Resumo: | Objective: the aim of this experiment was to evaluate the effect of increasing levels of P intake on the P concentration in biological fluids of Santa Ines lambs. Methods: 18 animals were individually confined in metabolic cages for 35 days. Phosphorus levels in the diet were: 25% lower than the level recommended by the NRC (1985) (T1); the recommended level by the same agency (T2); and 25% higher than the recommended level (T3). The experimental design was randomized blocks following a repeat measure arrangement. Two experimental periods of five weeks were evaluated. Saliva, plasma, rumen liquor, feces and urine samples for P determinations were collected during last three weeks of each period, for four consecutive days. Results: for the lowest amount of P intake (1.87 g/day) corresponding to T1 (p<0.05), showed values of plasma P in average of 5.99 mg/100 ml, 42.91 mg of P/100 ml in saliva, 48.64 mg of P/100 ml in ruminal liquor, 0.19 mg of P/kg PV in urine and 1.27 g/day in feces. Except for urine, all values were lower (p<0.05) than T2 and T3. Conclusion: these values can be considered as adequate to maintain the levels of P in the different fluids, and normal for a satisfactory animal performance, indicating that the NRC (1985) P recommended value could be reduced. |

Métodos: 18 animais foram mantidos em gaiolas de estudo de metabolismo por 35 dias. Os níveis de P nas dietas foram: 25% menos P que o recomendado pelo NRC (1985) (T1); quantidade recomendada pelo NRC (T2) e 25% a mais que o recomendado (T3). O delineamento experimental foi blocos casualizados em esquema de medidas repetidas. Foram avaliados dois períodos experimentais de cinco semanas cada. As amostras de saliva, plasma, conteúdo ruminal, fezes e urina, para a determinação do P foram coletadas durante as três últimas semanas, em quatro dias consecutivos. Resultados: a menor ingestão de P (p<0.05) correspondeu ao T1 (1.87 g/dia). No T1, foram observados níveis médios de 5.99 mg de P/100 ml no plasma, 42.91 mg de P/100 ml na saliva, 48.64 mg de P/100 ml no fluido ruminal, 0.19 mg de P/kg PV na urina e 1.27 g/dia de P nas fezes. Estes valores, com exceção da urina, foram menores (p<0.05) aos observados nos T2 e T3. Conclusões: estes valores podem ser suficientes para manter os níveis de P nos diferentes fluidos dentro de faixas consideradas normais para um bom desempenho animal, indicando que os valores de P recomendado pelo NRC (1985) poderiam ser reduzidos.Facultad de Ciencias Agrarias, Universidad de Antioquia2019-12-20T12:46:03Z2019-12-20T12:46:03Z2012info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfBORGES, E. do E.
