Farmers and the milk processors agreed a voluntary deal which will mean contracts between them will be fairer and more transparent.
The agreement was made just hours after a huge protest outside a yoghurt plant where more than a thousand people,and their tractors, managed to stop some vehicles getting into the factory.
The farmers were angry that they get paid less than it costs to produce their milk.
Hundreds of dairy farmers from the East Midlands left their fields today to join a big protest in London. They say further cuts to the amount they receive per litre of milk will drive them out of business.
They're calling on the government to bring in legislation to help them counter what they say is an attack on their livelihoods.
