Abstract
AGPT was performed with faecal samples and FAT was carried out on intestinal tissue. Only one (14.3%) out of seven and six (85.7%) by FAT out of seven was found to be positive. This clearly indicated the superiority and reliability of FAT over AGPT for the diagnosis of rotaviral infection in piglets.
It is further concluded that 0-day-old piglets which could not suck its mother even once are the best suited experimental animals for the study of porcine rotavirus diarrhoea. The optimum preexperimental observation time should be of 10 days duration to avoid stress factors and also to cull out weaklings. The characteristic clinical symptoms of the disease, gross lesions and light microscopy have been reported which may be helpful in the diagnosis of the disease. Superiority of any diagnostic technique is dependent on its percentage efficacy to detect the infection. Thus it is concluded that FAT is far superior to AGPT for the diagnosis of rotaviral infection in piglets.
