Three cases of posterior paralysis were observed in T x D variety of crossbred piglets at ICAR Research institutes pig unit during last one year. Piglets were unable to move after birth but suckling colostrums with support.
Average birth weight of affected piglets were less (0.86 ± 0.07kg) in comparison to healthy one (1.12 ± 0.05kg) and observed spastic extensions of the legs, particularly in hind legs. They were able to move its hind legs but unable to stand on them. Urination and defecation was normal.
Within 72 hours of birth all the affected piglets died. The disease is conditioned by an inherited recessive factor and termed as inherited congenital posterior paralysis.
