Are your calves ready for housing?
All ages of cattle are susceptible to pneumonia however young stock are most vulnerable. In the regional vet labs in 2018 respiratory disease accounted for one third of all deaths in calves aged between one and 12 months of age. Common causes of pneumonia in calves include viruses like RSV, PI3 and bacteria such as Mannheimia haemolytica, Pasteurella multocida and Mycoplasma bovis. Risk factors leave calves more susceptible to disease.
Risk factors for pneumonia
Nutrition
The dry matter content of grass can be quite poor in autumn and calves may require additional feeding in the form of meal and in some instances forage too. Likewise, with vitamins and minerals, supplementation may be needed if deficiencies are suspected or diagnosed.
Parasites
Mild wet weather is perfect for hoose and it has been extremely prevalent of late. Lungworm in severe cases can result in death. A lungworm burden presenting as a cough in the batch can also predispose to secondary infections.
Environment
Stress factors such as overstocking and lack of shelter in paddocks may leave calves vulnerable. Once housed ventilation plays a leading role in controlling pneumonia. Increasing level of comfort (e.g. slat mats) along with adequate space, light and air plays a role in keeping animals healthy.
Vaccination
Vaccination should be used ahead of the housing period to provide immunity against the most common causes of pneumonia. Seek advice regarding which vaccination protocol is best for your calves.
