An IFA statement said last night that liquid milk producers were being driven to protest by milk price wars between retailers, much of which was based on imported product.
"The current rock-bottom prices at which the main retailers are selling some of their milk is not economically sustainable unless farmer milk prices are cut. Indeed, some producer groups have already been advised by their dairy that such cuts would be required," said the statement.
"Also, much of the cheap milk is imported product. Those same producers could face a reduction in the quantities of milk they are required to produce daily by contract," it added.
