Haematological Manifestations due to helminthic infections in the domestic fowl, Gallus gallus domesticus Linnaeus 1758 from Darbhanga region (Bihar)

Abstract

The present study focuses on the observation of haematological manifestation in Gallus gallus domesticus due to mixed helminthic infection with cestode parasites (Rallietina and Davainea etc) and nematode parasites (Ascaridia & Hetrakis). Out of 245 host bird examined, 145 were found infected with either singly or mixed infection. For study of effect on blood parameters only 43 (18 male + 25 female) birds were taken. The significant increase was observed in the size of RBC and number of WBC, MCV & MCH and however, reduction in the count of RBC, Hb, PCV in infected Gallus as compared with normal host bird. Thus, the haematological manifestations of the infected host bird Gallus gallus domesticus show that high infection (mixed ones) cause macrocytic anaemia, lymphocytosis etc due to deficiency of related factors.
