Nutritional composition of chicken (Gallus gallus,Gallus domesticus) and duck (Anasplatyrhynchos) egg powder

Abstract

The study aimed to assess the raw weight and nutrient composition of different parts of chicken (exotic and native) and duck egg powder. Nutrient composition including proximate, mineral and vitamin were analyzed according to AOAC methods. Descriptive statistics and ANOVA were performed and p <0.05 was considered as significant difference. Weight of raw whole egg (p<0.05) and yolk of duck (p<0.05) was found higher than chicken egg. Native chicken’s egg weight was found lower than other two types of eggs but contain almost same proportion of albumen and egg yolk.  Proximate analysis of albumen showed highest protein in native chicken (84.58%), in duck (81.84%) and in exotic chicken (81.43%), respectively. In yolk, duck egg had higher protein (38.5%) as compared to layer chicken egg (36.52%) and native chicken egg (36.16%), consecutively. Native chicken egg albumen possesses higher amount of calcium (2.87mg/gm), magnesium (1.30mg/gm), phosphorus (6.26mg/gm) and potassium (2.48mg/gm) compared to other two types of exotic chicken and duck egg. While, native chicken’s egg yolk contained higher amount of magnesium (0.62mg/mg), phosphorus (17.78mg/mg) and potassium (4.28mg/mg) than other two types of egg.  This study showed higher weight of duck egg than egg of both native and exotic chicken. In dried condition, native chicken’s egg albumen contained high amount of nutrients while in dried yolk of exotic chicken having high amount of nutrients.
