Egghance Yellow is a specially formulated feed supplement designed to naturally enhance egg yolk color using pigments derived from marigold. When included in the diet, it increases the concentration of natural pigments in the yolk, resulting in a richer and more vibrant yellow hue.

The pigments are efficiently absorbed and deposited in the egg yolk, with noticeable color improvement occurring within approximately 48 hours of feeding. For optimal yolk coloration, the diet can be balanced with a combination of yellow and red pigments, ensuring consistent and appealing results in egg production. This formulation not only improves visual appeal but also supports overall quality, uniformity, and consumer preference in poultry operations.

Backlashes like suboptimal yolk color, poor skin pigmentation, potential health implications, and reduction in shelf-life of eggs are the observed complications. Impaired liver function can reduce carotenoid conversion and affect yolk pigmentation. Absorption of carotenoids is affected by the health of the digestive tract, especially in cases of GI issues, which can reduce the bioavailability for yolk pigmentation.

A lack of Yellow carotenoids, such as lutein, xanthophyll and zeaxanthin carotenoids can lead to reduced immune function, Insufficient intake of these carotenoids in the diet can result in pale or diminished pigmentation, and poor reproductive health.
