Total lifespan is dependent on a lot of factors. But YES moving to dairy as a population shortens your lifespan by greatly increasing a bunch of sicknesses. See "the china study" for more in-depth info.

Reading the Wikipedia article on the "china study" doesn't seem that it's all definiteley related to dairy (or animal food consumption).
