How many liters of milk can a cow give in a day? 2-4 Ltrs, 10-20 Ltrs? But if we tell you that a cow can give 100 to 150 liters of milk in a day, would you believe it? The thing is shocking, but true. Chinese scientists claim that they have created a ‘super cow’ through cloning. Scientists have prepared 3 such cows, which will give 25 to 35 times more milk than a normal cow.
