single and double marker methods were compared
in seven Nellore steers with average body weight
250 kg, and previously canullated in the rumen and
duodenum. The animals were fitted with
continuous-infusion pump that administered
CoEDTA solutions intraruminally. In addition, a
capsule containing Cr 2 O 3, and other, containing
external n-alkanes C 32 , C 36 were inserted into the
rumen of each steer. Internal markers indigestible
neutral-detergent fiber and acid-detergent fiber
(iNDF and iADF after 144 h in situ incubation) and
internal n-alkanes C 31 , C 33, C 35 were components of
the diet. Steers were fed with palisade grass
(Brachiaria brizantha cv. marandu) in two age of
regrowth, 30 and 60 days. The duodenal flow
experimental design was a factorial 2x2x12 while
omasal experimental design was a factorial 2x2x4.
Markers iNDF, CoEDTA and the combination
Co+iNDF were efficacious to estimate duodenal
dry matter flow whereas iNDF, iADF and the
Co+iADF combination were all efficacious to predict
omasal dry matter flow. In conclusion, the double
marker method for estimation of omasal and
duodenal dry matter flow was the most appropriate
considering the ruminal fiber digestibility.
