摘要

饲料中α -亚麻酸（ALA）向鸡蛋中DHA的转化效率不高，因此迫切需要能够从富含ALA的饲料中提高蛋黄中二十二碳六烯酸（DHA）富集程度的饲料添加剂。本研究评价了饲粮中添加岩藻黄素对鹌鹑蛋黄中ALA转化为DHA效率的影响。结果表明，在添加0.5 % ALA的饲粮中添加0.02 %岩藻黄质可显著提高DHA转化率51.48 %，提高DHA含量32.82 %，与产蛋高峰期添加1 % ALA时的水平相当。重要的是，岩藻黄素并没有改变磷脂结合DHA的比例。这些结果表明，岩藻黄质作为饲料添加剂，在饲料中添加ALA时，有可能促进鸡蛋中DHA的积累。

Fucoxanthin promotes the conversion efficiency of alpha-linolenic acid in feeding to docosahexaenoic acid in quail egg yolk

The conversion of alpha-linolenic acid (ALA) in feed to DHA in egg is inefficient, so there is a critical need for feed additives that can enhance the enrichment of docosahexaenoic acid (DHA) in egg yolk from ALA-rich feed. The present study evaluated the impact of dietary fucoxanthin on the conversion efficiency of ALA in feed to DHA in quail egg yolk. Results showed that the addition of 0.02 % fucoxanthin to the diet supplemented with 0.5 % ALA significantly enhanced the DHA conversion rate by 51.48 % and increased DHA content by 32.82 %, matching levels observed with 1 % ALA supplementation during the peak laying period. Importantly, fucoxanthin did not alter the proportion of phospholipid-bound DHA. These findings suggest that fucoxanthin, as a feed additive, has the potential to promote the accumulation of DHA in avian eggs when supplemented with ALA in feed.
