The government opened Nalanda dairy in 2013 which is the Largest Automation based Dairy Plant in Eastern India. The establishment of Sudha was a result of White Revolution. In January 2021,the organisation had decided to make two new dairy plants in Bhagalpur and Purnia districts operational by the next three-four months each with a capacity of 2 lakh litres per day. The setting of new plants would help enhance the income of the milk producers of the region. In year 2020,Bihar Government started a dairy plant of 5 lakh litres per day and an animal fodder plant of 300 MT per day at Bihian. For setting up dairy plants and animal fodder plants in the state, Government had released a sum of Rs 53 crores to Comfed as first instalment out of Rs 234 crores. In 2018,Bihar State Milk Co-operative Federation, known as Sudha, planned at consolidating its market in Guwahati before expanding its reach to other states of the Northeast.
