Urea in sugarcane-based diets for dairy cows
Santiago, Alberto Magno Ferreira; Campos, José Maurício de Souza; Oliveira, André Soares de; Valadares Filho, Sebastião de CamposWe evaluated the effect of adding four levels (0, 4, 8 and 12 g/kg, as fed) of a mixture (9:1) of urea and ammonium sulfate (UAs) to sugarcane on feed intake and digestibility, productive performance and metabolism of nitrogen compounds of dairy cows. Twelve multiparous Holstein cows (12.6±0.5 kg/d of milk, 225±90 days in milk) were distributed in three 4 × 4 Latin squares, receiving diets with the same amount ...
Plant growth promoting bacteria associated with langsdorffia hypogaea-rhizosphe...
Felestrino, Érica Barbosa; Santiago, Iara Furtado; Freitas, Luana da Silva; Rosa, Luiz Henrique; Ribeiro, Sérvio Pontes; Moreira, Leandro MarcioSoil is a habitat where plant roots and microorganisms interact. In the region of the Brazilian Iron Quadrangle (IQ), studies involving the interaction between microbiota and plants have been neglected. Even more neglected are the studies involving the holoparasite plant Langsdorffia hypogaea Mart. (Balanophoraceae). The geomorphological peculiarities of IQ soil, rich in iron ore, as well as the model of intera...

Santiago, Iara FurtadoApesar das relações ecológicas, evolutiva e do potencial biotecnológico de muitos microrganismos, pouco se conhece da micota presente no continente Antártico. Desta forma, este trabalho teve como objetivo detectar a presença de metabólitos bioativos produzidas por fungos endofíticos associados as angiospermas antárticas Deschampsia antarctica Desv. (Poaceae) e Colobanthus quitensis quitensis (Kunth) Bartl. (Car...
