See how they specified “beef” dairy herd. They are talking only about the livestock. The animals. The veal. The cattle they breed. The animals they cull and sell. They aren’t talking about the lactating products.
Then you have milk. The product. Lactating dairy cows have a productive phase when they are kept specifically and separately to produce milk. I know it comes off as cruel but in agriculture animals are livestock and thought of in terms of lineitems when listed out.
I hope that helps. It’s a bad graph, the creater carved out specific data points for their own personal politics which makes it hard to read. (Hence the cute notes littered around the chart). I too would have wrapped dairy cows and milk production into one line.

What no one ever considers is what is happening right now in real time. They are actively pushing out the troops that would object morally to bad orders. The administration doesn’t care if they are left with inferior troops, as long as the ones they have left will follow orders blindly and without question.
