The nutritional advantages of fresh milk every day are obvious, especially for growing children. One cow can produce up to 10 gallons of milk a day – or 200,000 glasses of milk in its lifetime. Dairy animals can also be a dependable source of income, as extra milk can be sold to raise money for school fees, clothes, and medical expenses.
