The Effects of Aquilaria agallocha Roxb. Volatile Oil on In Vitro Ruminal Gas Production, Methane Emission, Volatile Fatty Acide Amounts and Protozoa Counts of Total Mixed Ration of Dairy Cattle

Methane (CH4), a major greenhouse gas produced during ruminal fermentation, has significant ratio in both the economic and ecological impact of global climate change. Literature reports have been published, which suggest that dietary supplementation with plant volatile oils reduces methane emissions ruminant production. This vitro study was aimed at investigating effects agarwood (Aquilaria agallocha Roxb.) oil on production, emission, organic acids protozoa counts total mixed ration (TMR) dairy cattle. Component analyses were performed for oil. The oil, added to fluid levels 5, 10 15 µL/0.2 g dry matter (DM) (Groups A0, A5, A10 A15), digestion determined based In conclusion, it ascertained addition µL Aquilaria Roxb. positively affected production parameters cattle, showed an antimethanogenic effect.
