In modern production, the bird is typically fed a controlled amount of feed, depending on the stage of the fattening process, the bird's weight, and the amount of feed the bird last ingested.[64] At the start of production, a bird might be fed a dry weight of 250 grams (9 oz) of food per day and up to 1,000 grams (35 oz) (in dry weight) by the end of the process. The actual amount of food force-fed is much greater, because the birds are fed a mash with a composition of about 53% dry and 47% liquid (by weight).
