Question: how many litres milk does a cow produce?
Answer: Whereas a beef-suckler cow would naturally produce around 4 litres of milk per day, a dairy cow will produce an average of 28 litres per day over a period of 10 months. During peak lactation, a high-yielding cow may produce as much as 60 litres per day and up to 12,000 litres over her whole lactation.
