Shoppers in supermarkets were confused as pigs were let loose in supermarkets in the southwest of France.
French television station iTele tweeted a video of the pigs as they wandered through the supermarket in Agen Wednesday.
In addition to the supermarkets in Lot and in Garonne in the south west of France, farmers targeted dairy companies in Loire-Atlantique and dairy factories in Pas-de-Calais, among others.
These actions demonstrate a sharp rejection of President François Hollande's aid package of 600 million euros to help livestock farmers stay afloat.
The current situation is "impossible" for livestock farmers, says Philippe Chotteau, head of the economics department at the Institut d'Elevage, who carries out survey market trends on meat and dairy products on a national and global scale.
Meat and dairy farmers, unlike crop farmers, have been swamped in debts as falling pork, beef and dairy prices have prevented them from breaking even, let alone cover production costs, he told RFI.
