  Some field theory aspects can be addressed holographically by introducing
D-branes in the string theory duals. In this work, we study this issue in the
framework of a dual of N=1 YM, the so-called Maldacena-Nunez model. Some
supersymmetric embeddings for D5-brane probes are found and they are
interpreted as the addition of fundamental flavors to the gauge theory. This
allows to give a dual description of some known aspects of N=1 SQCD and to
compute a mass spectrum of mesons.
