Haematological changes associated with crude oil ingestion in experimental rabbits

Abstract

Blood cell profile among experimental rabbits associated with crude oil ingestion were evaluated and 
was significantly (P<0.05) altered. Erythrocytes decreased linearly (P<0.05) indicating an anemic 
condition. The decrease also affected dependable factors such as packed cell volume (PVC) and 
haemoglobin (Hb). Leukocyctes, the main defense cells of the animal decreased linearly (P<0.05) further 
indicating susceptibility of the animal to stress and infection. Granulolytic leukocytes, which include 
neutrophils and eosinophils increased linearly (P<0.05). This increase is a physiological response to 
stress. Lymphocytes, antibody forming leukocytes decreased linearly, indicating a response to stress 
and susceptibility of the animal to infection. Crude oil fraction present in the diet has serious 
consequences on hematological parameters in animals.
