Abstract: 
The aim of the present study was to investigate whether high vitamin E supplementation has positive effects on performance and carcass traits in fattening pigs. A 2-factorial experiment including 48 pigs (initial weight: 30 kg) was performed over a period of 3 months. Apart from vitamin E-supplementation (alpha-tocopherol acetate, 20 vs. 200 mg/kg) also the source of dietary fat (soy bean oil vs. beef tallow) was varied.Neither the vitamin E supplementation nor the source of dietary fat influenced performance and carcass traits. Thus, the study shows that high vitamin E supplementation regardless of the dietary fat does not improve results in pig fattening.Supplementation with 200 mg vitamin E increased vitamin E concentrations of muscle and adipose tissue by factor 3 to 4 whereas source of dietary fat did not influence vitamin E concentrations of those tissues. The source of dietary fat influenced the fatty acid composition of lipids from muscle and adipose tissue. Feeding beef tallow caused higher levels of monounsaturated fatty acids but lower levels of polyunsaturated fatty acids than feeding soy bean oil. In contrast, vitamin E concentration of the diet did not influence fatty acid composition of tissues. The results of the present study are discussed with respect to the nutritional aspects of meat.
