Milk 3 to 4 kg

That is a low-yield buffalo. For only three to four liters a day, do not pay premium money. Look for a healthy Surti or a lower-end Mehsana if your budget is tight. Check that the udder is soft, teats are even, and the animal is eating well. If you want better milk income, Murrah is the stronger dairy choice. If you are buying, I can show you buffalo options on Pashushala.
