Cadmium level in parenchymatous organs of landrace pigs

Abstract

The results of assessing the concentration of cadmium in the liver, kidneys, lungs, and spleen of Landrace pigs are presented. The studies were conducted on clinically healthy 6-month-old animals raised in a sizeable pig-breeding enterprise in the Altai Territory. The conditions for keeping the animals were standard; standard feeding was used for meat fattening. The level of cadmium in parenchymal organs was determined using inductively coupled plasma atomic emission spectral analysis. Data processing was performed using Microsoft Office Excel, the R programming language, and the RStudio data analysis environment version 2022.07.2+576 (RStudio, PBC). The need to use nonparametric criteria has been established. Considering the average values and medians, the authors formed an increasingly ranked series of cadmium content in organs: lungs < spleen < liver < kidneys, in numerical terms, focusing on the first statistical indicator: 1: 1.1: 2.1: 36.0.
