Abstract

The concentrations of Fe, Zn, Cu and Mn were determined in meat, inner organs, blood and residual carcass in a total of 24 barrows and gilts of 60 kg and 100 kg of live weight, respectively. the finisher diet contained 192 ppm Fe, 113 ppm Zn, 18 ppm Cu and 65 ppm Mn with, as calculated, a great proportion originating from the mineral supplement. During growth, the contents of Fe, Cu and Mn were significantly reduced. No sex differences occurred. In the lean meat of the 100 kg pigs, common values accounting for 1.1 mg Fe, 2.8 mg Zn and 0.05 mg Cu per 100 g were analyzed. The manganese concentration of 0.01 mg per 100 g, however, was considerably lower as the corresponding figure from nutrient tables. In the finishing period, the animals retained per animal and day about 18 mg Fe, 15 mg Zn and 0.2 mg Cu. Mn retention was not significantly different from zero. The low utilization rates calculated from these data can be partly explained by the moderately excessive supply in this fattening period. In order to reduce the trace element load of the soils, a considerably lower tolerance of excessive trace element contents in finisher diets has to be developed.
