Cattle ranchers in the US are braving the freezing weather to feed their stock through the cold snap.
Temperatures are reaching nearly minus 30 degrees Celsius with the wind chill, with a blast of icy winds and snow brought down from the Arctic.
Kansas rancher Debbie Lyons-Blythe says the cows are coping with the cold weather, but the bulls need to stay in sheds.
"The most important thing about those bulls is they're for reproduction.
"So it's really important that we do bed them down on straw so they don't lie on the ground, and get their reproductive organs frost-bit, because that would decrease sperm production."
She says school has been cancelled so her teenagers have been helping feed the cattle, and they all end the day with a pot of slow cooked beef stew.
She's posted photos of the cattle on her .
