How much feed should I give daily?

For a lactating cow, give about twenty to fifty kilogram green fodder, four to eight kilogram dry roughage, two to eight kilogram concentrate depending on milk yield, and one hundred to two hundred gram mineral mixture daily. Keep clean water always available, usually fifty to one hundred liter a day. If she is giving high milk, the concentrate should be around twenty percent protein. If you tell me her milk yield, I can guide the ration more closely.
