Hundreds of farmers blockaded processing plants into the early hours of the morning in a protest against the price they are paid for milk.
Around 400 farmers gathered outside an Arla plant in Ashby-de-la-Zouch, Leicestershire.
They are furious angry over cuts of up to 2p a litre in the amount they receive from major milk processors.
They fear the cuts to payments will force them out of business, pushing up the price of milk to consumers in the long-term.
The action is the latest in a series of protests by farmers who are angry that they are to be paid less for their milk than the cost to produce it.
Dairy Crest is one of a number of milk producers that have slashed the price they pay farmers for milk after seeing the value of cream plummet this year.
It has admitted its milk price cuts "put pressure on our supplying farmers".
