Resumen
In this study we used 16 crossbred cattle divided into four groups. The animals were kept in
feedlot and fed complete diet consisting of corn silage, corn meal, soybean meal and different
sources of minerals. Two experimental trials were conducted. During the first mineral kernel
was provided mixed diet, in the second it was forced. The aim of this study was to evaluate the
accuracy of external markers LIPE®, NANOLIPE® and titanium dioxide to estimate dry matter
intake and digestibility in cattle. The design was completely randomized split plot. The
estimated results by the three indicators for intake, digestibility and fecal output did not differ
statistically from the total collection data, demonstrating there was no interaction between
source of minerals and the results estimated by the indicators. Although when the LIPE® has
been used associated with Klason Lignin these indicators were not able to accurately estimate
intake.
