为确定蛋黄作为蛋鸡着色剂的适宜性，在蛋鸡日粮中添加天然成分和橙皮，同时研究了蛋黄成分对蛋鸡生产性能、蛋的内外品质特性的影响。本试验以万寿菊、橙皮为原料，通过对其营养成分、叶黄素含量的测定和7~12周的饲养试验，研究了万寿菊、橘皮的蛋黄色素利用率和产蛋性能。用橙皮和万寿菊比较了正常饲料和含有叶黄素的饲料的着色力。与对照组相比，添加万寿菊和橘子皮的蛋黄颜色在4、8和12周显著改善。蛋鸡TH日粮中添加万寿菊和橘子皮不会引起蛋的自然品质和外观品质的恶化，对体重、日产蛋量、蛋重和饲料转化率无显著影响。研究期间无鸟类死亡。结果表明，在两种天然成分中，万寿菊的叶黄素含量(156.32 mg/kg DM)明显高于橙皮(83.02 mg/kg DM)，在蛋鸡日粮中添加4%的万寿菊粉，可在12周时产生蛋黄颜色分数11.00接近30 mg/kg的鸡蛋，而添加4%橙皮的蛋黄颜色分数为5.0。此外，在蛋鸡日粮中添加万寿菊和橘子皮对蛋鸡的内外品质和产蛋性能均无不良影响。因此，万寿菊可以更有效地用于蛋黄着色。
The research was conducted with natural ingredients and orange skin in the diet of laying pullets to determine the suitability as pigmenting agents of egg yolk for laying chicken The influence of tes t ingredients on production characteristics of laying pullets, internal and external quality characteristics of eggs were investigated simultaneously. The experiment covered the proximate analysis of marigold, orange skin meal to determine the nutrient concentrations, xanthophylls contents and 7-12 weeks feeding trail to th th investigate the yolk pigment availability of marigold and orange skin as well as laying performance of birds. Orange skin and marigold were used for comparing the pigmenting ability to normal feed containing xanthophylls. Yolk color was improved significantly as compared to control for addition of marigold and orange skin during 4 , 8 and 12 weeks of supplementation. Inclusion of marigold and orange skin in the th th th diet of laying pullets did not cause deterioration in natural and external quality of eggs and there were no significant variations with respect to body weight, hen day egg production egg weight and feed conversion. There was no mortality of birds during study period. The results indicates the conclusion that between two natural ingredients marigold contain more xanthophylls (156.32mg/kg DM) than orange skin (83.02mg/kg DM) and use of 4% marigold meal in the diet of laying pullets is enough to produce eggs with yolk color score 11.00 close to 30 mg synthetic pigment/kg diet at the 12 week of supplementation, whereas the birds that th received 4% orange skin in the diet were able to produce eggs with yolk color score 5.0. Moreover, use of marigold and orange skin in diet of pullet has no detrimental effect on internal and external quality of egg as well as egg production characteristics. So, marigold can be used more efficiently for egg yolk pigmentation.
