The Indian dairy industry is the largest in the world, producing over 140 billion dollars worth of milk and dairy products annually. It is made up of over 10 million smallholder dairy farmers organized into local cooperatives. The top states for dairy production are Delhi, Punjab, Mumbai, Gujarat, and Bihar. The Amul cooperative, founded in 1946, plays a major role in the industry and was responsible for India's white revolution that made the country a top dairy exporter. The dairy industry provides livelihoods for millions of rural Indians and continues to grow to meet rising domestic demand.
