Analysis of nutrient contents of LRI blue shell silky chicken eggs and brown eggs.

The experiment was to determine the nutrient contents of LRI blue shell silky chicken eggs and brown eggs for the reference of nutritional value. Four birds from blue shell silky hens and brown egg hens at 40 weeks of age and fed the same diets for 21 days were taken eggs for determination of eggs content including moisture, crude protein, crude fat, crude ash, calcium, zinc, iron, potassium and lecithin. The results indicated that the contents of blue shell silky chicken eggs and brown eggs were moisture 71.5 vs. 76.1 %, crude protein 12.8 vs. 13.2%, crude fat 12.9 vs. 8.6%, crude ash 1.5 vs. 0.88%, calcium 507 vs. 230 ppm, zinc 20.3 vs. 10.3 ppm, iron 24.6 vs. 18.2 ppm, potassium 15.8 vs. 13.5 ppm and lecithin 3,823 vs. 2,643 mg/100 g, respectively. Silky chicken eggs had higher crude fat, crude ash, calcium, zinc, iron, potassium, selenium and lecithin. Brown eggs had higher moisture and crude protein. There were significant differences.
