Abstract:
The present study was envisaged to elucidate the pathomorphological aspects of gastrointestinal tract (GIT) disorders of goats. Study was conducted on 21 (6 healthy goats and 15 diseased goats/kids) and 19 carcasses of goats/kids brought for postmortem to the Department of Veterinary Pathology, LUVAS, Hisar. This study revealed that incidence of GIT disorders was maximum in goats of age group 2-6 months. Major gross lesions noticed were abomasitis, congestion and haemorrhages in intestine and necrotic foci on liver surface alongwith hepatomegaly. Mesenteric lymph nodes were enlarged and oedematous. In case of lungs there was congestion, haemorrhages, consolidation of lungs and pneumonia. Congestion and petechial haemorrhages were the major changes seen in spleen. Heart revealed congestion and hydropericardium. Kidneys revealed congestion and soft kidneys as the major change. Histopathological lesions in abomasum were oedema, congestion and mononuclear cells infiltration in mucosa. In intestine there was desquamation of mucosal epithelium, congestion in mucosa and submucosa along with mononuclear cells infiltration in mucosa, haemorrhages in mucosa, goblet cell hyperplasia and necrosis and replacement of mucosal glands by mononuclear cells. However in one case there was presence of epitheloid cells and Langhan’s type giant cells in mucosa indicating Johne’s disease. Mesenteric lymph nodes revealed congestion and depletion of lymphocyes in germinal center of lymphoid follicle and in one case there was presence of giant cells in cortex of lymph gland. In the liver major change was congestion, degenerative changes in hepatocytes including cloudy swelling, fatty changes, congestion in sinusoids and dilatation of sinusoids leading to atrophy of hepatocytes. There was bile duct hyperplasia along with fibroblast proliferation. Spleen revealed congestion and depletion of lymphocytes in white pulp. Lungs evidenced oedema, congestion, emphysema, serous inflammation and thickening of interlobular septa by fibrinous exudate. Heart revealed congestion, sarcocystosis and mononuclear cell infiltration in myocardium. In kidneys, congestion, focal interstitial nephritis and hyaline degeneration were seen.
