The disease is primarily seen in sucklings from 2 days and older. The process is often serious with watery scours and high mortality at times.
At the age of 2–3 weeks, milky/pasty rotavirus-induced diarrhoea may be seen.
The mortality rate is low, but it often affects almost the entire litter.
Following rotavirus infection, the pigs may lose body condition but will in most cases only experience a short period of reduced growth.
The virus is spread with the manure, and rotavirus is highly resistant to desiccation and the most common disinfectants.
The mortality rate is low, but reduced growth and a number of pigs with impaired body condition can be expected after a rotavirus outbreak.
Rotavirus prevention is based on immunisation of the pigs through the colostrum as well as a good standard of hygiene and a good local environment in the farrowing pens.
Stalosan F is effective in combating rotavirus in pig houses.
