Texas dairy farm explosion claims lives of 18,000 cows.

An explosion and fire at a dairy farm in West Texas killed 18,000 cows, becoming the largest known single-incident death of cattle. The cause of the explosion is unknown, but officials suspect a malfunction in a piece of equipment. The loss of livestock will have a large financial impact on the farm as each cow is valued at roughly $2,000. The incident is the largest single-incident death of cattle since the Animal Welfare Institute began tracking barn fires in 2013.
