BATTLE CREEK, Neb. (AP) — A Battle Creek dairy farm continues to recover from a roof collapse that killed several cows on Christmas.

Mike Henn of Henn House Dairy says his workers, neighbors and a construction crew have been working long hours to keep operations running. Henn calls it one of the most stressful times of his life.

The roof on Henn's loafing barn — where cattle rest and sleep — gave in under heavy snow, killing several cows and trapping others. Workers tried for four hours to rescue the trapped animals, but some had to be put down.

A construction crew came out on Christmas to make repairs to the barn and secure the roofs on his other buildings.

Henn is currently milking about 850 cows. He wouldn't give specifics about his losses.
