A Michigan dairy is cleaning up today after a fire tore through a barn Monday killing dozens of cattle.

The fire at Lockshore Farm was reported Monday morning by an employee after smoke poured from the 200- by 45-foot barn, according to the Battle Creek EnquirerIt reportedly took 40 firefighters from eight departments 20 minutes to battle the fire. High winds hampered the firefighting efforts.

Although an estimated 80 cows died in the blaze, some animals were able to be rescued.

“It was well involved when we got here,” Lt. Dennis Barnum of the Hickory Corners Fire Department told the Enquirer. “It was a calf barn and some of them were able to get out.”

According to MLive, the metal roof of the barn collapsed, complicated firefighting efforts. Firefighters had to use front-end loaders and Bobcats to spread the burning hay, straw and sawdust to put the fire out.

The cause of the fire is still under investigation.
