A new view of animal science: challenges and perspectives: Proceedings. Foz do Iguaçu: SBZ, 2017. p. 276.c2017  aThe use of integrated systems had been presented as an option to improve livestock production systems. This study aimed to evaluate beef cattle production systems. The experiment was carried out at Embrapa Agrossilvipastoril, Sinop/MT, from August/2015 to July/2016, follow a randomized complete block design, with four systems and four replications, totaling 16 experimental units (2 ha each). Four production systems were evaluated: livestock (L) ? palisade grass (Brachiaria brizantha cv. Marandu) pastures; livestock-forestry (LF) integration ? palisade grass pastures with triple rows of eucalyptus (Eucalyptus urograndis, H13 clone), spaced 3 m between trees, 3.5 m between rows, and 30 m between ranks and height of 18 m; crop-livestock (CL) integration ? soybean crop (Glycine max L.), succeeded by maize (Zea mays L.) as the second crop snow along with palisade grass, which was used in the first 2 years to create a straw coverge of the soil for the no-till system implemented, and then used as first year pasture; and crop-livestock-forestry (CLF) - first year palisade grass pastures, after two years of crop as describe in CL system, with single rows of eucalyptus, spaced 3 m between trees, 37 m between ranks and height of 18 m.  aEucalyptus  aProduction technology  aSilvopastoral systems  aAgrosilvopastoral systems  aProduction systems1 aSILVA, N.
