Researchers at the U.S. Meat Animal Research Center in Clay Center, Nebraska collected several years of data on 110,000 calves, and noted two seasonal peaks in the incidence of BRD. One peak occurs from birth through around 20 days of age, and another takes place when calves reach 70 to 100 days of age.
