Potential Utilization of Tree Legume Leaves and Straw as Local Feed Resources of Large Ruminant in the Tropic

The objectives of this study were to determine the ability of ongole grade cattle (OGC) and Buffaloes (B) in intake and digestibility of Calliandra calothyrsus (CC), Gliricidia sp. (G) Corn stover (CS). The study used 5 females (OGC) and 5 females (B). This research was carried out in two periods, namely the adaptation period 14 days and the collection period 15 days. The variables observed were voluntary intake of neutral detergent fiber (VINDF), digestibility of neutral detergent fiber (DNDF), digestibility of acid detergent fiber (DADF), digestibility of crude protein (DCP). Treatment is designed in 2 x 3 factorial. The results showed that (OGC) and (B) had different abilities to intake NDF (g/kg BW 0.75day) (1.72 vs 1.86). (B) have the ability to intake NDF (CS) higher than OGC (4.13 vs 3.80) while (CC) and G are the same (0.80 vs 1.27 and (0.57 vs 0.57). (B) have the ability to intake NDF (CS) higher than OGC (4.13 vs 3.80) while (CC) and (G) are the same (0.8 vs 1.27 and 0.57 vs 0.57). (OGC) and (B) are the same in (DCP), NDF and ADF (%). (DNDF) and (DADF) was highest at (CS) (68.53; 63.57) then (G) (43.87; 42.50) and lowest at (CC) (40.48; 33.19). The highest (DCP) was at (G) (66.04) followed by (CC) (47.47) and (CS) (944.10). In conclusion, intake NDF (CS) was higher than (CC) and (G). (DNDF) and (DADF) (CS) was higher than (G) and (CC). Intake of NDF (CS) in (B) is higher than (OGC).
