Field grass was a source of ruminant forage, especially for rural farmers in the West Java in different altitude. The aim of this study was to determine the potential of grass during the dry season which included the botanical composition analysis and chemical analysis of nutritional value. The study was conducted from September to November 2015. The method used was a survey method, sampling was multistage sampling. The parameters measured in the study included a botanical composition of the forage, biomass production of feed materials on fresh and dry matter, dry material content, an inorganic material included ash, calcium and phosphorus, protein, crude fiber, extract materials without nitrogen, and crude fat. The results showed that the areas in the West Java were drought in September and October, thus resulting in very limited supply of forage and the productivity of the forages was very low. A botanical composition in the highland area was more complete included grass, legumes and weeds than lowland areas and medium altitude. Forage production in highland areas was higher than in lowland areas and medium altitude. Feed plants in the lowlands had a greater fiber content which was forming energy for plants, and lower crude protein when compared to highland
Fresh feed for cuscus has been carried out, however, the fresh feed has a fast rate of damage, so it is necessary to study the feedthrough further processing in the form of pellet rations which are the result of the formulation of cuscus feed ingredients. As a follow-up, it is necessary to study the physical quality of pellet rations. The formulation of pellet rations was based on the study of preferred level of seven types of cuscus feed (banana, sweet starfruit, matoa leaves, beach ironwood leaves, water spinach leaves, green mustard leaves, and crickets) that are useful as a source of carbohydrates, fiber sources, protein sources of vegetable a protein source of animal. The treatments consisted of three formulations: formulation A based on preference level, formulation B by increasing protein content 10% and formulation C increased protein 20% of requirement. Each formulation was made of two types of pellet diameter, 5 mm and 7 mm, so that pellet rations treatment was obtained. The physical quality test included water content, water activity, pellet and mesh density using analysis of variance, while tests of resistance to friction and resistance to impact were analyzed descriptively. The results showed that the pellet ration with formulation A had better physical quality both with a diameter of 5 mm and 7 mm, but overall from the three formulations concluded that the best 5 mm diameter of a pellet.
Penelitian bertujuan untuk mengkaji kualitas fisik wafer turiang padi (WTP). Turiang merupakan hasil ikutan tanaman padi generasi kedua dengan kandungan nutrisi yang lebih tinggi dibandingkan jerami padi. Rancangan yang digunakan adalah RAL dengan empat perlakuan (P1 : Turiang 100% + rumput lapang 0%; P2 : Turiang 75% + rumput lapang 25%; P3 : Turiang 50 % + rumput lapang 50%; dan P4 : Turiang 25% + rumput lapang 75%) dan enam ulangan. Peubah yang diamati meliputi kualitas fisik WTP dan data yang diperoleh dianalisis statistik dengan ANOVA dan Uji lanjut Duncan. Hasil menunjukkan pembuatan WTP yang dicampur dengan rumput lapang nyata (P<0,05) mempengaruhi kualitas fisik WTP. Rataan KA tertinggi diperoleh perlakuan P2 (10,37%), BJ tertinggi diperoleh perlakuan P4 (0,84), Kerapatan tertinggi diperoleh perlakuan P3 (0,083 g/cm) dan P4 (0,083 g/cm), dan Daya Serap Air tertinggi diperoleh perlakuan P3 (205,24%), sedangkan nilai terendah dari semua peubah yang diamati diperoleh perlakuan P1 dengan nilai berturut-turut KA (P1 9,65% dan P4 9,30%), BJ (0,67), Kerapatan (0,072 g/cm), dan Daya Serap Air (175,52%).
Penelitian bertujuan untuk mengukur efisiensi penggunaan ransum mengandung imbangan protein dan energi (Total Digestible Nutrients) pada domba Garut jantan periode pertumbuhan. Penelitian menggunakan metode eksperimental dengan Rancangan Acak lengkap. Perlakuan penelitian adalah pemberian ransum domba Garut jantan periode pertumbuhan mengandung imbangan protein (12 %, 14 %, dan 16 %) dengan TDN (60 % dan 65 %), setiap perlakuan diulang empat kali. Peubah yang diukur adalah jumlah konsumsi bahan kering ransum, pertambahan bobot badan, dan konversi ransum. Jumlah konsumsi bahan kering tertinggi diperoleh pada pemberian ransum dengan imbangan 12 % protein dan 60 % TDN, yaitu 973,26 g/ekor/hari, pertambahan bobot badan tertinggi diperoleh pada pemberian ransum dengan imbangan 16 % protein dan 65 % TDN, yaitu 114,28 g/ekor/hari, dan konversi ransum terbaik diperoleh pada pemberian ransum dengan imbangan 14 % protein dan 60 % TDN, yaitu 8,32. Hasil penelitian menunjukan bahwa ransum dengan imbangan 12 % -16 % protein dan 60 -65 % TDN memberikan pengaruh terhadap efisiensi penggunaan ransum, dan nilai efisiensi penggunaan ransum paling tinggi pada domba Garut jantan periode pertumbuhan diperoleh pada pemberian ransum dengan imbangan 14 % protein 60 % TDN. Kata Kunci : protein, energi, domba.
