Effect of Different Levels of Condensed Tannin from NEEM Leaf with Polyethylene Glycol on in Vitro Gas Production
The objectives of this study was to investigate the effect of different levels of condensed tannin from Neem leaf
with polyethylene glycol on in vitro gas production (CTs contained at 2, 4, 6 %DM) with PEG contained at 10, 20 and 30 g.
Effect on in vitro gas productions parameter CT at 6 %DM with PEG at 10g can reduce gas production and reduce methane
production. The results suggested that Neem leaf and PEG contained different concentration of CTs had different effect on
in vitro gas and methane production, however, others factors affected on biological properties of CTs, such as molecular
weight and structure should be further investigated.
