本研究的目的是评估鸡蛋中 α-生育酚 (α-Toc) 的积累模式，作为膳食补充 200 mg/kg α-生育酚乙酸酯 (α-TA) 的反应，以及包含不同脂肪酸 (FA) 成分的膳食油是否影响该参数。将 40 只母鸡随机分配到两个处理组中，这些处理组的基础日粮中添加了 200 mg/kg α-TA，并添加了 5% 亚麻籽油 (LO) 或葵花籽油 (SO)。在加入实验日粮后的 0、4、9、14、19 和 50 天测量鸡蛋的 α-生育酚浓度。结果表明，鸡蛋中的α-Toc浓度在饲喂第4天后开始增加，在14天时达到最高水平（168μg/g鸡蛋），此后直到19天下降10%至12%，在50天时获得相似的值（145μg/g鸡蛋）。不同膳食油之间的 α-Toc 在鸡蛋中的沉积模式没有观察到差异。
The objective of the present study was to evaluate the pattern of accumulation of α-tocopherol (α-Toc) in egg as a response to dietary supplementation with 200 mg/kg diet of α-tocopheryl acetate (α-TA) and whether the inclusion of dietary oils with different fatty acid (FA) composition affected this parameter. Forty hens were randomly distributed into two treatments resulting from the supplementation of a basal diet containing 200 mg/kg α-TA with either 5% linseed oil (LO) or sunflower oil (SO). α-Tocopherol concentration of eggs was measured at 0, 4, 9, 14, 19, and 50 d after inclusion of the experimental diets. Results show that α-Toc concentration in the egg increased after the 4th d of feeding, reaching its maximum level at 14 d (168 μg/g egg), after which it decreased 10 to 12% until 19 d, obtaining similar values at 50 d (145 μg/g egg). No differences were observed between dietary oils in the deposition pattern of α-Toc in the egg.
