Abstract Tucumã oil is sourced from the fruit pulp of the tucumã tree and contains high concentrations of unsaturated fatty acids and carotenoids. Due to these properties it may have the potential to decrease enteric methane (CH4) from ruminants when included in the diet. The objective of this study was to determine the effect of oil mechanically extracted from the fruit pulp of tucumã on fermentation characteristics, CH4 production and the microbial community using the rumen stimulation technique. Treatments consisted of a control diet (forage:concentrate; 70:30), and tucumã oil included at 0.5 or 1.0% (v/v). Addition of tucumã oil linearly decreased (P < 0.01) dry matter disappearance. Total gas (mL/d) and carbon dioxide (CO2) production (mL/d, mL/g DM) were unaffected (P ≥ 0.36) to increasing addition of tucumã oil where 0.5% (v/v) of Tucumã oil numerically increased both variables. Acetate and butyrate percentages of total VFA were linearly decreased (P ≤ 0.01) and propionate and valerate percentages of total VFA were linearly increased (P < 0.01) by increasing concentrations of tucumã oil added to the substrate. The ratio of acetate to propionate was linearly decreased (P < 0.01) with increasing concentration of tucumã oil. Methane production (mL/d) was linearly decreased (P = 0.04) with increasing addition of tucumã oil to the substrate. Tucumã oil reduced the bacterial richness and diversity when included at 1.0% (v/v) in both solid- and liquid- associated microbes. The abundance of the genera Fibrobacter and Rikenellaceae RC9 gut group were decreased and Pyramidobacter, Megasphaera, Anaerovibrio, and Selenomonas were enriched by the addition of 1.0% tucumã oil. In conclusion, tucumã oil resulted in the favorable shift in fermentation products away from acetate toward propionate, decreasing the production of CH4 when tucumã oil was included at 1.0% (v/v), however, substrate digestibility was also inhibited. The rumen microbiota was also altered by the addition of tucumã oil.

A avaliação da qualidade fisiológica de sementes é um aspecto importante para o controle das plantas daninhas. Objetivou-se verificar a viabilidade de sementes de Euphorbia heterophylla resistentes e suscetíveis a herbicidas, após serem armazenadas durante 14 meses, por meio da aplicação dos testes de germinação e tetrazólio. Foi analisada a germinação na ausência e presença de luz, em temperatura constante (25 °C). Para o teste de tetrazólio, as sementes foram selecionadas longitudinal-diagonalmente, colocadas em placas de Petri contendo solução de tetrazólio a 1')10, envoltas em papel-alumínio e mantidas a 30 °C, no escuro e em estufa, por 18 horas. Não foram observadas diferenças significativas entre os biótipos resistentes e suscetíveis de E. heterophylla em ambos os testes. As sementes mantiveram-se viáveis durante o período de armazenamento. As médias de viabilidade das sementes no teste de tetrazólio foram superiores àquelas obtidas nos testes de germinação, sugerindo que, apesar da viabilidade, as sementes de E. heterophylla apresentam dormência quando armazenadas por 14 meses. |
