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.

Foram estudados os compostos ESALQ PB4 e PB5, de milho visando estimar parametros geneticos relativos aos caracteres producao em peso de espigas, altura da planta e espiga, numero de ramificacoes do pendao e numero de dias para florescimento, avaliar potencial das populacoes para melhoramento intrapopulacional, fazendo-se as comparacoes cabiveis. Utilizou-se delineamento experimental em latice triplo 7 x 7, testando progenies de meios irmaos, sendo sete experimentos relativos ao composto ESALQ PB4 e cinco ESALQ PB5. O plantio foi feito no campo experimental da Escola Superior de Agricultura "Luiz de Queiroz", Piracicaba, no periodo agricola 1984/85. Como testemunha foi utilizado hibrido comercial Cargill 511. Resultados permitem concluir que: a selecao para a producao deve ser conduzida entre progenies, para altura da planta e espiga, feita dentro das progenies; valores da resposta correlacionada indicam que selecao exclusiva para producao, entre progenies, nao afeta de maneira sensivel a media para demais caracteres nos ciclos seguintes; ausencia de indicacao alta correlacao entre numero de ramificacoes do pendao e peso de espigas sugere que a selecao para o numero de ramificacoes do pendao nao se faz necessaria; ambos compostos apresentaram perspectivas de melhoramento muito promissoras, tanto em relacao a producao, como para altura da planta, alura da espiga e precocidade de florescimento; ESALQ PB5 apresentou maior potencial para melhoramento a medio prazo. |
