respiratory disease, young dairy calves, mortailtiy rate, cost
Respiratory disease is the second leading cause of death losses (scours is the first) in un-weaned heifer calves. Respiratory problems have increased by 34 percent in the last 20 years, causing nearly 21 percent of all newborn calf losses (NAHMS 2007). Heifers that survive continue to perform poorly as adult cows. In order to prevent this costly problem, it is important to address both determinant and predisposing causes.
