In the Amazon rainforest, countless plants have bioactive compounds, which can potentially be used as modulators of ruminal fermentation. Despite the importance, few studies have been developed to evaluate the use of extracts from Amazonian plants as natural food additives in ruminant nutrition. Thus, the objective is to present a brief overview of the scientific data in the literature on the effects of the use of extracts of açaí, copaíba, sage-do-marajó, peach palm and bacuri in ruminal fermentation and their potential for use in the diet of ruminants. Açaí (Euterpe oleracea Mart.) has high concentrations of flavonoids, compounds with potent antimicrobial action. Studies with açaí oil supplementation have shown modulatory effects on rumen fermentation and milk production in sheep and cows. Copaiba (Copaifera spp.) oleoresin, marajó sage oil (Hyptis crenata Pohl ex Benth) and bacuri (Platonia insignis Mart.) antimicrobial action, capable of reducing the total gas production in the rumen environment in vitro. The peach palm, fruit of the peach palm (Bactris gasipaes Kunth.), has high concentrations of carotenoids, with an in vitro antimicrobial effect against some bacterial strains. The findings of this review demonstrate the potential of Amazonian extracts in maximizing animal production, due to the possible effects on the modulation of ruminal fermentation, being encouraged to carry out additional studies aiming at a greater exploration of them. Although, currently, there are no studies associated with the effects of açaí, sage, peach palm and bacuri on rumen fermentation, it is assumed that, due to their phytochemical composition, they could have a similar effect to ionophores.
