FBS is growing the chicken-culture. The fact that it's bovine is ancillary, it's just a convenient source of the good proteins for organism development as we have a whole system in place to grow and slaughter cows already. There are some technical problems with FBS as well, it varies in quality and in composition of the component proteins, so a synethetic/plant alternative that could be adjusted for different purposes would be useful in the lab as well.
