- Abstract
To identify the element composition of yolk and white in pasture-raised (PRE) versus hall-raised eggs (HRE), we conducted this investigational study on eggs collected from local raisers and retail stores in Al-Diwaniyah city, Iraq. For such reason, 10 PREs and 10 HREs were subjected to spectrophotometer to detect the amounts of As, Pb, Cd, Zn and Cu in the yolk and white contents. The results of our study recognized that PRE yolk and white have significant (p≥0.05) lower amounts of As, Pb and Cd when compared to those contents from HRE. Interestingly, the amounts of Zn and Cu in yolk and white contents from PRE were significantly (p ≥ 0.05) higher than that from HRE. When the amounts of As, Pb, Cd, Zn and Cu in yolk and white contents compared to each other in PRE or HRE, the results revealed significantly (p≥0.05) higher amounts of these elements in yolk than that in white contents. These results suggest consuming pasture-raised egg rather than hall-raised egg for better health because it contains high amounts of beneficial elements and low amounts of harmful elements. The results also conclude consuming egg white from hall-raised egg when the pasture-raised egg is not available to minimize the effect of toxic elements that are present in high amounts in yolk of the HRE. These findings also provide useful information to egg-industry officials to take suitable actions to imitate pasture-raised breeding conditions in their industries for better egg quality.
