Dear student.
Dairy farming deals with production of milk. A dairy farm is a place where animals like cow, goat, sheep, and yaks are kept and raised to produce good quality of milk.This milk is then distributed from the farms to the surrounding region.
Ranching is the practice of raising and grazing livestock like sheep for wool. Under ranching, farms are exclusively used for raising livestock like herds of cattle, sheep or horses.
