ABSTRACT
A survey of haemoparasitism and associated changes in haemogram of local scavenger chickens (LSC) (Gallus gallus domesticus) was carried out at Maiduguri live bird market. A total of one hundred and twenty-two (122) blood samples were collected during slaughter at the slaughter slab, screened for haemoparasites and examined for changes in haematological parameters using standard procedures. Among the 122 blood samples taken, Haemoproteus spp. had higher prevalence than Plasmodium spp. The female chickens had higher prevalence of haemoparasites than males. Although there were some slight variations in the haemogram (PCV, Hb and RBC) between apparently healthy and haemoparasite infected LSC, the differences were not tatistically significant. The result showed significant (p<0.05) variations in the TWBC counts between apparently healthy male and female; apparently healthy and haemoparasite infected males; apparently healthy male and haemoparasite infected female. Also, there was significant (p<0.05) variation in the heterophil counts between apparently healthy male and female; apparently healthy and haemoparasite infected male; apparently healthy female and haemoparasite infected male; apparently healthy male and haemoparasite infected female. Similarly, there was significant (p<0.05) variation in lymphocytes counts between apparently healthy male and female; apparently healthy female and haemoparasite infected male; apparently healthy female and haemoparasite infected female. In conclusion, the overall prevalence of 45.9% observed for haemoparasite in the study area suggests endemicity of these parasites in local scavenger chickens. The absence of significant differences in haematological profile with the exception of TWBC, heterophils and lymphocytes for apparently healthy and haemoparasite-infected chickens indicate that birds may be harbouring the parasites without causing and/or showing any changes in the haematological profile
