This study was aimed to evaluate the physical and chemical quality of the egg. Methodology: Considering the fact a number of 100 eggs was collected from five different commercial poultry farms (20 from each farm). Feed was also collected simultaneously to analysis the proximate components and carotenoid fractions. Physical properties of whole egg (weight and shape index), egg shell (shell % and shell thickness), albumen (height, index and haugh unit) and yolk (height and index) were determined. The visual color was assessed using a Hoffmann La Roche yolk fan (0-15, where higher values indicate a darker color) and three co-ordinates parameters representing the lightness, redness and yellowness of the color was assessed by Minolta Chroma Meter (CR-300, Minolta Camera Co., Ltd. Japan). Egg yolk was analyzed for total carotenoids using iCheck(™) (BioAnalyt GmbH, Germany). The HPLC was used to assess different component of caroenoids, retinol and α-tocopherol. Results: The proximate components of feeds varied from different sources but remained within the range of standard feed for laying hens. The concentration of carotenoid components (lutein, zeaxanthin, β-cryptoxanthin and β-carotene) of different feeds was very low and their sum varied from 1.12-3.02 mg kg1 feed. The physical property, color, total carotenoid, retinol and tochopherol contents of eggs from different farms varied significantly. Conclusion: The micronutrients namely carotenoids (lutein, zeaxanthin, β-cryptoxanthin and β-carotene), retinol and tocopherol in egg yolk were found to be very low in concentration which is a reflection of their content in feed. So, it is clear that the commercial farmers in a developing country do not compromise with the macro nutrients but ignored the micronutrients content in feeds.]]>Deeming, D.C.,20022002pp: 43-53pp: 43-53Bortolotti, G.R., J.J.
