a result, at moderate tannin dose, methane decreased
more than VFA. The in vivo trial was conducted to
investigate the effect of TRP on different ruminal
microbial populations. To this end, 8 rumen-cannulated
sheep from 2 breeds (Texel and Blackbelly)
were used in two 4 × 4 Latin square designs. Diets
were fed ad libitum and were composed of the same
feeds used for the in vitro trial: control plant alone
or combined with pellets made from TRP leaves at
44% of the diet DM. Compared to TRP, concentration
of Ruminococcus flavefaciens was greater for
the control diet and concentration of Ruminococcus
albus was least for the control diet. The methanogen
population was greater for Texel than for Blackbelly.
By contrast, TRP-containing diets did not affect protozoa
or Fibrobacter succinogenes numbers. Hence,
TRP showed potential for mitigating methane production
by ruminants. These findings suggest that
TRP fed as pellets could be used to decrease methane
production.
