ABSTRACT

The contents of amino acids (AAs) in the major tissues of living creatures are currently being actively studied in the world, because AAs are between the most important “biologically active substances” (BAC). These BAC are not only construction elements of the body but also valuable products for animal and human nutrition. The aim was to identify patterns in the AA-content of the hybrid pig blood during feeding and removal from fattening, including correlations both between AAs and with the key “biochemical values of animal blood” (BVAB). The high-performance liquid chromatography method was used to determine the AA-content of the blood of the hybrids (Large White Landrace x Duroc) that is between the key indicators for monitoring of the pig product quality. Statistical processing is performed in Microsoft Excel. The data distribution corresponds to a normal distribution, “correlation coefficients according to the Pearson method” (CCPM). The drawings are in the R program. For the first time, the CCPM of amino acids among themselves and with the BVAB were obtained. These values for all the studied animals are significantly higher after fattening (r=0.60-0.88) than in the initial period of fattening (r = 0.17 – 0.35) The obtained CCPM make it possible to reduce the data array for further search and study of blood parameters to improve the efficiency of fattening. The most promising candidates for this are CCPM between amino acids and proteins as key BVAB.
