Suplementasi Vitamin D3 dalam Ransum terhadap Performa Produktivitas Puyuh Petelur (Coturnix coturnix japonica)

Abstract

Penelitian ini bertujuan mengevaluasi pengaruh suplementasi vitamin D3 dalam ransum terhadap performa produktivitas puyuh petelur pada fase produksi yang berbeda. Penelitian dilaksanakan selama enam minggu menggunakan 750 ekor puyuh yang dikelompokkan ke dalam tiga fase produksi. Penelitian menggunakan rancangan acak lengkap (RAL) faktorial 2×3, dengan faktor A berupa jenis pakan (tanpa dan dengan suplementasi vitamin D3) dan faktor B berupa produktivitas (awal produksi: 40-69 hari, puncak produksi: 70-112 hari, akhir produksi: 300-342 hari). Peubah yang diamati meliputi konsumsi pakan, quail day production (QDP), bobot telur, produksi massa telur, konversi pakan, mortalitas, dan income over feed cost (IOFC). Data dianalisis menggunakan analisis ragam (ANOVA). Hasil penelitian menunjukkan tidak terdapat interaksi nyata antara suplementasi vitamin D3 dan fase produktivitas terhadap seluruh peubah yang diamati. Suplementasi vitamin D3 tidak memberikan pengaruh nyata (p<0,05) terhadap seluruh peubah yang diamati. Faktor produktivitas memberikan pengaruh sangat nyata (p<0,01) terhadap konsumsi pakan, quail day production (QDP), bobot telur, produksi massa telur, konversi pakan. Secara umum, suplementasi vitamin D3 membantu menjaga stabilitas performa produksi puyuh, meskipun belum memberikan keuntungan ekonomi yang signifikan.

This study aimed to evaluate the effect of vitamin D3 supplementation in the diet on the productive performance of laying quail at different production phases. The study was conducted over six weeks using 750 quail grouped into three production phases. A completely randomized design (CRD) with a 2×3 factorial arrangement was used, with factor A being diet type (without and with vitamin D3 supplementation) and factor B being productivity phase (early production: 40–69 days, peak production: 70–112 days, and late production: 300–342 days). Variables observed included feed consumption, quail day production (QDP), egg weight, egg mass production, feed conversion ratio, mortality, and income over feed cost (IOFC). Data were analyzed using analysis of variance (ANOVA). The results showed no significant interaction between vitamin D3 supplementation and productivity phase for all observed variables. Vitamin D3 supplementation did not significantly affect (p<0.05) any of the observed variables. The productivity phase factor had a highly significant effect (p<0.01) on feed consumption, quail day production (QDP), egg weight, egg mass production, and feed conversion ratio. Overall, vitamin D3 supplementation helped maintain the stability of quail production performance, although it did not yet provide a significant economic benefit.
