Differentiation of zinc accumulation in the body of the landras pigs

The presented data pertains to the assessment of zinc levels in the liver, kidneys, lungs, spleen, and myocardium of pigs of the Landras breed. The work was performed on clinically healthy animals, fed in a large pig -breeding complex of the Altai Territory. The technology employed by pigs was three-phase, and the typical conditions were in accordance with GOST 28839–90. The pigs were fed for a duration of 160 days using compound feeds of serial output, accompanied by certificates of conformity, and supplemented with vitamin-mineral premixes that corresponded to precise feeding standards. A zinc level assessment was performed using an atomic emission spectral analysis with inductive-tied plasma. For the processing of primary material, Microsoft Office Excel was utilized, along with the programming language R (version 4.4.1), and RStudio version analysis version 2024.09.0 (2009–2024 Posit Software, PBC). It was established that the distribution of zinc in the liver and kidneys differed from the distribution of the Gauss. In some cases there were emissions, and dispersions that were not homogeneous. Using a median, an increasing ranking range of zinc content in the organs was formed: myocardium < lungs < kidney < spleen < liver, in numerical terms: 1 : 1 : 1 : 1.2 : 1.4 : 2.4 mg/kg. In terms of variability, the smallest uniformity according to the point under consideration is characteristic of the liver. On the basis of the twill painting test, significant differences in the concentration of zinc are established (h = 88,485, df = 4, p < 0,0001). The pawn comparison demonstrated reliable differences in the level of the chemical element in the liver from all other internal organs and myocardial and additionally in pairs: “kidneys-light”, “spleen-lungs”, “kidney-myocardium”, “spleen-myocardium”. The method of agglomeration cluster analysis is allocated such an organ as a liver that has a maximum level of accumulation of the mineral, all other structures are cascaded up to the group with the minimum amount-“light-heart”. Phenotypes of distances between clusters are given. The results are suitable for determining the normative values of zinc content in the liver, kidneys, lungs, spleen and heart muscle of the lands of the Landras grown in Western Siberia.
