Penelitian ini bertujuan untuk mengetahui pengaruh penggantian gamal dengan kaliandra (Calliandra calothyrsus) pada ransum terhadap degradasi rumen secara in-vitro. Penelitian mengunakan rancangan acaklengkap (RAL) yang terdiri dari lima perlakuan dan tiga kali ulangan sehingga terdapat 15 unit percobaan. Adapun kelima perlakuan tersebut adalah: perlakuan A (ransum basal + 20% gamal), B (ransum basal + 15% gamal + 5% kaliandra), C (ransum basal + 10% gamal + 10% kaliandra ), D (ransum basal + 5% gamal + 15 % kaliandra ), dan E (ransum basal + 20% kaliandra ). Peubah yang diamati adalah: degradasi ransumdalam cairan rumen in-vitro (kecernaan bahan kering [KCBK], kecernaan bahan organik [KCBK]), degradasi ransum dalam pepsin in-vitro (KCBK, KCBO), kadar ammonia, kadar VFA (Vollatyl Fatty Acid) dan pH cairanrumen in-vitro. Hasil penelitian menunjukkan bahwa penggantian daun gamal dengan daun kaliandra sampai tingkat 20% dalam ransum, dapat menurunkan kecernaan bahan kering dan organik dalam rumen, tetapisebaliknya meningkatkan kecernaan bahan kering dan organik dalam pepsin in-vitro. Disamping itu dapat menurunkan kadar N-NH3 dan VFA, tetapi meningkatkan pH cairan rumen in-vitro. Dapat disimpulkan bahwa tanin kaliandra dapat dipakai sebagai agen proteksi dari degradasi mikroorganisme rumen in-vitro di dalam ransum, dan penggunaan kaliandra sampai 20% dalam ransum sebagai protek protein ransum dapatmenghasilkan kecernaan bahan kering dan bahan organik pepsin in-vitro tertinggi.

The research aims to know the efficiency of water utilization in local legumes Centrosema pubescens and Clitoria ternatea with gave different concentration of water. The research was conducted for 12 weeks at the Green House Laboratory of Feeds, Faculty of Animal Science, Udayana University, Denpasar. The experimental design used in this research was completely randomn design (CRD) with split plot pattern. The main plot were the type of local legume, Centrosema pubescens (S) and Clitoria ternatea (C), while sub plot were the concentration of water 100% in field capacity (FC) (K1), 80% FC (K2), 60% FC (K3), 40% FC (K4). So, there were eight treatment combinations that were repeated five times with 40 experimental pots. The observed variables in the research were efficiency of water utilization, growth, plant’s production and characteristic grow of the plants. The research result showed that the local legumes were significant difference (P<0.05) in all variables except water utilization efficiency, plant height, number of leaves, dry weight of stem and root. Treatment of water concentration offered to the plants showed significant difference (P<0.05) on all variables except dry weight of leaves, root and the ratio of dry weight of leaves with stems. It can be concluded that the water level of 40% FC still be able to maintain the growth of local legumes as will as in the water concentration of 60% FC and 80% FC. Water concentration of 100% FC produced the highest yield on growth, production and characteristics grow of local legumes. The concentration water 40% FC gave the highest yield on efficiency of water utilization in local legumes. There was no interaction between the types of local legumes with different concentration of water. Keywords: Centrosema pubescens, Clitoria ternatea, waterconcentration, efficiency of water utilization

