Abstract

This research aimed to examine the effects of fish oil and tomato powder supplementation on egg quality of Mojosari ducks. A total of one hundred and forty Mojosari ducks (consisted of 20 male and 120 female ducks), aged at 40 weeks old, were randomly allotted into 20 flocks (each flock consisted of 1 male and 6 female ducks). Method used was experiment in a Completely Randomized Design with 5 treatments and 4 replications. Dietary treatments used were T 0 : basal diet (control), T 1 : basal diet + 1% FO, T 2 : basal diet + 2% FO, T 3 : basal diet + 1% FO + 1% TP; T 4 : basal diet + 2% FO + 1% TP. Data were analyzed using one-way analysis of variance (ANOVA). Result showed that supplementation of fish oil and tomato powder did not significantly affect (P>0.05) external egg quality (egg shape index, shell surface area, shell thickness and specific gravity). Dietary treatments also had no significant effect (P>0.05) on internal egg quality (albumen volume, yolk volume, albumen index, yolk index and Haugh unit). It is concluded that there was no detrimental effect of fish oil and tomato powder supplementation in Mojosari ducks diet on external and internal egg quality. Keywords: antioxidant, Haugh unit, laying duck, omega-3 fatty acids, poultry.

Highlights

In the last decade, there is a growing interest in the development of functional food
One kind of functional food is omega-3 egg. This egg is developed by adding dietary omega-3 sources into laying-type poultry diet
Fish oil had higher enrichment of long chain omega-3 in the yolk compared to other source of dietary omega-3 such as flaxseed and marine algae [2]

Summary

INTRODUCTION

There is a growing interest in the development of functional food This food is aimed to satisfy hunger and to provide health benefit for consumers. One kind of functional food is omega-3 egg. In the livestock industries, one kind of functional food is omega-3 egg This egg is developed by adding dietary omega-3 sources into laying-type poultry diet. Fish oil is the most common dietary source of omega-3. Fish oil contains omega-3 in the amount of 26.03% [1]. Fish oil had higher enrichment of long chain omega-3 in the yolk compared to other source of dietary omega-3 such as flaxseed and marine algae [2]. Antioxidant addition is required in laying-type poultry diet containing fish oil.
