COELHO, Gabriela de Jesus et al. Perspectives on the use of extracts from Amazonian plants and fruits (açai, copaiba, salva-do-marajo, pupunha and bacuri) as potential modulators of ruminal fermentation: a brief overview. Ces. Med. Vet. Zootec. [online]. 2022, vol.17, n.2, pp.36-62.  Epub 15-Nov-2022. ISSN 1900-9607.  https://doi.org/10.21615/cesmvz.6773.

In the Amazonian Forest, diverse 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 feed additives in ruminant nutrition. Thus, the objective of this study is to present a brief overview of the scientific data in the literature regarding the effects of the use of extracts of açaí, copaíba, sage-do-marajó, peach palm, and bacuri on the ruminal fermentation and their potential for use in the diet of ruminants. Açaí (Euterpe oleracea Mart.) has 16.08 mg/g of dry matter of flavonoids, compounds with potent antimicrobial activity. Studies with açaí oil supplementation have shown modulatory effects on rumen fermentation and milk production in sheep and cows. Additionally, the copaiba oleoresin (Copaifera spp.) and the bacuri (Platonia insignis Mart.) seed butter have 88% and 41% of terpenes, respectively; the phytochemical composition of marajó sage oil (Hyptis crenata Pohl ex Benth) is not completely resolved, but this source is mostly composed of the terpenes, camphor (33.62%), 1,8-cineole (19.76%) and α-pinene (15.24%), which have in vitro antimicrobial effects against different 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, there are no current studies associated with the effects of açaí, sage, peach palm, and bacuri on rumen fermentation, it is inferred that, due to their phytochemical composition, they may have a similar effect to ionophores on ruminant production.
