Today, welfare science is a rigorous discipline. Scientists measure cortisol levels (stress hormones) in factory-farmed chickens or analyze lameness in dairy herds to create quantifiable improvements. The welfare approach has led to tangible wins: the banning of battery cages for hens in the EU, the end of cosmetic testing on animals in many countries, and the rise of "certified humane" labels in grocery stores.
In response to growing public awareness and concern, governments and institutions have implemented various measures to protect animal welfare:
