The chine is normal, to doe is just very over stretched in the front end giving the spine a very curved slope look. If the doe was not over stretched she would look really nice (if they weren't pulling her front end up).
Well, keep on mind that I am not a dairy person but here's my two cents. In the pic she looks a bit odd, uncomfortable. Her back is arched, maybe because her legs are too far back? It is hard to tell if it is a bad set up or conformational. My instinct is that her back is naturally more level than it looks. That said, if there is a dip directly behind her shoulders in person or in other pics, that would indeed be a weak chine.
