Pesquisa do estado de Minas Gerais (FAPEMIG) / Objetivou-se determinar os efeitos da associa??o entre milho mo?do ou silagem de milho reidratado com ureia convencional ou de lenta libera??o para os par?metros de consumo e digestibilidade de nutrientes em bovinos de corte. Utilizou-se dois consecutivos quadrados latinos (4x4) com dura??o de 56 dias, representado por quatro tratamentos (T1 milho mo?do + ureia comum, T2 milho mo?do + ureia protegida, T3 silagem de milho reidratado + ureia comum, T4 silagem de milho reidratado + ureia protegida) em quatro per?odos experimentais de 14 dias cada, com quatro animais em cada delineamento experimental. Os consumos de mat?ria seca (MS), prote?na bruta (PB) e de nutrientes digest?veis totais (NDT) n?o foram influenciados pelos tratamentos (P<0,05), no entanto houve efeito significativo (P<0,05) para os consumos de fibra em detergente neutro (FDN) e fibra em detergente ?cido (FDA), assim como tamb?m para a digestibilidade verdadeira da mat?ria seca (DVMS) e digestibilidade aparente total da PB (DapPB), da FDN (DapFDN) e FDA (DapFDA). As associa??es entre silagem de milho reidratado com a ureia comum ou a protegida demonstraram efetivo incremento na qualidade nutricional das dietas T3 e T4, pois houve redu??es no consumo de FDN e FDA e aumento nas digestibilidade aparente da MS, PB, FDN e FDA, o que possibilitou inferir que houve o sincronismo nutricional para as referidas dietas conforme os referidos par?metros nutricionais. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Zootecnia, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2017. / The objective of this study was to determine the effects of the interaction between ground corn or rehydrated corn grain silage associated with conventional urea or slow-release urea in the parameters of intake and nutrient digestibility. The experimental design was a Latin Square (4x4), lasting 56 days, represented by four treatments (T1 ground corn + common urea, T2 ground corn + slow-release urea, T3 rehydrated corn silage + common urea, T4 rehydrated corn silage + slow-release urea) in four experimental periods lasting 14 days with two repetitions (eight animals) resulting in two simultaneous Latin squares. The intake of MS, PB and NDT were not influenced by treatments (P <0.05), however there was a significant effect (P <0.05) not only for NDF and ADF intakes, but also for DVMS, DapCB, DapNDF and DapADF. The associations between rehydrated corn silage with common or protected urea increased the nutritional quality of the T3 and T4 diets, because there were reductions in the consumption of NDF and ADF and increase in the apparent digestibility of MS, CP, NDF and ADF, making it possible to infer that there was nutritional synchronism for said diets according to said nutritional parameters.
