Abstract


The aim of the current work is to evaluate nutrient profile, relative feed value (RFV)
and in vitro true digestibility (IVTD) of 5 tropical legume in Indonesia. Daisy II Incubator
(Ankom Technology Corp, Fairport, NY) was used for IVTD measurement. Arachis hypogea,
Indigofera zollingeriana, Leucaena leucocephala, Gliricidia sepium and Vigna radiata were
evaluated in this experiment. Variables measured were nutrient composition, relative feed
value and in vitro true digestibility. Experimental design of this study was completely
randomized design with six treatments and four replications. The results show that L.
leucocephala contains the highest crude protein content (31.36%). The lowest neutral detergent
fiber (NDF) and acid detergent fiber (ADF) contents were produced by L. leucocephala by
33.16 and 21.43% respectively (P<0.05). L. leucocephala and I. zollingeriana produced the
highest RFV and included in “prime” forage quality value. The highest IVTD was produced by
I. zollingeriana and L. leucocephala by 74.99 and 73.47%, respectively (P<0.05). Based on
fiber profile, RVF and IVTD value, L. leucocephala was the best quality of tropical legume as
forage.
