That's only one way to do it, probably the most efficient one for mass farming. In my country there is a similar delicacy, but instead of tube traditionally geese were fed by hand. Farmers would prepare balls of food, and then those balls were pushed into the geese's beak and down the throat by hand, until it's totally full. This is more time consuming than using a funnel and a tube to just pour the food.
