I think back in the day most farms consisted of both agriculture and livestock, but I think, there must have been exceptions.
I'm also especially interested in small-scale family-based farms. The period of time I am most interested in, is the early 19th century (let's say from 1800-1820).
While I'm mostly focusing on England, situations in other locations will also be helpful.
Researching, I found that the prices for cereals went up quiet high around that time and it seems, that there was a lot of agriculture as I found that fallow land decreased a lot from the late 18th century on.
But all studies I found about farming, only focused on agriculture without paying attention to farm animals or did not go into detail about the types of farms at that time and delivered only a general overview.
