SELEKSI JENIS TUMBUHAN PAKAN DAN KANDUNGAN NUTRIEN JENIS TUMBUHAN YANG DIMAKAN SAPI BALI (Bos sondaicus) LEPAS SAPIH DI DAERAH BUKIT BADUNG SELATAN, KABUPATEN BADUNG, BALI

Abstract

This study was conducted to determine the plants species and nutrient content of plant
species selected by weaning of bali cattle in South Badung Hill, Badung regency, Bali. Study
was conducted in three Grazing unit Bali cattle are Sawangan, Kutuh and Pecatu. In
December 2013 to February 2014. Determination of the composition of plant species in the
habitat (n?) is determined by the square method. Determination of plants composition in diet
(r?) determined by utilization methods. This method is based on the percentage bite mark of
plants species in plot sampling. Nutrient content was analyzed crude protein, energy, calcium
and phosphorus. Crude protein determination with a Semi-micro Kjeldahl technique and
energy content by Bomb Calorimeter. Determination of mineral content of calcium (Ca) and
Phosphorus (P) by using Atomic Absorption Spectrophotometer (ASS). Tests carried out in
the Laboratory of Nutrition and Forage Analytical Chemistry, University of Udayana. The

results study showed 32 species of plants available in the habitat, there are nine species of
plants that are selected by weaning bali cattle, that are Desmodium heterofilum, Pleura
interupta, Polygala glomerata, Cyperus rotundus, Desmodium triflorum, Dactyloctenium
aegyptium, Portulaca sp. Polygala chinensis, and Panicum eruciforme. Nutrient content of
plant species eaten a protein ranged from 11.25% - 17.14%, GE 3.10 kcal / g - 4.11 kcal / g,
Ca 0.33% - 1.86%, and 0.026% P - 0.24%.
