Pneumonia, or bovine respiratory disease, is the second-highest cause of mortality in preweaned dairy calves and the highest cause of mortality in post-weaned dairy calves.
Stress doesn’t just impact the hardworking dairy producer, it can also impact our calves. External stressors and management factors can compromise their immune system and make them susceptible to respiratory disease.
Pneumonia, or bovine respiratory disease, accounts for more than 24% of preweaned heifer deaths and 58.9% of weaned heifer deaths on United States dairies, but there are ways to boost calf immunity and fight back against BRD.
