Content of manganese in m. Semimembranosus, liver and kidney in commercial pigs produced in Vojvodina

Abstract

The content of total ash and manganese (Mn) was investigated in M. semimembranosus, liver and kidney of sixty-nine pigs from ten different commercial genetic lines, produced in Vojvodina. The differences of content of total ash and Mn between different genetic lines of pigs were not significant (P > 0.05) in the analyzed muscle, liver or kidney tissues. The differences of content of total ash and Mn between all three analyzed tissues were highly significant (P < 0.001). The content of Mn was ranging from 0.018 to 0.038 mg/100 g (0.025 mg/100 g, on average) for muscle tissue, from 0.16 to 0.30 mg/100 g (0.22 mg/100 g, on average) for kidney tissue and from 0.23 to 0.51 mg/100 g (0.35 mg/100 g, on average) for liver tissue. Consumption of 100 g of liver tissue contributes minimally 11.4% (up to 25.7%) of the Reference Daily Intake (RDI) value for Mn.
