Impact of orange essential oil on enteric methane emissions of heifers fed bermudagrass hay

Abstract: In this study, the effects of orange essential oil (OEO) on the rumen fermentation, nutrient utilization, and methane (CH4) emissions of beef heifers fed a diet of bermudagrass (Cynodon dactylon) were examined. In addition, in vitro and in situ experiments were conducted. The in vitro experiment consisted of three treatments: control (CTL, no OEO), OEO1 (0.25% OEO), and OEO2 (0.5% OEO). The forage to concentrate ratio was 70:30 (dry matter [DM] basis) in all treatments. No changes in pH, proportions of volatil… Show more

“…Conversely, adding EO doses of clove, mint, and cinnamon of up to 300 ppm showed increased rumen organic matter digestibility in vitro (Rofiq et al, 2021). In addition, EO have a stronger toxic effect than condensed tannin on rumen methanogens (Cieslak et al, 2013), 0.50% orange EO (78.84% D-Limonene) contributed to a 12% reduction in ruminant methane production (Jiménez-Ocampo et al, 2022).…”

“…La producción ganadera genera 37 % de las emisiones mundiales de gases de efecto invernadero (GEI) y se espera aumente a 40 % para 2050; de estos GEI, 80.7 % procede de la fermentación entérica de los rumiantes (1,2) . Los principales GEI producidos por rumiantes son metano (CH4) entérico y en estiércol, dióxido de carbono (CO2) y óxido nitroso (N2O) (3) .…”

“…Los principales GEI producidos por rumiantes son metano (CH4) entérico y en estiércol, dióxido de carbono (CO2) y óxido nitroso (N2O) (3) . El CH4 es un GEI que contribuye a la formación de ozono troposférico; además, tiene una vida corta (9 a 12 años), pero es 25 veces más nocivo que el CO2, por lo que su reducción ayuda a mitigar los efectos adversos del cambio climático (1,2) . Las estrategias de mitigación de GEI se encausan a no afectar el rendimiento animal, reducir el impacto ambiental, mejorar la productividad y rentabilidad de los sistemas de producción (1) .…”
