Online Published on 20 June, 2023. Abstract The availability of information regarding spontaneous brain lesions in Indian ruminants is inadequate. So, in the present study altogether 61 brains of different age groups of animals were studied consisting of brain from 10 sheep, 30 goats and 20 cattle of either sexes, which were collected from Postmortem facility of ICAR-IVRI, Izatnagar and one brain of cattle, received from the field to rule out bovine spongiform encephalopathy (BSE). Grossly, mild engorgement was obvious on all the surfaces of the brain of all the fallen animals (50), except in 10 sheep, where cortical plexus, parenchyma, and choroid plexus were moderately engorged. Microscopically, brain sections of 10/10 sheep, 6/30 goats and 9/21 cattle showed spontaneous lesions that included both vascular and inflammatory changes. Vascular changes were recorded in brain sections of 10/10 sheep, 4/30 goats and 5/21 cattle. The brain sections of 2/10 sheep, 2/30 goats and 4/21 cattle presented inflammatory changes in addition to vascular changes. The vascular changes in brain sections of 10/10 sheep were due to HCN poisoning, whereas in 4/30 goats and 5/21 cattle were mainly due to apoplectic reaction during death. The etiology of inflammatory changes in brain sections of 2/10 sheep, 2/30 goats and 4/21 cattle in form of mild meningitis and perivascular cuffing, could not confirmed. It may be concluded that the brain lesions recorded in the present study were general and frequent in occurrence. Top Keywords Brain, Ruminants, spontaneous lesions. Top |
