Resumo: Cannulated cows were allocated to a cross-over design to evaluate the technique for determination of volatile fatty acid (VFA) clearance by infusion of marker solution into intact ruminal digesta, and verify the technique sensibility to the variation in the diet. Animals received diet of forage or forage plus concentrate and infusion of valeric acid and Cr-EDTA solution into intact or evacuated ruminal digesta. The total fractional rate of VFA clearance (FRVFAC) was estimated by the exponential decay of valerate over time. The passage FRVFAC to the omasum was assumed as the decay in ruminal Cr concentration and the absorption FRVFAC was estimated by the difference. The total FRVFAC and absorption did not differ between techniques. The passage FRVFAC, however, was lower when the marker solution was added into the evacuated digesta, probably reflecting the destabilization of the rumen environment during the evacuation and the largest volume of fluid observed in animals with evacuated digesta. In conclusion, the infusion of marker solution into intact digesta with homogenization performed by ruminal motility could be usable for the VFA ruminal clearance determination since it seems to cause lesser disturbance in the ruminal environment.

Os animais receberam dieta de forragem ou forragem juntamente com concentrado e infusão de ácido valérico e solução de Cr-EDTA na digesta ruminal intacta ou evacuada. A taxa fracional total de depuração de AGV (FRVFAC) foi estimada pelo decaimento exponencial do valerato ao longo do tempo. A passagem FRVFAC para o omaso foi assumida como o decaimento na concentração ruminal de Cr e a absorção FRVFAC foi estimada pela diferença. A FRVFAC total e a absorção não diferiram entre as técnicas. A passagem FRVFAC, entretanto, foi menor quando a solução marcadora foi adicionada na digesta evacuada, provavelmente refletindo a desestabilização do ambiente ruminal durante a evacuação e o maior volume de líquido observado em animais com digesta evacuada. Em conclusão, a infusão da solução marcadora na digesta intacta com homogeneização realizada pela motilidade ruminal poderia ser utilizada para a determinação da depuração ruminal de VFA, uma vez que parece causar menor distúrbio no ambiente ruminal.Universidad CES2020-06-24T12:55:35Z2020-06-24T12:55:35Z2019info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfRESENDE JÚNIOR, J.
