fatty acid composition at the interbreed level were noted only for m. semimembranosus (p > 0.05, difference is not statistically significant). The lack of statistically significant differences in the composition of fatty acids in different muscles may be due to the insufficient sample size and genetic relatedness of the selected breeds. The largest, statistically significant differences were found in the content of fatty acids in the muscles of different groups, which is associated with the peculiarities of their structure and metabolism. Meat of Large White and Landrace pigs, grown in ZAO “Freedom Farm Bacon” in terms of iodine value met the requirements of processing technology, and the ratio of PUFA/SFA in muscle tissues exceeded the recommended norms by 2 times with overestimated values of the atherogenic index in m. semimembranosus.
