AB  - This laboratory scale study examined on silo fermentation of Elephant grass (Pennisetum purpuereum) without additive (Control). And with additives of fermented juice of epiphytic lactic acid bacteria (FJLB) and commercial acetic acid (ACE) powder. The subsequent silages and fresh matter were used to determine their in situ rumen degradability. Duplicate of 3.0g milled silages and fresh matter were weighed in Nylon bags (140 x 75 mm, pore size 20 to 40 um) and incubated in the rumen of dry lactating cow fed on maintenance requirement. Nylon bags were withdrawn at 8, 16, 24, 48 and 72 hours after insertion. The 0-h measurement was obtained by soaking the two bags of each sample in warm water (37 ?C) for 1 h. Nylon bags were then washed with cold water for 20 min in a washing machine and dried for 48 h at 60?C. To estimate the rate and extent of DM and NDF degradability and their degradation characteristics data were fitted to the exponential equation of P = a+b (1-e-ct). The results in this study revealed that FJLB treatment increased (P<0.0) lactate concentration and decreased (P<0.0) losses of nutrients in silages compared to Control and ACE treatments. Similarly, the digestibility of DM and NDF were higher (P<0.05) in the FJLB silage than in the Control or ACE silages. The rate at which (b) was degraded was considerably higher for the FJLB silage [(c) = 0.091 for DM and (c) = 0.34 for NDF] than for the Control [(c) = 0.06 for DM and (c) = 0.28 for NDF] and the ACE silage [(c) = 0.08 for DM and (c) = 0.31 for NDF]. Similarly, the total or cumulative rate (a+b) of DM (65.91%) and NDF (53.78%) digestibility was higher (P<0.05) in the FJLB silage, but that for ACE and Control treatments appeared similar. The additive of ACE at ensiling did not improve the fermentation of Elephant grass and its in situ rumen degradability of silage. More research is needed to evaluate the type and number of the of epiphytic LAB in the forage extract before incubation and in the FJLB after incubation with a view to identify their effectiveness during ensiling and in vivo digestibility of tropical crops silage.
