The Bihar State Milk Co-Operative Federation Ltd. (COMFED)was established in 1983 as the implementing agency of Operational Flood (OF) programme of dairy development on “Anand” pattern in Bihar. All the operations of erstwhile Bihar State Dairy Corporation were handed over to COMFED.

Till the end of OF programme in March 1997, there were five district level Milk Producers’ Cooperative Unions covering eighteen districts of Bihar. The dairy development work continued  and at present there are eight district level milk unions covering thirty three districts of Bihar. Comfed develops the districts first in terms of dairy development coupled with capacity development of milk producers to shoulder broader responsibilities and then hands over the entire operations to the representatives democratically elected by the milk producers.

Comfed is serving the consumers of Jharkhand also and there are three dairies at Jamshedpur, Ranchi and Bokaro. These dairies are serving a good number of towns and cities of Jharkhand in Ranchi, East & West Singhbhoom, Hazaribagh, Gumla, Khunti, Palamu, Lohardaga, Bokaro, Dhanbad, Giridih etc. Sudha Milk and some products are now available in Delhi/NCR region and Uttarakhand also apart from a number of towns and cities of U.P. and West Bengal.

The Farmer’s Training Centre at Patna, Barauni and Begusarai provides training to the milk producers and society functionaries in various aspects of dairying, clean milk production, society operation, artificial insemination etc.
