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
