Produksi telur itik fungsional kaya asam lemak omega 3 dan omega 6 berimbang, vitamin a dan rendah kolesterol melalui suplemntasi minyak ikan, minyak sawit dan zink organik dalam ransum

Abstract

Tujuan penelitian ini adalah untuk menghasilkan telur itik kaya asam lemak ω-3 dan ω-6 dengan komposisi yang seimbang, meningkatkan produksi telur dan kualitas telur, menurunkan kadar kolesterol telur itik dan meningkatkan kandungan vitamin A telur itik. Penelitian dilakukan selama 9 minggu menggunakan 90 ekor itik magelang berumur 21 minggu. Perlakuan yang diberikan adalah: R0 = ransum tanpa menggunakan minyak sawit, minyak ikan, atau Zn organik dengan imbangan ω-3 : ω-6 = 1 : 5; R1 = ransum dengan imbangan ω-3 : ω-6 = 1 : 1,5 + 200 ppm Zn organic; R2 = ransum dengan imbangan ω-3 : ω-6 = 1 : 3 + 200 ppm Zn organic; R3 = ransum dengan imbangan ω-3 : ω-6 = 1 : 4,6 + 200 ppm Zn organic; R4 = ransum dengan imbangan ω-3 : ω-6 = 1 : 6 + 200 ppm Zn organic; dan R5 = ransum dengan imbangan ω-3 : ω-6 = 1 : 7,5+ 200 ppm Zn organik. Penggunaan asam lemak ω -3 dan ω-6 dengan imbangan 1 : 4,6 ditambah Zn organik 200 ppm (R3) menghasilkan performa produksi yang baik, menurunkan kolesterol dalam kuning telur, meningkatkan kandungan vitamin A dan menghasilkan imbangan ω-3 : ω-6 terbaik sebesar 1: 5,29.

The objective of this study were to yield duck eggs rich in ω 3 and ω 6 in a balance ratio, low cholesterol, high vitamin A, and to increase duck egg production. A total of 90 Magelang ducks of 21 weeks old were randomly divided into 18 experimental units and reared during 9 weeks. The diet treatments were: R0 = diet without palm oil, fish oil or organic Zn with the ratio of ω-3 : ω-6 was 1: 5; R1= diet with the ratio of ω-3 : ω-6 was 1: 1.5 + 200 ppm organic Zn; R2 = diet with the ratio of ω-3 : ω-6 was 1: 3 + 200 ppm organic Zn; R3 = diet with the ratio of ω-3 : ω-6 was 1: 4.5 + 200 ppm organic Zn; R4 = diet with the ratio of ω-3 : ω-6 was 1: 6 + 200 ppm organic Zn; and R5 = diet with the ratio of ω-3 : ω-6 was 1 : 7.5 + 200 ppm organic Zn. The results of this study was that feeding diet contained ω-3 and ω-6 fatty acid with the ratio of 1: 4.6 +200 ppm organic Zn produced the duck eggs with the best ratio of ω-3 : ω -6 in the yolk, high in vitamin A, and low in yolk cholesterol. This treatment also increased duck egg production
