Daftar Isi:
- This investigation was conducted to study the influence of protected kapok seed oil supplementation on forage fiber utility. Native grass, kapok seed oil, and sheep rumen fluid were used as experimental material. There were two treatment factors, namely kapok seed supplementation (S) as factor I and protection by saponification as factor II. Factor I consisted of 4 levels, were 0% (S0); 5% (S1); 10% (S2) and 15% (S3), wheareas factor II consisted of 5 levels, were 0% (P0); 25%(P1); 50 % (P2); 75 % (P3) and 100% (P4). The measurement variables included in vitro NDF, DM and OM digestibility, VFA, NH 3 and total protein production. Collected data were statistically analized by analysis of variance with factorial treatment pattern in completely randomized design. The result of this investigation showed that kapok seed oil (KSO) supplementation at 5% without protec-tion, did not influence the fiber utility. The fiber utility decreased, if KSO supplementation was increased up to 10% or more without protection. The decreasing of fiber utility increased with the increasing of KSO spplementation levels. Kapok seed oil protection could improve the utility of fiber, which reflected in increas-ing of in vitro NDF, DM and OM digestibility of native grass were supplemented by 10 and 15% KSO. Supplementation of KSO up to 5% did not influence total protein production. The increasing of KSO supple-mentation up to 10% or more decreased total protein production. The protection of KSO supplementation at that level will improve total protein production, up to the production of control group, supplementation of KSO at 10% level combined with 50; 75 and 100% protection levels. The highest total protein production was found in the combination treatment between supplementation KSO 10% and 75% protection level.
