Scotland's biggest pig processor is set to run out of carbon dioxide on Tuesday, leaving it in danger of welfare issues such as overcrowding.
SPP chief executive Andy McGowan told the BBC that the abattoir would start to see animal welfare issues develop within a few days because of overcrowding.
"We can send some pigs to England, to our sister factories at Tulip. But that is not a long-term solution. They, too, are seeing CO2 shortages," he said.
