| Abstract | This study aimed to evaluate the effect of cutting intervals of Hemarthria compressa on feed intake, nutrient digestibility, and energy concentration of the grass consumed by Thai indigenous cattle. A 3 ? 4 incomplete Latin Square Design was used. Treatments were 3 cutting intervals (30, 45 and 60 days) of grass fed to the bulls as green forage. Four Thai indigenous bulls were allocated into the experimental treatments. Total collection method was used. Feed intake, apparent nutrient digestibility and energy concentration of grass were subsequently assessed. The result showed that it was a linear decline (p<0.05) in crude protein (CP) and ash contents as cutting intervals increased while there were linearly increased (p<0.05) in dry matter (DM), organic matter, neutral detergent fiber, and acid detergent lignin contents. As grass maturation increase, CP intake was decreased but not for DM intake (79.11-81.90 g/BW0.75/d). There was no significant difference of the digestibility coefficient of any nutrient among cutting intervals except gross energy. Nevertheless, the metabolizable energy concentration of the grass were significantly decreased (linear, p<0.05) in accordance with increasing cutting intervals. In conclusion, harvesting the grass at 30 days of regrowth gave better nutritive values and suitable to use as livestock feed. |
