Abstract
Haematological changes due to Trypanosoma evansi infection were studied in 12 Barbari male goats of 6–9 months of age. These were divided in two groups, A and B, consisting of eight infected and four control animals, respectively. The animals were kept in strict hygienic conditions and on a zero grazing schedule. Animals of group A were exposed to 1×10 6 T. evansi subcutaneously. Animals of both the groups were bled weekly and blood samples were examined for different haematological parameters including PCV, Hgb and total RBC count, and erythrocytic indexes of MCV, MCH and MCHC were calculated. Analysis of data revealed significant changes in all these parameters and erythrocytic indexes in infected goats when compared with controls. Observations showed macrocytic anaemia with reticulocytosis in response to early haemolysis.
