In vitro rumen fermentation and methane production as affected by rambutan peel powder

摘要

ABSTRACT The current study was aimed to determine the effect of rambutan peel powder (RPP) supplementation on in vitro gas production, rumen fermentation characteristics and methane production. The experimental design was a completely randomized design and the dietary treatments were different levels of RPP supplementation at 0, 4, 8, 12, 16 and 20?￠????mg/0.5?￠????g DM. Under this investigation, RPP supplementation did not affect gas production kinetics and in vitro digestibility ( p ?￠????>?￠????.05). The concentration of NH 3 -N decreased linearly with the increasing levels of RPP supplementation ( p ?￠????
