The utilization of faecal inoculum of cow to investigate The in vitro digestibility of Kumpeh Grass (Hymenachne Amplexicaulis

Abstract

The aim of this study was to reveal the effect of faecal inoculum on the in vitro digestibility of dry matter, organic matter and the gas profile of Kumpeh grass(Hymenachne Amplexicaulis). The design of this research was Completely Randomized Design (5 x 4) with five treatments and four replications. The treatments were rumen liquor inoculum, faecal inoculum (FI), FI added with sugar of 2.5 % (w/v), FI added with sugar of 2.5 % (w/v) and urea of 2.5 % (w/v) and FI added with urea of 2.5 % (w/v) for treatments A, B, C, D and E respectively. Samples of Kumpeh grass were tested by the two steps in vitro technique of Tilley and Terry. Results of this study showed that faecal inoculum significantly (P<0.05) decreased the digestibility of dry matter, organic matter and the gas profile of Kumpeh grass. The use of faecal inoculum (treatment B, C, D and E) had the lower digestibility of dry matter, organic matter than that of the rumen liquor. It might be concluded that the addition of sugar or and urea in the faecal inoculum could not increase yet the digestibility of dry matter, organic matter and gas profile of kumpeh grass.
