A further study would be the historical symbiotic relationship between humans and dairy animals. Goats may be more important than cows, as from what I’ve heard, they are more commonly used for milk production than cattle. For cattle regions, the majority of the males were castrated and used as draft animals. If you read Scottish history, you’ll find references to wealthy people owning 1,000 yoke of oxen. That’s 2,000 ox, that’s a lot to feed. Since they didn’t have mechanized agriculture, they needed the oxen to plow the fields for planting. But if you have 1,000 yoke of oxen, you need 1,000 plowmen to drive ’em. I would imagine that just about every able bodied man in the district was put to work during the planting.
