The aim of this research was to review the application of synbiotics in duck feed towards its gastrointestinal and internal organsâ effectivity. The study was carried out to 60 two-months old drake. The feed given to the research subjects consisted of soybean meal, fishmeal, methionine, lysine (PT. CJeil Jedang Tbk. Indonesia), corn, bran, oil, premix, CaCO3 and synbiotics (Lactobacillus sp. and inulin prebiotics). The ratio of feed was based on isoprotein and isocalorie, with 19% of protein and 2900 kcal/kg of metabolic energy. The research was under a fully randomized in vivo experimental method with 4 treatments and 5 replicates, using 3 drakes each. These treatments were R0: controlled feed, with 0% of synbiotics; R1: feed with 2% of synbiotics; R2: feed with 4% of synbiotics; and R3: feed with 6% of synbiotics. Data obtained were subject to analysis of variance. The results show that the use of synbiotics in feed does not have any significance on the weight and length of duodenum, jejunum, and ileum. It also does not have any significance on the weight of gall, pancreas, gizzard, liver and heart. In conclusion, feed with 6% or less of synbiotics can be used without affecting the physical condition of gastrointestinal (weight and length) and internal organ (weight)

The objectives of the research were to supply nitrogen for protein synthesis of ruminal microbe from slow release urea and to supply post-rumen protein from soybean meal protected with condensed tannin (CT) from crude Leucaena leaves extract. In Experiment 1, slow release urea (SRU) was made by extrusion of cassava waste-urea, tapioca meal-urea and cassava meal-urea. Evaluation of SRU properties was based on residual nitrogen concentration and ruminal fermentation products (total volatile fatty acid and ammonia-nitrogen) in vitro. In Experiment 2, soybean meal protected with CT from crude Leucaena leaves extract as much as 1,68 g tannin/100 g DM soybean meal. SRU that was selected from Experiment 1 was used as the supplement in sheep ration whose protein source was protected with CT. SRU supplement in basal rations was 0, 6.36, 12.75, 19.11% DM. In vitro result in Experiment 1, showed that SRU of cassava waste, tapioca meal and cassava meal were different (P<0,01) on residual nitrogen content, total VFA, ammonia-N, and fermentation time. The optimum SRU obtained from cassava waste by inhibiting nitrogen hydrolysis up to 14 h. In Experiment 2, SRU supplementation of cassava waste on basal ration whose protein source was protected with CT increased dry matter (DM) degradability (P<0,01), total VFA (P<0,01), ammonia-N (P<0,01), and did not affect crude protein (CP) ruminal degradation. Post-ruminal degradability of DM and CP increased (P<0.01) in line with the increasing supplement, and reached the optimum level at 12,75 â€“ 19,11% DM. In conclusion, cassava waste was a potent SRU through extrusion process and could be harnessed as SRU supplement in ration with protein source protected with condensed tannin to improve ruminal microbe protein synthesis.

Salah satu faktor pembatas konsumsi daging ayam broiler adalah kandungan kolesterolnya yang cukup tinggi. Kadar kolesterol dapat diturunkan melalui manipulasi pakan, yaitu suplementasi herbal yang difermentasi dengan probiotik (fermeherbafit) dan dienkapsulasi secara mikroskopis. Penelitian ini bertujuan untuk mengevaluasi efek penggunaan fermeherbafit enkapsulasi dalam pakan terhadap kadar kolesterol darah dan daging ayam broiler. Materi yang digunakan yaitu 80 ekor DOC ayam broiler unsex strain Multi Breeder (MB) 202 Platinum yang dipelihara sampai umur 35 hari. Percobaan dilakukan menggunakan metode eksperimental in vivo dan menggunakan Rancangan Acak Lengkap (RAL). Rancangan penelitian terdiri atas lima perlakuan dan setiap perlakuan diulang sebanyak empat kali dengan masing-masing ulangan terdiri dari empat ekor ayam. Perlakuan terdiri dari R0 = pakan basal/kontrol; R1 = penggunaan 1,5% fermeherbafit non-enkapsulasi, R2 = penggunaan 1,5% fermeherbafit enkapsulasi, R3 = penggunaan 3,0% fermeherbafit enkapsulasi, dan R4 = penggunaan 4,5% fermeherbafit enkapsulasi. Hasil analisis variansi menunjukkan penggunaan fermeherbafit enkapsulasi dalam pakan berpengaruh tidak nyata (P>0,05) terhadap kadar kolesterol darah dan berpengaruh nyata (P<0,05) terhadap kadar kolesterol daging ayam broiler. Uji lanjut Beda Nyata Jujur (BNJ) terhadap kadar kolesterol daging menunjukkan R0 berbeda nyata dengan R3 dan R4. Dapat disimpulkan penggunaan fermeherbafit enkapsulasi sampai level 4,5% dalam pakan ayam broiler menghasilkan rataan kadar kolesterol darah yang relatif sama. Penggunaan fermeherbafit non-enkapsulasi 1,5% menurunkan kadar kolesterol daging sebesar 0,79%, sedangkan penggunaan fermeherbafit enkapsulasi 4,5% menurunkan kadar kolesterol daging sebesar 1,50%.
