Impact of essential oils on methane emissions, milk yield, and feed efficiency and resulting influence on the carbon footprint of dairy production systems

Abstract: Reducing CO 2 emissions is one of the highest priorities in animal production. Regarding methane reduction, feed additives are of growing importance. As shown in a meta-analysis, the use of the essential oil (EO) blend Agolin Ruminant affects methane production per day (-8.8%), milk yield (+4.1%) and feed e ciency (+4.4%).Building on these results, the present study investigated the effect of varying individual parameters on the carbon footprint of milk. The environmental and operational management system REPR… Show more

“…The use of specific feed mixes (e.g. incorporating essential oil blends) in dairy farming are one strategy for reducing methane emissions, while positively affecting milk yields, that has been supported by literature ( 24 ) . Another strategy for improving the sustainability of farming practices is the use of rotational grazing, which are pasture management practices designed to increase the quality and quantity of forage ( 25 ) .…”

“…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) .…”
