The experiment was conducted for two years (2017-2018 and 2018-2019) in warm season perennial pastures and cool season annual pastures grazed by beef steers.  Three pesticide-free ICLS treatments - livestock-forestry (LF); crop-livestock (CL), and crop-livestock-forestry (CLF) - plus, a livestock control pesticide-free system (L) were conducted in randomized complete block design, with three replicates per treatment. © 2023 Elsevier Ltd  aAnimal production  aEnteric methane emissions  aEucalyptus  aGreenhouse gases  aMixed swards  aSteers1 aDE FACCIO CARVALHO, P.
