Effects of levels of tropical rice husk-derived biochar in diet-based high rice straw on in vitro methane production and rumen fermentation

Popis výsledku v původním jazyce

This study was conducted to evaluate effects of biochar levels in diets on in vitro methane emission and rumen fermentation. Biochar, produced from rice husk, pyrolysis at 700 °C, was supplemented in diets at 0, 1, 3, 5, and 7% (dry matter (DM) basis). Total gas, methane production, dry matter (DM) and organic matter (OM) digestibility, pH, and NH3-N concentration were measured at 4, 24, and 48 h after incubation. Results showed that total gas and methane emission of diets with biochar was lower than that of the diet without biochar. Methane production decreased linearly (P < 0.01) with increasing biochar levels. DM and OM digestibility, as well as NH3-N concentration of diets with 1 or 3% biochar, was similar to the diet without biochar. When the dietary biochar level was increased up to 5 or 7% in diets, OM and DM digestibility and NH3-N concentration decreased significantly compared to the diet without biochar (P < 0.01). Our findings implicated that supplementing 3% biochar (DM basis) to the diet is recommended to reduce methane production.
