Present study was aimed to investigate the mortality among a flock of Ganjam sheep and goat during December, 2016 in Odisha. These breed of small ruminant mostly reared in nomadic pattern by certain “Gola” community with native tract mostly in south-eastern and eastern-ghat of agroclimatic zones in Odisha with hot and humid climate. Clinical signs and gross lesions as observed among the animals were indicative of Peste des petits ruminants (PPR). There was nearly 90% morbidity and 42.22% mortality. Higher mortality was recorded among the weaners (~ 63%) followed by kids (~ 42%). Blood examination revealed anemia with significantly (p ≤0.05) decrease in total erythrocyte counts (TEC) and packed cell volume (PCV) through t-test. Affected animals showed leucocytosis with nutrophillia and lymphopaenia. Statistically significant (p ≤0.05) alterations in various serum biochemical parameters were evident in morbid animals. At necropsy, typical lesions were erosive as well as hemorrhagic lesions in buccal mucosa, abomasums and intestine along with fibrinous bronchopneumonia. Histopathological changes were mostly infiltrations of inflammatory cells, syncytia and presence of intranuclear and /or intracytoplasmic eosinophillic inclusions in epithelial cells, alveolar macrophages, lungs and hepatocytes.
HIGHLIGHTS
• Pathology of PPR in Ganjam breeds of sheep and goats in Odisha.
• Hot humid climate, nomadic pattern of rearing of Ganjam sheep and goats by “Gola community” were incrementing factors for PPR.
