The aim of the work is to find out the influence of essential oils in the diets of sows during farrowing and lactation on the amino acid and mineral composition of milk. The whole milk of sows obtained on the 21st day of lactation was studied, an increase of 9.69% of milk protein in the mass fraction of animals of the experimental group was observed. The amino acid and mineral composition of milk improved. The content of essential amino acids in milk increased: lysine - by 13.18%, alanine - by 13.11%, threonine - by 7.14%, histidine - by 22.22% compared to the control group. In the milk of the research group, an increase in iron content by 13.13%, phosphorus and zinc by 8% and 3.48%, respectively, was noted. The piglets of the research group had a greater increase: on the fifth day of life, the live weight was 5.4% higher; on the 14th day - by 0.4 kg, or by 12.5%, and at weaning (on the 28th day) - by 0.5 kg, or by 6.6% compared to animals of the control group.
