The invention relates to the technical field of feed additives, in particular to a sustained-release feed additive containing eucalyptus globulus essential oil for rumens of cattle and sheep. The CO2-triggered eucalyptus globulus essential oil sustained-release capsule comprises a CO2-triggered eucalyptus globulus essential oil microcapsule unit, a cobalt acetate sustained-release microsphere unit and a carrier unit. Wherein the microcapsule unit is of a three-layer core-shell structure and can respond to CO2 partial pressure in the rumen gas production peak period to achieve pulse type rapid release of eucalyptus globulus essential oil, and methanogens are accurately inhibited; the sustained-release microsphere unit adopts functionalized polysaccharide composite microspheres to load cobalt acetate, can stably release cobalt element in rumen, and slowly and continuously releases cobalt element in abomasum and intestinal tract after passing the rumen. The two parts are compounded in a physical mode and do not interfere with each other, and space-time precise delivery and function coordination at different parts of the digestive tract are achieved. The method can effectively improve the methane emission reduction efficiency, improve rumen fermentation and improve the nutrient digestibility of the feed.
