when the animals were switched over to the dry total mixed ration,/
their concentrations sharply decreased to quite low concentrations./
Both the VIS-NIR spectra of the plasma and the subcutaneous fat color are useful in discriminating steers fed with finishing diets,/
but neither method is not suitable for discriminating between the Pirenaica and Parda de Montana˜ breeds./
The calibrations that were developed to estimate the lutein and -tocopherol concentrations could be classified as poor./
The calibration used to estimate the -carotene plasma concentration was useful for analytic purposes,/
but it should still be improved./
The DESIR method can be interesting to monitor the plasma concentrations of carotenoids and tocopherol in live animals,/
whereas the measurement of the subcutaneous fat color of the carcass is a simple and fast method for discriminating,/
post-mortem, /
animals that were fed diets with different carotenoid contents./
