摘要：Brazilian livestock is of paramount importance to the country's economy. Pastures stand out for their low cost and, when in good condition, meet the nutritional needs of animals. However, the current conditions of Brazilian pastures have been questioned regarding the lack of adequate management and animal rotation, resulting in an increase in degradation and in greenhouse gas (GHG) emission rates. The objective of this work was to approach the use of associative diazotrophic bacteria as a sustainable alternative in animal production and GHG mitigation. Chemical fertilizers, in addition to the high polluting potential, are costly to the producer, making the practice unsatisfactory for the farmer. Thus, the use of diazotrophic bacteria becomes a viable alternative due to their benefits for the soil, plant and atmosphere system, acting as plant growth promoters (PGPB) through solubilization and fixation of nutrients, in addition to the production of growth hormones. The use of these microorganisms brings environmental benefits, as it promotes better conditions for pasture, reducing degradation and GHG emissions. In addition, it presents satisfactory results in terms of forage productivity, economically benefiting the system and helping to reduce the impacts generated by animal production. Considering the constant search for better development conditions and sustainable production alternatives, the use of diazotrophic bacteria in livestock has shown to be efficient even when fertilizers are not used.
