Canada’s largest pork producer is closing down farms and laying off staff in Alberta and Saskatchewan in response to low prices.

Quebec-based Olymel LP announced it will be closing five sow units in southern Alberta and one in Saskatchewan to reduce its pig herd by about a third to about 40,000 sows. About 80 employees have been laid off.

In a news release, the company said the closures would result in a net reduction of about 200,000 market hogs annually to its Red Deer slaughter plant. The barn themselves will be wound down over the next several months and remain closed until market conditions improve.
