Resumen
- Five levels of pH (6.50; 6.25; 6.00; 5.75 and 5.50) were adjusted according to the inclusion of bicarbonate ion in the incubation solution, to simulate fermentation conditions under high concentrate feeding. The pH diminished linearly (P<0,001) with the buffering of the media, and remained constant throughout the 12 h incubation period except for treatments 5,75 and 5,50, whose pH continued decreasing to 5,51 and 5,31 at 12 h, respectively. Gas production decreased linearly with the medium pH (P<0,001) from 2 to 10h, and quadratically at 12 h. The total volume of gas produced after 12 h was correlated to pH at 12 (R2=0,629, P <0,01) and 6 (R2=0,836, P<0,01) h.
