Riled farmers led two cows through a Stafford Asda on Sunday to protest at how little supermarkets pay for milk.
A video documented the protest in which a campaigner complained "milk should not be cheaper than a bottle of water," while parading the cows around the store.
Accompanied by over 50 protestors, the stunt quickly saw police called to the scene.
A statement from Staffordshire police said: “Officers were in attendance to ensure that the protest remained peaceful and minimal disruption is caused to the general public.”
The protestors set about removing milk from shelves adding they were set to visit a Lidl in Stafford and an Asda in Wolstanton to repeat the act.
British dairy organisation AHDB Dairy claims that British farmers need to receive 30p per litre to cover their costs.
In June it claimed that the average cost sat at only 23.01p.
