In the alps, I met up with some friends who had a goat farm, but their production as much smaller. They had about 100 animals. Would have been interesting to see an industrial-sized farm.
I'm guessing the rotary parlor isn't operational 24 hours. 550 goats a day, at 40 per round is about 14 rounds, so possibly 2 rounds per hour. Can you really milk 550 goats in 8 hours?
