The BVR photometric light curves of the eclipsing binary BD And were obtained in 2008 and 2009 .
We estimated the mass ratio of the system as 0.97 and the photometric solutions were derived .
The results show that BD And is a detached binary system , whose components have a little temperature difference of about 40 K. By analyzing photometric available light minimum times , we also derived an update ephemeris and found for the first time a possible periodic oscillation with an amplitude of 0.011 days and a period of 9.6 years .
The results indicate that the periodic oscillation could be caused by a third component physically attached to the eclipsing binary .
After removing the light variations due to the eclipses and proximity effects , the light-curve distortions are further explained by the pulsation of the primary component with a dominant period of \sim 1 day .
In accordance with the position of the primary component on the Hertzsprung-Russell diagram and its pulsation period , the primary component of BD And could be an excellent \gamma Doradus candidate .
It is rarely phenomenon that a component of the eclipsing binary system is a \gamma Doradus variable .
