Pneumonia issues

I have had a number of reports this week of pneumonia in calves and weanlings in sheds. Recent mild weather has meant sheds with poor ventilation have struggled to get enough air movement and this has led to health problems. Stress is a big factor so make sure animals aren’t under any nutritional or parasite stress. Remember in the face of an outbreak not to stress calves too much and to seek veterinary advice. While vaccinating calves intranasally can work quicker and give faster cover, vaccinating in the middle of a pneumonia outbreak when animals have high temperatures and animals are actively shedding virus will hinder the vaccination. If dosing, weaning or castration are planned, wait until all calves are fully clear of pneumonia until proceeding with these tasks as stress could lead to a relapse.