Penelitian yang bertujuan untuk mengetahui populasi mikroba dari ransum berbasis limbah pertanian yang diproduksi dengan teknologi fermentasi menggunakan kombinasi isolat unggul 1 dan/atau 2 bakteri kolon sapi bali (K1dan/atau K2) serta sampah organik (S1 dan/atau S2) telah dilaksanakan di Laboratorium Nutrisi dan Makanan Ternak Fakultas Peternakan Universitas Udayana. Penelitian dilaksanakan menggunakan Rancangan Acak Lengkap/RAL 12 perlakuan dan 3 ulangan yang didasarkan pada jenis ransum yang diproduksi. Hasil penelitian menunjukkan bahwa bakteri ransum yang diproduksi dengan teknologi fermentasi menggunakan inokulan yang diproduksi dengan kombinasi isolat unggul asal isi kolon sapi bali dengan sampah organik dengan kode RBS12;RBK12;RBS1K1;RBS1K2;RBS2K1; RBS2K2; RBS12K1;RBS12K2;RBS1K12; RBS2K12 dan RBS12K12 mempunyai populasi total bakteri, bakteri lignoselulolitik, dan bakteri asam yang lebih tinggi dan berbeda nyata (P<0,05) dibandingkan dengan ransum yang diproduksi tanpa proses fermentasi (RB0) namun terhadap populasi total fungi, dan fungi selulolitik, fermentasi ransum menggunakan inokulan dengan isolat bakteri unggul asal kolon sapi bali dan sampah organik mempunyai populasi yang berbeda tidak nyata (P>0,05). Berdasarkan hasil penelitian dapat disimpulkan bahwa produksi ransum berbasis limbah pertanian dengan teknologi fermentasi menggunakan kombinasi isolat bakteri unggul 1 dan 2 asal limbah kolon sapi bali serta sampah organik mampu menghasilkan ransum dengan populasi total, bakteri lignoselulolitik,dan bakteri asam laktat yang lebih tinggi.

This study aims to determine the growth and yield of Indigofera zollingeriana plants fertilized with limousin cow manure at different dosage. This research was carried out in the Sesetan Laboratory Greenhouse, Faculty of Animal Husbandry, Udayana University, starting from February to April 2021. The experimental design used in this study was a completely randomized design (CRD) with five treatments and six replications. The five treatments were dosage of 0 tons ha-1 (D0), 10 tons ha-1 (D10), 20 tons ha-1 (D20), 30 tons ha-1 (D30), and 40 tons ha-1 (D40). The variables observed in the study were growth variables, production variables, and growth characteristics variables. The results showed that the application of limousin cow manure fertilizer could increase the total dry weight variable for Indigofera zollingeriana plants but did not have an effect on other variables. The conclusion of this study was that the yeilds of Indigofera zollingeriana was increased by giving dosage of limousin cow manure fertilizer. The application of limousine cow manure fertilizer at the level of 20 tons ha-1 gave the best results. Key words: Growth, Indigofera zollingeriana, limousin cow manure fertilizer, yield

This study aims to determine the physical and chemical quality of rice straw silage made by the addition of Balinese cattle rumen fluid. The study was conducted in Banjar Buda Manis, Sidemen Village, Sidemen District, Karangasem Regency. Silage analysis was carried out at the Animal Nutrition and Food Laboratory, Faculty of Animal Husbandry, Udayana University. The design in the study was complete random concoction with four treatments and four replications. Treatment A (rice straw silage without rumen fluid) "control", B (rice silage straw with additional sterile rumen fluid 50 ml / kg straw), C (silage rice straw with additional fresh rumen liquid 25 ml / kg and sterile rumen fluid 25 ml / kg of straw) and D (rice straw silage with added fresh rumen liquid 50 ml / kg straw). The variables observed were physical quality including pH, fungi, color, aroma, and silage texture, while chemical qualities were: dry matter (DM), organic matter (OM), crude fat (CF), crude fiber (CF’), crude protein (CP), and ash. The results showed, in addition to the PK and SK variables showed a non-significant effect (P> 0.05). The silage CP levels in D treatment were significantly higher than treatments A, B, and C respectively at 11.12, 8.88 and 1.27%, and CF’ levels of D treatment were significantly lower than treatments A, B, and C is 22.06, 13.64 and 8.46%, respectively. The results of this study can be concluded that rice straw silage added with rumen fluid of 50 ml / kg can reduce SK content and increase PK content, while physical quality shows differences which is not real.
