Blood Parameters, Crude Oil, Contamination and Pig.
The effects of graded levels of crude oil-contaminated diets were investigated on haematological parameters in growing pigs. 24 pigs of average body weight (BW) of 8 Â± 1.1 (Mean Â± SD) kg were used in the trial. The animals on arrival at the Animal Wing, Rivers State University were randomly allotted to their experimental pens. There were 6 dietary treatments with varied levels of crude oil contaminations as: 0g (control group), 2g, 4g, 6g, 8g and 10g of crude oil/kg of diet, respectively. There were 4 replications per treatment. The animals were fed at 5% of their BW. Trial lasted for 4 weeks (28d); blood samples were collected from all animal treatment groups and immediately snap frozen. Red blood cell (RBC) counts, haemoglobin (Hb), packed cell volume (PCV) concentrations as well as white blood cell (WBC) counts, including their differentials: neutrophils (NEU), lymphocytes (LYM), eosinophil (EOS) and monocytes (MON) were analyzed. There were no significant (P > 0.05) differences in the RBC, Hb and PCV contents. Furthermore, there were no significant (P > 0.05) differences in the WBC counts as well as their differentials. It was concluded that growing pigs can ingest up to 10g of crude oil/kg of diet without any negative effects on blood constituents of the growing pig.
