Protesting farmers from far and wide are due to gather again at Robert Wiseman Dairy near Bridgwater tonight at 8pm (Sunday) to drive home their milk message.
The protest is being organised by Farmers for Action which is also staging demonstrations at Droitwich and Market Drayton branches of the dairy at the same time.
It follows similar action on Thursday night when 500 farmers drove tractors and other heavy agricultural machinery to create a blockade at the North Petherton dairy.
Robert Wiseman, which is situated just off junction 24 of the M5 motorway, has said it is to cut the amount it pays farmers per litre of milk by around 4p.
Furious farmers say they are now losing money on every litre of milk they sell.
