Haematobiochemical and Pathological Studies on Amphistomosis in Goats

From May to October, 2024, a total of 200 goats slaughtered at slaughter house, Mhow (Madhya Pradesh) were examined to study the haemato-biochemical, gross and histopathological changes in amphistomosis-affected goats. Following ante-mortem examination blood samples were collected from all the goats for haemato-biochemical examination. Grossly, adult and immature amphistomes were found in rumen and duodenum, respectively. Based on post-mortem presence of amphistomes, animals were grouped as infected (n=41) and non-infected (n=159). Thus, incidence of amphistomosis in goats was 20.5%. Significant (P<0.01) reduction in the mean values of haemoglobin, packed cell volume and total erythrocyte count and significant (P<0.01) increase in total leucocyte count were observed in infected goats as compared to non-infected goats. Differential leucocyte count showed neutrophilia and eosinophilia in infected goats. Compared to non-infected goats, significantly (P<0.01) lower total protein and albumin values were recorded, while significantly (P<0.05) higher alanine aminotransferase level was observed in infected goats. Histopathological changes in rumen revealed congestion, oedema and infiltration of inflammatory cells. The study revealed an incidence of amphistomosis as 20.5% with anaemia, leucocytosis, neutrophilia, eosinophilia, hypoproteinaemia and hepatic damage along with congestion, oedema and infiltration of inflammatory cells in rumen, duodenum and liver.
