How long does it take for a calf to get over pneumonia?
Pneumonia is a respiratory disease that causes inflammation of the lungs. An infection in pre-weaned calves can reduce milk production later in life by 10-15% depending on the severity. But if you catch it early – in the first two-to-three days – calves are much more likely to recover fully.
When should a calf be vaccinated for pneumonia?
It provides protection against two viral causes of pneumonia, RSV and PI3 viruses and the bacterium Mannheimia haemolytica. Calves can be vaccinated from two weeks of age. The vaccination program is two shots four weeks apart. A booster dose should be given before the next period of risk.
At what age should calves be vaccinated for blackleg?
For example, blackleg is a rapidly fatal disease of calves. Calves should be vaccinated for blackleg by 3 to 4 months of age when the temporary immunity from the dam has declined and the calf’s immune system can respond to the vaccine.
How old does a calf have to be to get pneumonia?
Calves most frequently develop pneumonia between the ages of 2 weeks and 10 weeks, but it also occurs in calves up to 12 months old. Dairy calves, who are generally separated from their mothers shortly after birth, are far more likely to come down with pneumonia than beef calves, whose mothers usually nurse them.
What kind of pneumonia does a dairy calf have?
Dairy calves are likely to suffer from the disease at any age, with it manifesting itself as a chronic, coughing pneumonia, or as a more acute , enzootic calf pneumonia. Older dairy calves are also vulnerable after housing in the autumn.
When do suckler calves start to get pneumonia?
Older dairy calves are also vulnerable after housing in the autumn. Suckler calves are more likely to suffer from respiratory disease between two and five months of age, following weaning or transport from one herd to another. Outdoor reared beef suckler calves can also be severely affected by pneumonia ( Peters, 1986; Scott, 1997 ).
How are antibiotics used to treat calf pneumonia?
There are no antiviral drugs available for use in calves and, therefore, the main component of treatment for calf pneumonia is with antibiotics. More antibiotics are available for the treatment of calf pneumonia than any other condition in calves, so choice relies on a number of factors.

Can a newborn calf get pneumonia in a humid barn?
A newborn calf in a drafty or humid barn (with saturated bedding, ammonia fumes that irritate lungs and airways) may get pneumonia. A primary viral pneumonia may be mild, but secondary bacterial invaders may move in after tissues are damaged by a virus.
