Two groups of viruses, rotavirus and coronavirus, cause diarrhea in young calves. Rotavirus affects calves less than a week old (sometimes as young as 1 to 3 days) while coronavirus affects calves more than a week old. Most of the serious cases are in calves that have concurrent bacterial infections, creating severe and life-threatening diarrhea. These viruses by themselves are not nearly as dangerous as the combination. Spread of the virus is via contamination, as when a newborn calf nurses a dirty udder; the virus is present in feces of carrier cows.
Thereâs no effective treatment for viral scours except supportive therapy, reducing stress and keeping the calf well hydrated with fluid administered either orally or by IV if the gut is compromised by infection and dehydration. Antibiotics are usually given, however to combat secondary bacterial infection, as itâs the combination of viral and bacterial infection that generally kills a calf.
The best way to prevent viral scours is by maintain a clean environment for calving cows and newborn calves. If your herd does not already have these diseases, donât bring in new animals that might harbor them, if your herd has problems with viral scours, vaccinate cows several weeks ahead of calving so that their colostrums contains high levels of antibodies. To gain the protection, the calf must nurse the colostrums immediately after birth before he ingests pathogens. Itâs important to make sure that the calving area and the cowâs udders are very clean and the calf is up and nursing within an hour of birth.
There is also an oral vaccine that can be given to calves if cows were not vaccinated ahead of time, but it must be given to calves immediately after birth, before they encounter viruses in their environment. Consult your veterinarian for advice on vaccine products and how best to protect calves in your particular situation.
For a broad examination of the topic of viral diarrhea in calves, refer to Essential Guide to Calving (Storey, 2008).
