The aim of this study was to assess the growth performance, forage intake and methane (CH4) emissions by beef cattle grazing under different spatiotemporal integrated crop-livestock systems (ICLSs). 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
