The amino acids content was determined in the breast muscle of layers which were kept under experimentally simulated stress conditions and consumed feed mixture (HYD-06-KZ granulated) - original and fortified with vitamins C (Ascorbic acid 2.5 g per head and day), A (Retinol 10 000 IU per head and day), D3 (Cholecalciferol 4 800 IU per head and day) and E (Tocopherol 40 mg per head and day) using the conventional column chromatography method with ion exchangers (AAA T 339). The results indicated that the poultry supplied with vitamins at the appropriate level were able to cope more successfully with the stress (electric current, Narcotan). The values of amino acids in poultry fed with fortified feed increased in comparison with the control. A significant increase (p 0001) was recorded for proline, arginine and glycine. Poultry fed with common feed mixture showed a decrease in the values of amino acids (p 0.05) threonine, glycine, alanine, isoleucine, leucine, lysine and arginine after the exposure to stress factors
