I think there's a linguistically-driven temporal misunderstanding happening here. A cow couldn't have a calf if it hadn't become pregnant.
But there's so much to the linguistics of animal husbandry and dairy that many folks don't know. It goes way deeper than just the milk-oriented terms in the article: Heifer versus cow, freshening and calving, steer versus ox versus bull, AI (not the LLM kind) versus natural service, the barn, parlor, and pasture, and more. Plus plenty of technical knowledge. If you're not hand milking, how many mmHg of negative pressure should you use? Do you use a surcingle, or a claw, or a robot?
Even in the milk-oriented terms, there are others not covered by the article. HTST and UHT aren't the only options, there's also LTLT. Pasteurization can be done in a pipeline, or in a vat. Smaller vats for home and small farm usage can be multi-purpose: I pasteurized milk and cultured yogurt in mine. Some folks even care about the specific proteins (A1 beta-casein versus A2), which is genetically determined by the cow (and can be bred for).
I got a cow in 2020 and there was a lot to learn.

Not just that. A cow couldn't be a cow if she hadn't become pregnant.
