This fact sheet discusses reasons and precautions of feeding waste milk to dairy calves. Dairy producers feed a variety of liquid feeds to young calves after the initial colostrums. These liquid feeds include surplus colostrums, whole milk, transition milk, waste or discard milk, and milk replacer. Waste or discard milk is milk that cannot be sold for human consumption because it comes from cows treated with antibiotics for mastitis or other illnesses. Discarded milk losses range from 48 to 136 pounds of milk per cow per year. To reduce some of the economic loss, 38% of dairy producers feed waste milk to calves.
