Resumo: Two external markers (chromic oxide and ytterbium chloride) and two internal markers (indigestible neutral detergent fiber-NDF and indigestible acid detergent fiber-ADF) were compared in order to determine the flow of dry and organic matter in the duodenum. Three steers with ruminal and duodenal cannulas were fed with roughage: concentrate ratios of 80:20, 60:40 and 40:60. As these ratios as well as animals and experimental periods did not show significant effects, only markers will be discussed. The flow of the duodenal dry matter were 3816.8, 3269.3, 2739.2 and 2713.2g/day and of the organic matter were 3305.1, 2841.6, 2392.2 and 2351.3g/day estimated by chromic oxide, ytterbium chloride, indigestible NDF and indigestible ADF, respectively. The coefficients of ruminal digestion of the dry matter expressed as a percentage of the total digested were 38.8, 57.8, 80.2 and 81.9% and organic matter were 48.4, 65.3 84.8 and 85.7, when estimated by chromic oxide, ytterbium chloride, indigestible NDF and indigestible ADF, respectively. It was concluded that different markers lead to different estimation of duodenal flow and indigestible NDF and indigestible ADF are equivalent markers.
