Artigo de Periódico Acesso aberto (Open Access) Composição bromatológica e cinética da fermentação ruminal de rações contendo resíduos de babaçu(Universidade Federal do Pará, 2014-03) SOUSA, Luciano Fernandes; MACEDO JUNIOR, Gilberto de Lima; SANTOS, Rogério Pereira dos; SILVA, André Guimarães Maciel e; BORGES, IranThe objective of the experiment was to demonstrate the bromatological composition, and evaluate the fermentation kinetics and effective ruminal degradability in vitro, using the "Hohenheim Gas Test" technique, of babassu mesocarp flour I® and II® (FMBI and FMBII) and of feeds at different levels of inclusion. Two trials were carried out: one of pure byproducts and corn, and another of feeds with inclusions of FMBI and FMBII in the following proportions: 0, 7.5, 15.0 and 22.5% of the total dry matter. The experimental design was of randomized blocks, with six blocks in the first trial and five in the second. Measurement times for the gases produced were 3, 6, 9, 12, 24, 48, 72 and 96 hours. The FMBI and FMBII flours showed different bromatological composition for the fibre components (FDN, FDA and Lignin). The FMBI and FMBII flours also showed patterns for fermentation kinetics inferior to the fermentation patterns of corn grain. Increasing the ratio of FMBI and FMBII in the feed reduces gas production for time of incubation. In view of the above, it can be said that mesocarp flours I and II, despite being sources of starch, did not present ruminal fermentation similar to corn grain, the standard source of starch.Artigo de Periódico Acesso aberto (Open Access) Do avortado ao comprado: práticas alimentares e a segurança alimentar da comunidade quilombola do baixo Acaraqui, Abaetetuba, Pará(Universidade Federal do Pará, 2016-04) NASCIMENTO, Elcio Costa do; GUERRA, Gutemberg Armando DinizThis research presents the analysis of different strategies of Food and Nutritional Security (SAN) developed by the families of the Quilombola Community of baixo Acaraqui, Abaetetuba, Pará. The community is facing changes in their eating habits due the reduction of natural resources (hunting animals, fish and shrimps), decrease of the area for agricultural production and increase of the commercial value of production. Using a qualitative approach and the following procedures: participant observation, semi-structured interviews, photographic record, itemized lists and workshops on eating habits, we investigated the community and their production and food practices. We observed a higher specialization of production, decreasing the diversity of local production and of the families’ self-sufficiency; increasing in the importance of extraction of açaí as an income generator; substitution of natural products (natural juices, teas) for industrial products (coffee, soda); increase in purchasing power, stimulated both by market trades and the social benefits received (bolsa família, pension and seguro defeso). This reality has significantly influenced the production practices and eating habits of the local families, interfering with production decisions and food acquisition, making families dependent on trade and income generation in order to ensure the SAN of the quilombola families.
