Haematological changes in experimental haemonchosis in Barbari goats

The information on caprine haemonchosis is meagre. Therefore, present study was made to study the haematological changes in experimental Haemonchus co ntortus infection in Barbari goats. The ii male goats of g-g;months age wer e divided in 2 groups A and B having 8 infected and 4 control animals respe ctively. Selected animals were first screened and made free from any endo- and ecto-parasites. These were kept under strict hygienic conditions and pr ovided with clean water and tree tops without any grazing. The animals in g roup A, were administered with 5 000 L3 (H. contortus) orally, while those in group B were kept as uninfected control. Both the groups were bled every week and blood samples were examined for haematological parameters, viz. P CV, Hb and TEC and erythrocytic indexes of MCV, MCH and MCHC were worked ou t. Statistical analysis of the data revealed significant fall of PCV, Hb, a nd TEC in infected goats when compared with control indicating anaemia mark ed by no appreciable change in MCV and thus absence of reticulocytosis. Pat hogenesis of anaemia was attributed to haemorrhage and haemodilution after infection.
