Effect of feed supplementation on chemical composition of duck eggs in coastal areas of Bangladesh

Abstract

An experiment was conducted to investigate the effect of feed supplementation on chemical composition of Jinding duck’s egg. A total of 180 physically sound eggs were randomly collected in each time at 50% and 75% level of egg production of the ducks. Significant difference was observed for dry matter content of egg albumen of ducks fed on different diets at 50% level of egg production (P<0.01) but no significant difference was recorded for dry matter content of egg yolk at 50% level of egg production (P>0.05). The CP contents of egg albumen and egg yolk differed significantly (P<0.01) at 50% level of egg production but the difference was not significant (P>0.05) for CP content of egg yolk at 75% level of production. There were significant differences (P<0.01) on EE and TA contents of egg albumen and egg yolk at all levels of production. The results of the study demonstrated that the dry matter, as well as crude protein, ether extract and total ash content of eggs on dietary treatment T1(Scavenging + standard ration) was highest compared to the eggs on other treatment groups (T0, T2, T3, T4 and T5).
