YOGA FEBI YANDO. Pengaruh Pemberian Probiotik Saccharomyces boulardii Dalam Ransum Terhadap Kecernaan Nutrien Dan Energi Metabolis Itik Petelur. Dibimbing oleh TERA FIT RAYANI. Penggunaan antibiotik sebagai pemacu pertumbuhan dalam jangka panjang telah menimbulkan kekhawatiran terhadap dampak negatifnya, seperti residu antibiotik dalam produk ternak dan gangguan keseimbangan mikrobiota usus pada unggas. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan probiotik Saccharomyces boulardii sebagai feed additive terhadap kecernaan nutrien dan energi metabolis itik petelur. Materi yang digunakan adalah 24 ekor itik alabio betina umur 15 minggu. Penelitian menggunakan Rancangan Acak Lengkap (RAL) terdiri dari empat perlakuan dan lima kali ulangan. Keempat macam perlakuan, yaitu: P0 = Pakan basal, P1 = P0 + probiotik 0,5%, P2 = P0 + probiotik 1%, P3 = P0 + probiotik 1,5%. Peubah yang diukur yaitu kecernaan protein kasar, kecernaan serat kasar, energi metabolis , retensi nitrogen, konsumsi energi, eksresi energi, konsumsi nutrien dan eksresi nutrien. Hasil penelitian menunjukkan bahwa penambahan probiotik berpengaruh nyata (P<0,05) meningkatkan energi metabolis dan ekskresi energi, tetapi tidak berpengaruh nyata (P>0,05) terhadap kecernan protein kasar, serat kasar dan retensi nitrogen. Disimpulkan bahwa dengan penambahan probiotik Saccharomyces boulardii sampai 1% dalam pakan dapat meningkatkan nilai energi metabolis, dan eksresi energi, serta cenderung meningkatkan kecernaan protein kasar.

YOGA FEBI YANDO. Effect of Saccharomyces boulardii Probiotics in Rations on Nutrient Digestibility and Metabolic Energy of Laying Ducks. Mentored by TERA FIT RAYANI. The use of antibiotics as growth promoters in the long term has raised concerns about the negative impacts, such as antibiotic residues in livestock products and disruption of the balance of gut microbiota in poultry. This study aims to determine the effect of the addition of probiotic Saccharomyces boulardii as feed additive on nutrient digestibility and metabolic energy of laying ducks. The material used was 24 ducks alabio female aged 15 weeks. The study used a completely randomized design (CRD) consisting of four treatments and five replications. The four treatments, namely: P0 = basal feed P1 = P0 + 0.5% probiotic, P2 = P0 + 1% probiotic, P3 = P0 + 1.5% probiotic. The variables measured were crude protein digestibility, crude fiber digestibility, metabolic energy, nitrogen retention, energy consumption, energy excretion, nutrient consumption and nutrient excretion. The results showed that the addition of probiotics significantly (P<0.05) increased metabolic energy and energy excretion, but had no significant effect (P>0.05) on crude protein digestibility, crude fiber and nitrogen retention. It was concluded that the addition of probiotic Saccharomyces boulardii up to 1% in feed can increase the value of metabolic energy and energy excretion, and tends to increase crude protein digestibility.
