Dissertation note The term Designer egg has gained popularity all over the world. Egg which gives some health benefits with the provision of basic nutrients is called designer egg. Lutein a xanthophyll pigment is good for the prevention of age related macular degeneration (AMD).Egg is considered good vehicle for lutein transport as bio-availability of lutein is high through egg. The present study was aimed to produce lutein enriched eggs (designer eggs). Different sources of lutein were used and their effect on production performance and egg quality characteristics was measured. A total number of 432 Hy-line layers categorized into 3 body sizes (Heavy, Medium, Light) were offered 4 different supplementations of lutein (0, free, esterified, free + esterified) replicated 6 times having 6 layers each. Parameters regarding production performance, egg geometry and egg quality were observed.Data were analyzed according to Analysis of Variance (ANOVA) technique through Completely Randomized Design (CRD) using factorial arrangement. Means were compared through Duncan Multiple Range Test (Duncan, 1955) with the help of SAS 9.3. Results of the present study showed significantly higher Haugh unit score (87.17±0.39) in light birds during 3rd week whereas, within lutein sources significantly higher Haugh unit score was observed in layers fed with control diets (85.52±0.48). Significantly (p<0.05) higher yolk pH was observed in layers fed with esterified source of lutein whereas significantly higher (8.26±0.06) albumen pH was observed in birds fed with free source of lutein however, different body sizes could not show their effect on yolk and albumen pH. Significantly higher (62.97±0.22) albumen % was observed during 1st week of study in birds fed with esterified source of lutein whereas body weight categories did not affect the albumen% whereas,
yolk % was affected by different body sizes and lutein sources during 1st week of study. Significantly higher mean value (27.48±0.27) of yolk % was recorded in birds fed with combination of free and esters of lutein whereas higher value of yolk % (27.20±0.23) was observed in medium birds. Shell percentage significantly (p<0.05) affected by different body sizes (10.96±0.13) and lutein sources (11.14±0.18) during 1st week of study whereas shell thickness was significantly (p<0.05) affected by lutein sources (0.35±0.004) during 1st week of study. Means of different sources of lutein had significant (p<0.05) effect on yolk color and the highest mean value (11.63±0.15) was observed in birds fed with free source of lutein. Yolk index was significantly (0.36±0.005) affected by different lutein sources however, body sizes did not affect yolk index. As far as egg geometry was concerned egg surface area and egg volume were found to be significantly highest for heavy birds whereas non-significant differences for egg volume and shape index were observed. However, different lutein sources had no effect on egg geometry parameters. Significantly highest egg weight (62.74±0.23) was observed in heavy layers followed by medium (61.56±0.17) and light (60.63±0.17). However, different body weights (narrow ranges) and lutein sources had non-significant effect on production (%), FCR per dozen, egg mass and FCR per kg egg mass.
