Resumo: | The objective of this work was to evaluate the effect of nitrogen sources, using sugarcane supplemented with urea, corn gluten meal-60 or soybean meal. It was evaluated Intake, total and partial apparent digestibility were evaluated using four rumen and duodenal cannulated crossbred steers. The treatments were evaluated in a 4 x 4 Latin square design. The total feces were collected to determine the apparent digestibility on the total intestinal tract. The indigestible acid detergent fiber (iADF) was used as marker of duodenal flux to determine ruminal and intestinal digestibility and dry matter daily flux. The DM, OM, CP, EE, DE, NDF, ADF and TC intakes and digestibility rates were influenced by nitrogen sources, and lower intake was observed in animals fed exclusively with cane sugar compared to animals fed the other experimental diets. Meanwhile the sources of nitrogen did not affect the total digestible nutrients (TDN) values. The RDP sources did not affect the total, ruminal, and intestinal nutrients apparent digestibility. However, the total, ruminal, and intestinal dry matter, and protein apparent digestibility were affected by the RDP sources. |

Os tratamentos foram: cana-de-açúcar, cana-de-açúcar suplementada com ureia, glúten de milho-60 ou farelo de soja. Foram utilizados oito novilhos canulados no rúmen e duodeno, distribuídos em dois quadrados latinos 4x4. Para se determinar a digestibilidade aparente no trato digestivo total foi utilizada a coleta total de fezes. As determinações das digestibilidades ruminal e intestinal e dos fluxos diários de matéria seca foram estimadas por meio da fibra em detergente ácido indigestível (FDAi) como marcador de fluxo duodenal. Os consumos de MS, MO, PB, EE, ED, FDN, FDA e CT foram influenciados (p < 0,05) pelas fontes de nitrogênio, sendo observado consumo inferior nos animais alimentados exclusivamente com cana-de-açúcar em relação aos animais alimentados com as demais rações experimentais. Entretanto, as fontes de nitrogênio não afetaram o consumo de NDT. As digestibilidade aparente total, ruminal e intestinal dos nutrientes não foram influenciadas pela adição de fontes de nitrogênio, com exceção da matéria seca e da proteína bruta.Editora da Universidade Estadual de Maringá2009-09-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpesquisa de campo; análise laboratorialapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/683110.4025/actascianimsci.v31i3.6831Acta Scientiarum.
