Abstract

In organic table egg production, saponified extracts of carotenoids are not allowed to intensify egg yolk colour. Therefore, we investigated the suitability of organically produced marigold flower meal (Tagetes erectus, TE) and spinach (Spinacia oleracea, SO) as carotenoid sources (mixture of 25% TE and 75% SO) to reach values of 9-10 'Roche Yolk Colour Fan' units (RYCF units). Feeding a completely unsupplemented control diet resulted in a yolk colour of 4.7 RYCF units, a total supply of 11.1 g/kg, 14.6 g/kg and 17.5 g/kg of TE and SO as stand-alone carotenoid sources induced a significant increase to 8.0, 8.2 and 8.9 RYCF units. Under 'winter-feeding conditions', i.e. minimal carotenoid supply in the diet, 17.5 g/kg TE and SO resulted in 9.3 ± 0.7 RYCF units. It can be concluded that supplementing TE and SO is suitable to improve the yolk colour in organically produced table eggs.

摘要

在有机鸡蛋生产中，不允许使用皂化类胡萝卜素提取物来加深蛋黄颜色。因此，我们研究了有机金盏花粉（Tagetes erectus，TE）和菠菜（Spinacia oleracea，SO）作为类胡萝卜素来源（TE 和 SO 的混合物，比例为 25%TE 和 75%SO）的适用性，以达到 9-10 '罗氏蛋黄颜色扇区单位（RYCF units）。只投喂完全不添加类胡萝卜素的对照饲料，蛋黄颜色为 4.7 RYCF 单位，单独作为类胡萝卜素来源的 TE 和 SO 的总供应量为 11.1 g/kg、14.6 g/kg 和 17.5 g/kg，可显著提高到 8.0、8.2 和 8.9 RYCF 单位。在“冬季饲养条件”下，即饲料中类胡萝卜素供应最低，17.5 g/kg TE 和 SO 可使蛋黄颜色达到 9.3±0.7 RYCF 单位。因此，可以得出结论，补充 TE 和 SO 适合提高有机生产的鸡蛋的蛋黄颜色。
