Abstract
The present study was carried out with an aim of enriching desi chicken egg with carot- enoid pigment and to improve its colour of consumers' preference. A total of 96 adult Nicobari fowls at the age of 30 weeks were subjected to four dietary treatments consisting of 1 (T-1), 2 (T-2), and 3 (T-3) g marigold dried petal powder per day per hen and control (c). The mean egg production pa- rameters, egg quality characters and reproductive trait were recorded for 120 days. Marigold feeding to Nicobari fowl up to 3 g did not show any adverse effect on the palatability of feed, egg production performance, egg weight, egg mass output, hatchability and feed efficiency. Significant (P<0.05) improvement in the Roch yolk colour score from 4 to 8 reflected the enrichment of caroteinoid pig- ments in egg yolk. Feeding of dried Marigold petals up to 3 g per hen per day as supplemental feed additive for rural poultry could enrich carotenoid pigments in desi eggs and thereby could improve yolk colour of consumer's preference under semi-intensive system of management to meet the grow- ing demand and changing consumers need for enriched poultry production.

Production performance The mean egg production parameters, both internal and external egg quality characteristics and Roch yolk colour score of dietary treatments are shown in table 2, 3 and 4, respectively
Layers fed with marigold recorded comparatively higher egg production, egg weight, egg mass, better feed efficiency and yolk percent; but the differences observed in means were found to be statistically non-significant as compared to control
Summary
Abstract | The present study was carried out with an aim of enriching desi chicken egg with carotenoid pigment and to improve its colour of consumers’ preference. Feeding of dried Marigold petals up to 3 g per hen per day as supplemental feed additive for rural poultry could enrich carotenoid pigments in desi eggs and thereby could improve yolk colour of consumer’s preference under semi-intensive system of management to meet the growing demand and changing consumers need for enriched poultry production. Desi eggs are always of acceptable yolk colour and are comparatively more preferred by consumers Recent past in these Islands, with due concern for housing of rural poultry, backyard free range system is being shifted to rearing of poultry with supplemental feeding inside poultry shelters. Eggs are good source for enrichment with lutein which in turn capable of increasing the concentration of this pigment in human plasma (Lokaewmanee et al, 2010; Mansoori et al, 2008)
