Hello student,

For getting license to start the dairy farm you need to contact Municipality Corporation or local panchayats based on your place. If you are planning for large size farms the you need to get permission from pollution control board. The large food business require Central License. A State License is required if your dairy unit handles from 500 to 50,000 litres of milk per day or more than 2.5 MT to 2500 MT of Milk Solids per annum.

Hope it helps you...
