CHICAGO (Reuters) – Farmers from North Dakota to Iowa buckled down for some of the coldest weather in a generation on Wednesday, throwing extra rations to pigs or building igloos for chickens in the teeth of sub-zero temperatures and bone-chilling winds.
Some, like Kurt Line in Indiana, joked about the forecast. Line said he was working on his tax returns, something he usually puts off, rather than braving the cold to load corn for a local processing plant.
But temperatures expected to plunge in some areas as low as minus 40-F degrees, the point at which Fahrenheit and Celsius converge, are no laughing matter for an industry dependent on the elements.
Cargill Inc closed all its grain plants in the U.S. Midwest on Wednesday because of extreme cold – and will likely reopen them on Thursday after temperatures warm, company spokeswoman April Nelson said.
Tyson Foods Inc canceled two shifts at a pork plant in Waterloo, Iowa, while Hormel Foods Corp halted the hog slaughter at its processor in Austin, Minnesota, according to three people familiar with the operations. The companies did not respond to requests for comment on the closures.
The brutal chill was caused by the polar vortex, a mass of freezing air that normally spins around the North Pole but has made its way south to the United States.
Minnesota farmer Peter Bakken woke on Wednesday to three of his family’s cattle water fountains frozen. He spent the day spraying hot water to thaw the pipes and keeping a close eye on the weather forecast.
The family grows alfalfa and snow cover on the plants is insulating them from the bitter cold. But the weather is expected to warm this weekend, and then get cold again.
He said that could replace the snow cover with ice, which could kill the plants.
Cattle ranchers Joey Myers and her fiancé, Scott Bailey, in Minot, North Dakota, were brewing even more coffee after staying up all night – for a second night in a row – to check on their animals.
They feared the minus 28-C temperatures with wind chills of minus 45 C could cause their pregnant cows to give birth early. Their heated barn is not big enough to house every animal, so they must keep watch for newborn calves to prevent fatalities.
Ron Prestage, president of one of Iowa’s biggest hog producers, Prestage Farms, said his company had been stocking up on feed to last at least until Friday, and was making sure heaters and water lines were running at hog barns.
“As cold as it’s going to be, water lines are a critical factor,” he said.
Most U.S. crops are planted in the spring, but the winter wheat crop sown in some areas could be at risk if the cold continues.
The freeze was also a concern for the smallest of farmers.
Backyard chicken owners in the Midwest flocked online for advice on how to protect their birds, with some on the chat forum at BackyardChickens.com asking if they should add a heating pad for their poultry to stand on.
Others suggested putting extra tarps around the coops to keep chickens dry and coating exposed chicken skin with petroleum jelly to ward off frostbite.
In Chicago, Lynn Ankney and her family have been double-checking their backyard coop, making sure there are no drafts around their Rhode Island Red and Black Australorp hens – and using snow that accumulated in recent days to build an igloo around their coop for extra insulation.
On Wednesday morning, she checked on her birds. They were safe and sound.
