pertutus (16.21%), H. horsfieldii (9.98), P. montanum (9.65%), A. aciculatus (9.36%), and P. conjugatum (9.31%).
