The study’s relevance is related to developing new methods for increasing pig productivity by balancing metabolic processes in the body. The main objective was to determine changes in saturated fatty acid levels in pigs when using a feed supplement of nanoaquachelates, taking into account individual characteristics of the body. The experimental groups of animals were formed using a pulsometric study, which resulted in three groups of 10 pigs, which were then divided into two groups, control and experimental, with five animals each. The experimental group was given a mixture of nano-compounds of iron in a dose of 3 mg/day and germanium in a dose of 0.01 mg/day. The content of saturated fatty acids was assessed using gas chromatography. The results of the study showed that the blood of pigs in the control group with normotonia had increased levels of saturated fatty acids: myristic (P < 0.01), heptadecanoic (P < 0.05), and behenic (P < 0.01). In the blood of pigs in the experimental group with sympathicotonia, the content of saturated fatty acids decreased: myristic (P < 0.01), pentadecanoic (P < 0.01), heptadecanoic (P < 0.01), and behenic (P < 0.01). In the blood of pigs in the control group with vagotonia, the content of saturated fatty acids increased compared to the experimental group. It was found that fatty acids with the highest proportion in experimental normotonic pigs, such as palmitic acid, were 12.1% lower, and stearic acid was 10.7% lower (P < 0.01). In control pigs with sympathotonics, the palmitic acid content was 15.4% higher (P < 0.01) and stearic acid was 17.8% higher (P < 0.001). In experimental pigs with vagotonia, the palmitic acid content was lower by 14.8% (P < 0.01) and stearic acid by 11.8% (P < 0.001). The results of the study showed a positive effect of the mixture of iron and germanium nanocomposites on the indicators of saturated fatty acid metabolism and the formation of pigs following the individual characteristics of the organism, which improved the accuracy of the data obtained
