Cows must be brought to the milking parlors as cleanly and calmly as possible in order to milk them effectively. The milk is removed from the cows' teats using suction tubes after the cows are herded into the parlor, their udders are cleaned with iodine, and the tubes are attached. A technique for drafting certain cows when they leave the parlor is essential. The gathering of milk is the single most crucial task on any dairy because it is the main product and the key source of income for producers.
