Here is an interesting article from the Missouri Ruralist describing how three different farm families have adapted their cattle farms to respond to changing markets as well as changing climate conditions to make sure that their farm is sustainable and can be handed down to the next generation of their farm families. In all three cases, they made changes to their herds as well as the technology that they use to take care of their cattle. Many farm families that I know of are constantly considering whether their mix of crops or livestock are the best use of their limited resources and if they can be economically sustained over generations. This is true whether they are using new rotations of existing crops, adding different crops to the mix, or switching to a different type of production altogether.
