Production of Pigment Enriched Desi Chicken Eggs by Feeding of Tagetes erecta Petals

“…It indicated that the use of marigold up to 3 g could not affect the palatability of layer pullets and therefore feed intake was found to be non-significant. Results on feed consumption agreed well with the results of Ferdaus et al (2008), Lokaewmanee et al (2010), Mansoori et al (2008), Cho et al (2013) and Amar et al (2013) who reported that dietary inclusion of pigment rich herbs did not reduce the consumption of mixed feed.…”

“…Carotenoids from egg yolk are more bio-available compared to spinach or pigment supplements. In a study, where hens fed with diets containing yellow xanthophylls extracted from Tagetes recorded the improvement in Roch yolk Colour Score up to 11.7 (Ferdaus et al, 2008;Karadas et al, 2006;Lokaewmanee et al, 2010). Similarly, Marigold feed additives fed to quails enhanced the enrichment of total carotenoids in quail eggs (Karadas et al, 2006).…”

“…Used marigold and orange skin become useless and just thrown to dustbins. Researchers (Ferdaus et al, 2008;Karadas et al, 2006;Lokaewmanee et al, 2010) reported that marigold petal meal and its residue are good sources of xanthophylls to be used in layer diets as egg yolk pigmenting agents. Moreover, lutein the rich content of marigold is an excellent natural pigment to reduce the macular degeneration and cataracts, major causes for deterioration of sight in elder people (Karadas et al, 2006).…”

“…There is growing demand for carotenoid-enriched products. 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).…”

Genetic variability and inter-relationship of kernel carotenoids among indigenous and exotic maize (Zea maysL.) inbreds

“…Further, inbreds with enhanced lutein and zeaxanthin can be potentially exploited for developing hybrids for poultry industry. Consumers generally prefer yellow-orange egg yolk as compared to off-white yolk (Lokaewmanee et al 2010;Liu et al 2012) and poultry industry often utilize extracts from petals of marigold flower containing high xanthophylls like lutein and zeaxanthin as egg colorant in feed, as chicken has a natural ability to deposit these molecules into their egg yolks (Galobart et al 2004;Lokaewmanee et al 2010). Thus, inbreds with high lutein and zeaxanthin identified in the study can be used in developing hybrids specifically for poultry industry, the major consumer of maize production in Asia.…”
