ABSTRACT

Ameliorative effects of vitamin E or in combination with selenium on hematological characteristics of growing pigs fed crude oil-contaminated diets were studied. 36 landrace pigs were randomly allotted to their pens and pre-conditioned for one week. Four dietary crude oil diets: Diet 1, diet 2, diet 3 and diet 4 contained 0 gram, 5 grams, 10 grams and 15 grams of crude oil/kg of diet were fed for 4 weeks to 9 pigs/dietary treatment group tagged the toxicological phase. After this phase, the amelioration phase with vitamin E alone or in combination with selenium with 3 replications for each treatment group involving the transition of the animals from the toxicological phase to the amelioration phase for duration of 4 weeks after which blood samples were collected from all pigs for hematological analyses. Results showed that vitamin E alone ameliorated the toxic effects of crude oil ingestion on the hematological parameters of the growing pig as there were no significant (P > 0.05) differences on hematological data of the positive control groups compared with the negative control group for all treatment groups; furthermore, the combination of vitamin E and selenium had no additional benefits on the hematological parameters of the pigs as there were no significant (P > 0.05) differences between the vitamin E and vitamin E + selenium groups, respectively. It was thus concluded that vitamin E alone ameliorated the toxic effects of crude oil ingestion on all the growing pig hematological parameters studied in all the treatment groups.
