Figures taken from AHDB estimate that calf pneumonia is costing the industry approxiamately £50 million pounds a year. With individual cases costing £30- £80 per case, it's worth looking at preventation strategies. It's also important to note that respiratory diseases such as pneumonia can affect the cow's performance for the entire of its life, with reduced growth rates and lower milk yields.
Calf pneumonia or Bovine Respiratory Disease (BRD) is a multi-factorial disease which results in inflammation and damage to the tissues of the lungs and respiratory tract. It usually occurs in young housed cows, with winter being a particular issue if ventilation isn't adequate.
So what are the signs that your calves might have pneumonia?
Pneumonia can be due to a number of different factors and can be categorised as:-
This form of pneumonia occurs when any solid material is inhaled and enters the lungs. The most common cause is improper use of esophageal feeders when administering colostrum. Aspiration also may occur during a difficult birth when a calf inhales some meconium (first manure) or amniotic fluid. A common source of aspiration in older calves is nipples with holes that are too large, which allow calves to consume milk too quickly.
The three primary organisms that cause bacterial pneumonia in calves are Pasteurella multocida, Mannheimia hemolytica, and Mycoplasma species. “Bacterial infections that occur in the first few days of life result from infection within the dam, aspiration or contaminated colostrum. As calves grow older, new infections typically are acquired from the environment or other sick calves.”
BRSV, IBR, PI3 and BVDV all can instigate pneumonia in calves. “A viral pneumonia then predisposes calves to acquiring bacterial pneumonia.”
So what can you do to reduce the risk?
