Bovalto Respi 3 contains strains of parainfluenza virus 3, bovine respiratory syncytial virus and Mannheimia haemolytica serotype A1.
Bovalto Respi 4 combines the three pathogens in Bovalto Respi 3, with the addition of bovine viral diarrhoea virus.
According to the company, calf pneumonia costs are around £43/€49* per dairy calf and £82/€93* per suckler calf1.
Boehringer’s vet adviser Ailsa Milnes said: "The majority of these costs are made up of mortality, slower growth rates and reduced lifetime performance.
"It is worth remembering that calf pneumonia can cause irreversible damage to the lungs which means that, even if the animal recovers, its lifetime performance suffers and it will be more susceptible to disease in the future.
"Bovalto Respi 3 and Bovalto Respi 4 are the only vaccines available to demonstrate six months of immunity by challenge for all pathogens, and calves develop protective immunity three weeks after completion of the primary vaccination course.
"Now, with the added flexibility of being able to administer the vaccines to pregnant cattle, the overall level of respiratory disease in a herd will hopefully fall and overall health status improve as a result."
