| Abstract: | This study was carried out to investigate the amelioration effects of vitamin E alone or in combination with selenium on growing pigs that ingested crude oil-contaminated diets. 36 growing landrace pigs weighing on average 15.8 ± 1.4 kg were used and four dietary crude oil-contaminated treatment diets as: diet 1 (control diet) contained 0-gram of crude oil/kg of diet, diet 2 (5 g/kg), diet 3 (10g/kg) and diet 4 (15g/kg), respectively. Diets were fed to the different dietary treatment groups for 3 weeks tagged the toxicological phase with 9 pigs/dietary treatment group. At the end of the toxicological phase, the amelioration phase of incorporation of vitamin E alone or in combination with selenium commenced with 3 replications for each treatment group involving the transition of the animals from the toxicological phase to the amelioration phase for a duration of another 3 weeks. Results revealed that at the low and medium levels of crude oil-contaminated diets, vitamin E alone ameliorated the toxic effects on performance parameters as there were no significant (P > 0.05) effects on performance data compared with the control; whereas similar amelioration was only achieved in the high level of contamination by the combination of vitamin E and selenium as performance parameters were similar (P > 0.05) to the control. It was concluded that vitamin E alone reversed the toxic effects of crude oil ingestion at the low and medium levels of contamination whereas for similar reversal of the toxic effects of crude oil vitamin E needs to be combined with selenium. |
