Modificación de la fermentación ruminal in vitro para mitigación de metano mediante la adición de aceites esenciales de plantas y compuestos terpenoides

Essential oils from plants are volatile aromatic compounds, mainly terpenoids, phenylpropanoids; monoterpenes, sesquiterpenes, and alcohols, these present a wide range of antimicrobial antioxidant activity, so the addition essential clove, eucalyptus, mint, rosemary, oregano, cinnamon can modify ruminal fermentation by reducing population bacteria producing methane thus have reduction in production this gas. The objective work was to evaluate different terpenoid compounds improve fatty acids, attenuating generation methane. chemical composition (terpenoids) oils, as well acids (VFAs), were determined gas chromatography. For vitro digestibility, technique used, liquid used. Methane inferred concentration VFAs. It found that all presented each one terpenoids concentrations, reporting highest carvacrol oil clove (303 mg mL-1) oregano (1.20 mL-1); terpinene greater quantity peppermint (4.83 for rosemary oil, linalool higher limonene, eucalyptus (449 (12.42 mL-1). at dose 0.3 176 mL g-1 DM. high (0.6 mL) best since it had better mitigation (716.83 mM/L) without negatively affecting VFAs (acetate, 1892.2; propionic, 526.14; butyric, 24.99 mM/L), like thymol, linalool, limonene doses. is concluded with observed dose.
