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.
本研究旨在评估在蛋鸡饲料混合物中添加大豆（SO）和亚麻籽油（LO）对鸡蛋品质特性、脂肪酸（FA）组成和胆固醇水平的影响。研究材料包括来自食用不含油和添加 2.5% LO 或 SO 的饲料混合物的母鸡所产的鸡蛋。对鸡蛋进行了质量评估。测定了蛋黄中 FA 组成和胆固醇含量。结果表明，补充油分不会导致鸡蛋质量的负面变化。实验组蛋黄中 n3 FA 含量以及所有多不饱和脂肪酸（PUFA）比例均有所增加。这些油对胆固醇水平没有负面影响。因此，分析的饲料添加剂可以作为家禽营养中的一种合适物质安全应用，以增加鸡蛋中的 PUFA。
