Abstract

This study aims to obtain the chemical composition, RDP-RUP content and digestibility of tropical legumes from two different regions using the in-vitro method. The legumes used included: A.hypogea, A.pintoi, C.calothyrsus, C.mucunoides, G.sepium, I.zollingeriana, L.leucocephala, M.oleifera and S.grandiflora. The chemical composition of feed ingredients was determined using proximate and van soest analysis. Dry Matter Digestibility (DMD) and Organic Matter Digestibility (OMD) were measured using the in vitro Tiley and Terry method. The research design used was a randomized block design with areas (Luak and dramaga) as treatment then repeated three times. Research data were analyzed using Analysis of Variance (ANOVA) with SPSS software version 25. The results obtained from this study were not significant differences (p>0.05) between treatments for each parameters observed. I.zoliingeriana was the legume with highest CP (30.40%) content among all the legumes observed. DMD ranged from 58.03% (A.pintoi) – 72.68% (I.zollingeriana). The highest RDP content was found in I.zollingeiana (71.28%). The highest RUP content was found in C. mucunoides (46.94%). The conclusion from this study is that tropical legumes of the same type but grown in areas with different environmental conditions tend to have almost the same quality. The database of feed nutrient content is very useful in formulating livestock rations. A good ration formulation is based on the ratio of RDP and RUP so that the needs of rumen microbes and host livestock are met. This research is highly useful to help formulate ruminant livestock rations based on the ratio of RDP and RUP, due to limited information from previous studies.
