| dc.description.abstract | An in vitro ruminal gas production study was conducted to assess the effect of yeast
supplementation on rumen fermentation of tanniniferous tropical browse mixtures prepared
by mixing Berchemia discolor with Acacia brevispica, Acacia elatior, Acacia mellifera,
Balanites aegyptiaca, Grewia bicolor or Zizyphus mucronata in a 1: 1 dry weight ratio. The
six browse mixtures were incubated with buffered rumen fluid alone or supplemented with
dried Japanese Sake yeast (JSY) or polyethylene glycol (PEG). Ruminal gas production
characteristics were evaluated using the Gompertz equation. The JSY addition increased
gas production volume (P< 0.05) and numerically increased the maximum gas production
rate constant. Time to reach the maximum gas production rate was shortened by PEG
addition as compared to the JSY and control treatments. It is possible that JSY promoted … | en_US |
