The results indicated that all egg types had normal appearance with size indexes of 1.24-1.38. The Haugh Units was arround 28.7-67.3 and yolk color score was arround 5.0-13.3. Based on those results, the zerro week marketed eggs (Group I) clasified as A quality and the one week marketed eggs (Group II) were B quality. The data on chemical analyses indicated that the omega-3 fatty acid content was significantly the highest (p<0.05) in Omega-3 egg, while the cholesterol content was 'similar in all types of eggs. The easiest way to judge the quality are from the shape and size of the eggs. Those have to be in normal shape and uniform size. While the claimed on low cholesterol content is not proven.
