The Effect of Using Natural Feed Additive on Egg Production and Quality of Mojosari Duck (Anas plathyrhynchos)

Abstract

The aim of this study was to determine the effect of using natural feed additives on egg production and quality of Mojosari Ducks. The animals used were 81-layer period Mojosari ducks 145 days old with an average egg weight 67.55 g and a coefficient diversity 8.98%. Each bird placed in experimental cages 2.25 x 2.25 m. Each plot (experimental unit) placed 3 ducks. The research treatment is adding feed additives (UB Feed) which are composed of natural ingredients, include amino acids, multivitamins, balanced micro minerals, acidifiers, probiotics, and phytobiotics. Research treatment was P1 (100% commercial complete feed), P2 (100% mixed feed), and P3 (100% mixed feed + 0.4% feed additive UB Feed). The research variables were egg production (percentage), cholesterol content (mg/100 mg) and protein content of egg yolk (g/100 g), and protein content of albumin (g/100 g). Based on the research results, the addition of natural feed additives had a very significant effect (P<0.01) on the egg production and quality of Mojosari duck eggs. The addition of natural additive feeds in feed increased egg production, yellow protein content and egg albumin and reduced cholesterol content of egg yolk.
