Problems with Blender files and animation

Hi, i have a problem with blender files and animations. I have made a simple 3d model with blender and has an animation. I can share the object if you like. When i export the file as an fbx and change the height to z and forward to y everything is ok. When i use the blend files there are the following problems. If i import the animation in unity the object turns 90 around the x axis and the animation does nothing. The object contains the animation but the object stands still and do no move. Has anyone encounter these problems?

off course i can use fbx, that is what i do now. I just wan to know if it is possible not to export to fbx
