The study objective was to assess the impact of soybean (SO) and linseed oil (LO) added to feed mixture for laying hens upon the quality characteristics of table eggs, their fatty acid (FA) profile and cholesterol level. The material consisted of eggs from hens fed with a mixture without oil and with the addition of LO or SO in a dose of 2.5%. Eggs were subjected to quality assessment. FA profile and cholesterol content in yolks were determined. The results indicate no negative changes in eggs’ quality caused by supplementation. An increase was observed in the n3 FA content in egg yolk in experimental groups, as well as all PUFA (polyunsaturated fatty acids) proportions. No negative impact of these oils on the level of cholesterol was noted. As a consequence, the analysed feed additives can be safely applied as an appropriate material in poultry nutrition to enrich eggs with PUFA.
