Abstract

Chickens were exposed to aflatoxin sourced from rice substrate.Enzyme immunosorbent assay was used to evaluate the immune response to newcastle disease vaccinations vis a vis the hematological pictures. Results shows a dose dependent reduction in immune titer to newcastle disease.Hematological findings confirms leucopenia,throbocytopenia, with increased PCV and hemoglobin.Also increased is the heterophils which was masked by other lucocytes reduction. This hematological picture and immunosuppression is being linked to increased glucocorticoid in the subjects.
