Curtin Farms in upstate NY milks 3500 cows twice a day using this 60 cow rotary carousel. The cows are trained to get on at the beginning and back off at the end. The milking machines keep tract of the amount of milk and flow rate of the cows and automatically detach when the cow is done. The detached teat cups are then disinfected with a spray and ready for the next cow.
