This is the finished horse rendered in real time. The normal map is generated from a high poly ZBrush model. The hair texture fallows the hair added to the ZBrush model. The specular map contains dark and light strands of hair to add to the hair texture. Poly count 2386.

Some Views of the Model with Wire frame.

Here is a demonstration of what the normal map adds to the model. If you hover over the button you will see that the definition of the model is lost. If I was working on a game engine that didn't us normal maps I would approach the defuse map differently, I would put the muscle definition on the model using general lighting on the defuse map. This would create a similar look as the normal map but not be as realistic.
