Abstract
The average level and variability of copper in the liver of pigs of different breeds were studied. Samples of parenchymal organs from pigs were taken immediately after slaughter and analysed at the analytical centre for collective use of V.S. Sobolev Institute of Geology and Mineralogy of the Siberian Branch of the Russian Academy of Sciences using the method of atomic absorption spectrometry with flame and electrothermal atomisation on the SOLAAR M6 spectrometer (USA) by GOST 26929-94 Raw materials and food products— sample preparation Mineralization to determine the content of toxic elements. A normal distribution of the trait was found only in the Landrace breed (W = 0.94). In pig breeding areas, the content of heavy metals in soil, water and feed was studied, which did not exceed the maximum permissible concentration. The most significant variability of the microelement was observed in the Kemerovo breed, the least - in the Landrace breed. The full copper content was marked in the early ripening meat breed and the minimum in the Landrace breed. A smaller interquartile range about the Kemerovo and early meat breeds characterised the level of copper in the liver of Landrace pigs.
