Fresh Milk and Eggs on Board

It is known that famous Bennett's Mega-Yacht "Lysistrata" built in 1901 had a stall on her board for 2 cows to supply daily the owner super-fresh milk. There were also a dozen hens there to supply him super-fresh Eggs.
Is there such practice on modern Mega-Yachts?
I guess present-day owners need extra-quality food no less than Bennett a hundred years ago.
