To be filled
1. Lutein (from Tagetes erecta)
• Egg Yolk Enrichment: Dietary supplementation with lutein significantly increases its concentration in egg yolks, enhancing yolk pigmentation and nutritional value. In a study, laying hens fed diets supplemented with varying levels of lutein showed a dose-dependent increase in yolk lutein content, with levels plateauing beyond certain supplementation thresholds.

2. Marigold Flower Dry Powder (Tagetes erecta)
• Egg Yolk Pigmentation: Feeding laying hens with diets containing marigold petals and leaves significantly improved egg yolk color. The study found that up to 4% inclusion of orange marigold petals enhanced yolk pigmentation without adversely affecting egg production or bird health.
