Feed Digestibility is an important indicator which can be used as a guideline to determine the amount of nutrient and feed that can be absorbed by digestive tract. The objective of the research was to determine the value dry matter digestibility (DMD), organic matter digestibility (OMD), NH3 fermentation level and volatile fatty acid (VFA) fermentation level. The research was conducted on January 2018 in Animal Feed and Nutrition Laboratory of Animal Husbandry and Agriculture Faculty, Diponegoro University Semarang. The research method used was in vitro analysis with complete randomized design with five treatments and four replicates. The data were analyzed with analysis of variance at 95% significant level, followed by Duncan Multiple Range Test. The results showed that the highest score of DMD was T5=56.51±0.33%, T4=56.41±2.11; T3=55.86±0.83; highest score of OMD was T5=62.48±0.39%, T4=61.87±1.60; T3=60.86±1.10, the highest NH3 concentration was T3=6.07±1.55 mM, and the highest VFA concentration was T5=55.25±3.40 mM. Sheep’s local feed-based ration was significantly (P<0.05) influenced in vitro DMD, OMD, NH3 fermentation level and VFA fermentation level
The objective of this research was to determine the potential uses of dry matter in the average daily gain of beef cattle and rice straw carrying capacity as a feed alternative. The research used an analytical survey approach, and the location was chosen via purposive sampling. Data collection consisted of conducting interviews and observations based on a questionnaire; then, the collected data were tabulated and analyzed using descriptive statistics. Spearman’s correlation coefficient was used to determine the relationship between dry matter intake level and average daily gain; simple linear regression analysis was used to measure the effect of dry matter intake level on average daily gain. The results revealed that the average daily gain of beef cattle in North Samarinda, Palaran, Sambutan, and Samarinda Ulu (Indonesia) was 0.44 kg, 0.45 kg, 0.45 kg, and 0.45 kg, respectively. The analysis results of dry matter intake level on average daily gain obtained via the regression equation (Y) were as follows: Ỷ = 0.013 + 0.945X. This indicates that every intake of 0.945 kg of dry matter would yield an average daily gain increase of 0.013 kg. Effective utilization of available abundant feed resources (rice straw) is the key to economic maintenance of cattle; however, it tends to have low nutrition and low digestibility, so it is not given as a single feed because it cannot meet beef cattle’s dietary needs. This research found that rice straw production (each hectare of rice area) was able to supply alternative feed for beef cattle of 2.7 animal units per year.
Penelitian ini bertujuan mengetahui tingkat pendapatan, kelayakan finansial, dan manfaat usaha sapi potong peternakan rakyat di Kecamatan Sebulu, Kabupaten Kutai Kartanegara. Penelitian menggunakan metode survei melalui teknik purposive sampling dalam menentukan daerah penelitian, dengan kriteria memiliki populasi sapi potong. Penentuan responden menggunakan pendekatan snowball sampling (bola salju), melalui proses rujukan berlanjut yang memiliki rantai nilai sampai memenuhi 60 responden, dengan dasar: 1) memiliki sapi potong jantan minimal dua ekor; 2) menjalankan usaha sapi potong selama minimal 2 tahun; dan 3) melaksanakan penjualan sapi potong minimal dua ekor per tahun. Analisis finansial terhadap pendapatan digunakan sebagai dasar perhitungan kelayakan usaha dengan menggunakan kriteria break even point (BEP), benefit-cost ratio (BCR), payback period (PP), net present value (NPV), dan internal rate of return (IRR). Usaha sapi potong peternakan rakyat di Kecamatan Sebulu, Kabupaten Kutai Kartanegara, menghasilkan rata-rata pendapatan mencapai Rp16.889.851 per tahun, dengan jumlah penjualan ±3 ekor. Berdasarkan analisis finansial diketahui bahwa usaha sapi potong peternakan rakyat di Kecamatan Sebulu, Kabupaten Kutai Kartanegara, layak dilaksanakan dengan nilai BEP produksi 3 ekor; BEP harga tiga ekor Rp38.505.461; BCR 1,42; PP 2,37 tahun; NPV(10,65%): Rp15.510.245; NPV(15,65%): Rp14.414.358; dan IRR 71%.
Penelitian ini bertujuan untuk mengetahui pengaruh penambahan karagenan dan transglutaminase terhadap komposisi kimia, kualitas fisik, dan karekteristik organoleptik sosis ayam. Rancangan percobaan yang digunakan dalam penelitian adalan rancangan RAL (Rancangan Acak Lengkap) terdiri dari 4 perlakuan yaitu P0 (sosis dengan penambahan karagenan 3 % dan tanpa penambahan transglutaminase), P1 (sosis + karagenan 3 % + transglutaminase 2 ml), P2 (sosis + karagenan 3 % + transglutaminase 3 ml) dan P3 (sosis + karagenan 3 % + transglutaminase 4 ml) dengan masing-masing perlakuan diulang sebanyak 6 ulangan. Variabel yang diamati komposisi kimia (kadar air, kadar protein, kadar lemak dan kadar abu), kualitas fisik (pH, susut masak dan Daya Ikat Air) dan kualitas organoleptik (warna, aroma, tekstur dan rasa). Data komposisi kimia dan kualitas fisik dianalisis menggunakan ANOVA, dan diuji lanjut menggunakan Least Significant Different (LSD). Data kualitas organoleptik dianalisis menggunakan Uji Sensoris Kruskal dan Wallis. Hasil penelitian menunjukkan sosis daging ayam dengan penambahan karagenan dan transglutaminase pada level yang berbeda mempengaruhi kadar air, kadar protein, dan kadar lemak, kadar abu. Sosis daging ayam dengan penambahan karagenan dan transglutaminase pada level yang berbeda berpengaruh pada nilai pH, susut masak, dan daya ikat air Sosis daging ayam dengan penambahan karagenan dan transglutaminase pada level yang berbeda memberikan pengaruh pada kesukaan panelis pada semua parameter (warna, hedonic aroma, hedonic tekstur, rasa) tetapi tidak mempengaruhi penilaian panelis pada mutu hedoniknya. Penambahan transglutaminase sampai dengan 3 ml menyebabkan terjadinya penurunan kualitas kimia tetapi meningkatkan kesukaan panelis pada parameter rasa.
Utilization of local resource (Neptunia plena L. Benth and Leersia hexandra Swartz) as feed ration for buffalo fattening could make cost efficiency, fulfil primary life needs and production.
