How much do cows suffer in the production of milk? I can’t answer that; understanding animal experience is hard. But I can at least provide some facts about the conditions dairy cows live in, which might be useful to you in making your own assessment. My biggest conclusion is that cows made better choices than chickens by making their misery financially costly to farmers.

Life Cycle

The life of a dairy cow starts as a calf. She is typically separated from her mother a few hours to a few days after birth and, to reduce disease risk, held in isolation. Cutting edge farms will sometimes house calves in pairs. This isolation is clearly stressful for a baby herd mammal and her mother, but I didn’t find any quantification of that stress that I trusted.

Calves will be bottlefed until weaning at 6-8 weeks (4-6 months earlier than beef calves). After weaning and vaccinations they can be introduced into a herd. At large farms (where most cows live), they will move in and out of different herds through their lifecycle. This is more stressful than being embedded with your friends for life, but again, I found no [...]

(00:44) Life Cycle

(02:43) How much time do dairy cows spend outside?

(04:21) By humaneness standard

(06:00) When indoors, how confined are dairy cows?

(06:33) What is the disease load of dairy cows?

(08:15) Euthanasia

(08:58) Most notable: calves are 2x as likely to die unassisted in small farms than large, but have ~the same likelihood of euthanization. For adult cows the gap is reversed and much smaller. It seems really unlikely those calves all had painless heart attacks, so we can assume days if not weeks or months of suffering.
