The study aims to evaluate the effect of aqueous and methanolic extracts of three herbs, namely, neem (Azadirachta indica), drumstick (Moringa oleifera) and scent (Ocimum gratissimum), and three spices garlic (Allium sativum), ginger (Zingiber officinale) and onion leaflets (Allium cepa) on ruminal methane production and fermentation characteristics. The feed samples (200 mg substrates plus extracts of the selected herbs and spices) were incubated with rumen liquor taken from three mature West African dwarf ewes at 3, 6, 9, 12, 15, 18, 21 and 24 h. The results show that extracts of the selected herbs and spices increased the gas produced, from the insoluble fraction, degradability rate, volume of gas produced at time and time of most rapid change in gas produced.
