Hi all we are looking at upgrading our existing alfa laval memory box at back of parlour currently just type in ammount of cake each cow has as she enters parlour .We have been looking at replacing it with a dvlec box to control the feeders but would realy like to go up to the dfms box that davlec make which allows connection to pc and ear tag readers so this then as i understand it would feed the cows according to yeild that we enter into the pc on a 2/4 week basis i guess was just wondering if anybody had a system in place like this and your thoughts please
