Question: how much milk does a 1 month old calf drink?
Answer: Common dairy industry practice is to feed unweaned calves around 10% of calf body weight in milk daily. However, this amount of milk is about half of what calves would typically drink (around 10 litres of milk over 8-12 feeds per day) in the first month of life if a calf were able to suckle from its dam.
