The first farm-gate price rise of 0.5ppl to 29.5ppl will kick in from December 1, followed by a further 1ppl increase to 30.5ppl from February 1.
The increased milk price will be offered to all dairy producers supplying the group, except those in Tesco and Sainsbury supply groups, which each have their own milk pricing arrangements.
The move is widely seen as a response to falls in the supply of UK milk. According to Rural Payments Agency provisional figures, October milk production stood at 993.1 million litres, down a huge 69.1m litres (-6.5%) on October 2011.
NFU Scotland's milk policy manager George Jamieson commented: "Muller Wiseman has raised the bar and a milk price of 29.5ppl for December would, historically, be considered a good price – but with costs above 30ppl it must be taken in context. Not only are milk price increases needed now, but they are justified. Milk production on farms continues to plummet, and volume is unlikely to lift before spring. In addition, commodity values are rising, so further price rises are expected by all producers regardless of who they sell their milk to.
"NFUS's market formula indicates that a price based on AMPE and MCVE [price indicators for butter, powder, commodity cheese and whey] shows that the market should be returning at least 30.5ppl at the farm-gate. Cream, often used as a driver to bring prices down, is now more than £1500 per tonne and likely to rise in the run-in to Christmas."
