“The only quantitative estimates of farmed animal welfare I’ve been able to find come from Bailey Norwood, an economist and agricultural expert. He rated the welfare of different animals on a scale of –10 to 10, where negative numbers indicate that it would be better, from the animal’s perspective, to be dead rather than alive. He rates beef cattle at 6 and dairy cows at 4. In contrast his average rating for broiler chickens is –1, and for pigs and caged hens is –5. In other words, cows raised for food live better lives than chicken, hens, or pigs, which suffer terribly.”
