Porcine rotavirus
Piglet diarrhoea and mortality are gaining importance and the viral agent which is highly incriminated in such episodes is porcine rotavirus. The clinical features and the pathological conditions are similar to those noticed in new born calves. The disease is characterized by short incubation time of 16 to24 hr and is invariably associated with low intake of colostrum and poor hygienic conditions. Inoculation of sows with inactivated vaccines promotes high levels of rotaviral antibodies in the colostrum for longer periods and helps the neonates to ward off the infection during their vulnerable period.
