ABSTRACT:The study aimed to investigate the effect of protein level in the complete feed based on fermented banana pseudostem(CFFBP) on in vitro digestibility. The experiment was conducted from May to August 2016. CFFBP was made at the field laboratory of Tribhuwana Tunggadewi University, Malang. Proximate and in vitro digestibility analysis was carried out at the Animal Nutrition Laboratory, the Faculty of Animal Husbandry, Brawijaya University. The experiment used Completely Randomized Design with 3 treatments and 5 replications. The treatments were P 1 CFFBP at protein level 12%; P 2 CFFBP at protein level 14%; P 3 CFFBP at protein level 16%. The results showed that digestibility of dry matter (DMD), digestibility of organic matter (OMD) and Total Digestible Nutrient (TDN) were significantly affected by the treatments (P<0.01). The highest digestibility of DMD, of OMD and TDN was found at CFFBP with protein level 14%. The DMD value were P 1 71.56%, P 2 75.06% and P 3 74.32%. The OMD value were P 1 65.53%, P 2 68.50% and P 3 69,82%. The TDN value were P 1 61.84%, P 2 66.07% and P 3 64.91%. The experiment concluded that the increasing level of protein in the CFFBP could increase DMD, OMD and TDN, and it was related to the availability of protein and energy ratio. The ideal level of protein in this experiment was 14%.
Kualitas daun ketela pohon akan mempengaruhi pertumbuhan ulat sutera, mutu kokon, dan mutu serat yang dihasilkan. Untuk meningkatkan produksi kokon maka dibutuhkan daun ketela pohon yang unggul yang dapat dijadikan pakan ulat sutera. Perbedaan varietas ketela pohon akan menghasilkan daun ketela pohon yang berbeda komposisi dan karakteristiknya. Hal tersebut akan mempengaruhi palatabilitas larva ulat sutera yang akan mempengaruhi performan dan kualitas kokon yang dihasilkan. Tujuan dari penelitian ini yaitu mengetahui jumlah konsumsi daun ketela pohon dan pertumbuhan ulat sutera. Metode penelitian yang digunakan metode eksperimen dengan rancangan percobaan yang digunakan Rancangan Acak Lengkap (RAL) pola searah. Dengan 4 perlakuan yaitu daun jarak (P0), daun ketela varietas faroka (P1), tambak udang (P2), karet (P3). Hasil dari penelitian didapat konsumsi total terdapat perbedaan yang nyata (p<0.05) antara P0 dengan P1 (10,27±0.34 vs 9.04±0.48). Konsumsi Protein Kasar (PK) dan Serat Kasar (SK) terdapat perbedaan yang nyata (p<0.05) antara P1, P2 vs P3 (PK : 2,55±0,13; 2,53±0,24 vs 2,18 a ±0,17 dan SK : 0,98±0,05;1,04±0,09 vs 0,66±0,05). Sedangkan konsumsi Bahan organik (BO) tidak terdapat perbedaan yang nyata. Kesimpulan dari penelitian yang dilakukan penggunaan ketiga jenis daun ketela pohon yang mendekati konsumsi daun Jarak yaitu daun ketela pohon varietas Tambak Udang dan Karet dengan nilai konsumsi total 9.72±0.93 dan 10.04±0.77 g BK/ekor.
ABSTRAKPemanfaatan protein ransum oleh ternak ruminansia untuk meningkatkan produksi tidak dapat optima dengan adanya mikrobia rumen. Keadaan ini menyebabkan menurunnya nilai hayati protein pakan. Untuk itu, perlu dilakukan perlindungan protein pakan. Salah satu yang dilakukan dengan penambahan bahan kimia misalnya formaldehida. Tujuan dari penelitian ini yaitu mengetahui nilai konsumsi, koefisien cerna dan nutrien tercerna protein kasar serta TDN kambing bligon betina yang mendapat suplemen mengandung protein tidak terdegradasi. Metode yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dibagi menjadi 5 kelompok yaitu P1 (Pennisetum purpureum + Gliricidia maculata); P2 (Pennisetum purpureum+suplemen protein); P3 (Pennisetum purpureum+suplemen protein terproteksi 15%); P4 (Pennisetum purpureum+suplemen protein terproteksi 30%); P5 (Pennisetum purpureum+suplemen protein terproteksi 45%). Hasil dari penelitian didapat tidak terdapat perbedaan yang nyata nilai konsumsi, koefisien cerna dan nutrien tercerna protein kasar antar perlakuan. Perbedaan yang nyata (p<0.05) pada nilai koefisen cerna TDN dari yang tertinggi yaitu P 3 : 78,5±2,7%; P 2 : 78,3±2,3%; P 4 : 78,1±2,3%; P 5 : 74,8±2,2%; dan P 1 : 68,7±3,5%. Dari penelitian yang dilakukan dapat disimpulkan penggunaan suplemen yang mengandung protein tidak terdegradasi hingga 45% dalam ransum formulasi tidak berpengaruh terhadap nilai konsumsi, koefisien cerna, dan nutrien tercerna protein kasar. Namun dapat meningkatkan nilai koefisien cerna TDN 78,5% untuk pemberian 15% dalam ransum dan pertambahan bobot badan sebesar 61,3±10,2 gram/hari untuk pemberian 45% dalam ransum.
The preparation process needs to be carried out in the treatment of hatchery waste. The objective of the study was to determine the mineral content and characterization of the eggshell waste after preparation. An experiment was arranged on a completely randomized design (CRD). Preparation treatment consisted of; T1: shell waste watered with distilled water; T2: shell waste soaked in distilled water for 12 h; T3: shell waste soaked in 0.5% NaOH for 720 min; and T4: shell waste boiled at 80°C for 15 min and soaked in 5% H3PO4 for 15 min. The data were analyzed using Analysis of Variance (ANOVA), and if any differences, a Duncan Multiple Range Test (DMRT) post hoc tests were carried out. Composition of proximate and mineral were detected by using X-Ray Fluorescence (XRF). Results indicated that proximate analysis of the dry matter content were T4: 98.98±0.01; T3: 98.58±0.04; T2: 98.75±0.08; and T1: 98.72±0.03. The calcium content of the treatment from the highest was T3: 24.22±0.31; T1: 22.80±0.57; T2: 22.77±0.71; and T4: 21.55±0.46. It may be inferred that the treatment technique had no major impact on the eggshells physical characteristics. However, boiling treatment at 80°C for 15 min and soaking in 5% H3PO4 reduced the eggshell waste's Mg, Si, and Ca content. The addition of 0.5% NaOH immersion did not degrade Mg, Ca, and Si of eggshell waste.
