ABSTRACT
The aim of this work was to evaluate if the n-alkanes (C32) technique can be used to determine voluntary dry matter intake (DMI) and dry matter digestibility (DMD) in grazing donkeys. Two experiments were carried out; in trial 1 DMI and DMD were measured using n-alkanes in four caged donkeys. In trial 2, n-alkanes were used to predict DMI and DMD in six donkeys grazing a star grass sward (Cynodon nlemfluensis). Results from both experiments suggest that the n-alkanes technique can be used to predict DMI and DMD with similar results than those obtained with other more sophisticated or expensive techniques.
