Pengaruh Molases Pada Amoniasi Jerami Padi Menggunakan Urea Terhadap Kecernaan Bahan Kering dan Bahan Organik In Vitro
ABSTRACT: Aimed of this
research was to find out the optimal level of molasses addition to improve
quality, dry matter and organic matter digestibility of rice straw ammonization
process. Materials used were rumen fluid of fistula cattle, grind of rice
straw, water, urea and molasses. Research designed used Completely Randomized
Design (CRD). As treatments were R0: rice straw 1000 g dry matter + 500 g water
+ 50 g urea + 0 percent of molasses, R1: R0 + 15 percent of molasses, R2: R0 +
30 percent of molasses. Urea and molasses dissolved in water and then entered
into pollybag. All pollybag observe and let for 15 days, each treatment
replicated 6 times. Variable measured were dry matter digestibility and organic
matter digestibility. Research result showed that ammonization product of NH3,
Acidity Level and crude fiber having decreased while crude protein content
increased. Variance analysis indicated that treatments had significant effect
(P<0.05) on dry matter and organic matter digestibility. Orthogonal
polynomial test indicated that level of molasses increase (P<0.05) of dry matter
and organic matter digestibility linearly. It can be concluded that addition up
to 30 percent in ammoniating of rice straw using urea can improve quality of
ammonization and increasing dry matter and organic matter digestibility.
