oh you’re right, forgot cows don’t produce milk when they didn’t just give birth. To be honest I just assumed cows gave milk since chickens are shown giving eggs, but there’s no mention about cows afai-remember.

OK looked it up so there is an instance where you see a cow milk factory. They push them drugs to increase their production (not a legal business kinda slavery-ish). It’s possible some others rely on recently pregnant cows to donate some extra milk, or maybe it’s more common to go with soy, almond, oat, etc.

In Beastars, animals like cows and chickens get paid for offloading their milk and eggs. There’s a whole side story about this chicken being very proud of her eggs and taking care of her body to produce the best quality product.

Is this related to nissan’s partnership? It’s not mentioned in the article
