MIDDLEBURGH — Farmers and firefighters rescued 150 trapped cows Tuesday night after a 20,000 square foot dairy barn collapsed under the weight of three feet of snow, officials said. About 25 firefighters and 20 local farmers descended on the building but had to shore up the walls before any rescue efforts could begin. The crew used a new Paratech stabilization kit and heavy-duty farm equipment to keep what was left of the barn standing, Devlin said. During the rescue, one cow rolled over onto the leg of a volunteer firefighter and twisted his ankle, Devlin said. The chief said he suspects the man badly sprained his Achilles tendon and that he was having medical imaging done Wednesday.
