PIZZANI, Pablo et al. Phytochemical and nutritional composition of pijiguao (Bactris gassipaes Kunth en H.B.K) meal. Zootecnia Trop. [online]. 2008, vol.26, n.3, pp.235-238. ISSN 0798-7269.

To evaluate the phytochemical and nutritional composition of the whole meal of Pijuguao (Bactris gassipaes) fruits (WMP), it was determined by phytochemistry screening the presence of fourteen secondary total metabolites: total phenols, flavonoids, tannins to precipitate the proteins, condensed tannins, steroids, quinons, cumarins, non-proteins amino acids, alkaloids, saponins, triterpens and proanthocyanidins, catechins, reducing sugars and mucilage, NDF, ADF, PC, macro and micro minerals, and ash. The phytochemical study indicated the presence of non-protein amino acids, triterpens, reducing sugars and catechins; the rest of secondary metabolites did not showed positive reaction. The various components of the mineral and chemical analysis gave a crude protein of: 6.58%, 12.58% fat, Ash: 1.98%, Ca 0.08%, P 0.11%, Mg 0.05%, K 0.39%, and 20, 22, 4 y 3 ppm para Fe, Zn, Cu y Mn, respectively. The estimated metabolizable energy content of the WMP was 12.41 MJ / kg. The fiber content, expressed as NDF and ADF were 21.16 and 10.44 %, respectively. The values of degradability in vitro dry matter was 80%.Accordingly, we conclude that the WMP represents an alternative energy source to feed ruminants because with low secondary metabolites contents and high in vitro degradability values.
