How do farmers adjust to daylight savings time?

For urban and suburban folk who live by the clock, the spring and fall changing of the clocks results in a jolting shift of an hour in our daily routines (easier in the fall than in the spring).

For those more in tune with natural rhythms—seasons, livestock, crops—does it make any difference? Do dairy farmers get up an hour early and face a bunch of sleepy cows all moaning “What are you doing here? It’s not time yet.”? Do they adjust incrementally, like ten minutes a day, so as not to confuse the goats and chickens? Or do they just follow the sun all year round?

Kind of feeling it today and wondering how it is for other folks.
