Resumo: | The forage conservation as silage is a way to provide good quality forage during grazing scarcity periods, in this way, the objective was to evaluate the effect of pre-wilting and nitrogen fertilization on the fermentation characteristics and nutritive value of white oat silage, in two harvest stages. The experiment was conducted in 2011 at UTFPR, Dois Vizinhos-PR, Brazil. The experimental design was in a randomized blocks with two factorial arrangement and three replicates. The main treatments were six nitrogen doses: 0, 40, 80, 120, 160 and 200 kg ha-1, and secondary the stages of cutting for silage: early flowering with and without pre-wilting, and at blooming without pre-wilting. It was observed that nitrogen fertilization promoted a reduction in pH and mineral content of the silage, reducing fiber content and increasing crude protein content (CP), when made at oat early flowering. The effect of pre-wilting in early flowering inhibits the production of effluents and has higher levels of CP, without any effect on the fermentation and nutritional value. The silage at blooming stage features better standards of fermentation, with lower pH and buffering capacity, but with lower nutritional value. |

O experimento foi conduzido em 2011, na UTFPR, Dois Vizinhos-PR, em delineamento de blocos ao acaso com esquema bifatorial com três repetições. Os tratamentos principais foram seis doses de nitrogênio: 0, 40, 80, 120, 160 e 200 kg ha-1, e os secundários foram estádios de corte para ensilagem: início do florescimento com e sem pré-murchamento, e florescimento pleno sem pré-murchamento. Foi observado que a adubação nitrogenada promove redução no pH e no teor de material mineral da silagem de aveia, reduzindo os teores de fibras e elevando os de proteína bruta (PB), quando confeccionada no início do florescimento. O efeito de pré-murchamento no início de florescimento inibe a produção de efluentes e apresenta maiores teores de PB, sem efeito sobre os parâmetros de fermentação e de valor nutritivo. A ensilagem no estádio de florescimento pleno apresenta melhores padrões de fermentação, com pH e capacidade tampão menores, porém com menor valor nutritivo.UEL2014-08-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1443210.5433/1679-0359.2014v35n4p2185Semina: Ciências Agrárias; Vol. 35 No. 4 (2014); 2185-2196Semina: Ciências Agrárias; v. 35 n. 4 (2014); 2185-21961679-03591676-546Xreponame:Semina.
