Weaker wholesale markets and a large availability of milk are reported to be driving the cuts.
Muller producers will receive a May price of 40p/litre for a standard liquid litre of 4% butterfat and 3.3% protein, including its 1p/litre advantage premium.
Richard Collins, head of agriculture at Muller, said: “With ongoing market pressures we must reduce the price we pay to our supplying farmers by 2.5p/litre. Millions of people buy our dairy products every day and we remain committed to paying a competitive milk price and ensuring security of supply.”
Barbers will pay its producers 39.1p/litre in May for a standard manufacturing litre of 4.2% butterfat and 3.4% protein.
Dairy farmers supplying Saputo will see prices fall by 2.5p/litre to 40p/litre for May (for a manufacturing litre), while those supplying Glanbia will be subject to a 4.75p/litre price cut to 34p/litre, according to milkprices.com.
Freshways is standing on with a May milk price of 41p/litre for a standard liquid litre.
