I would do 2 things:
1) To align particle transforms to face normals, use a Rotation operator set to surface alignment mode and also disable 'affect particle shape orientation'. That will cause only the transform to rotate, allowing you to orient particle Z-axes to the surface.
2) Use the Position Transfer workflow to simulate the particles on a static deer, and then transfer to the moving deer after. It will make your life a lot easier
There's an official example scene showing how to use that operator but it's pretty simple.
