Performan Ayam Broiler Yang Diberi Ransum Yang Mengandung Bungkil Kelapa Yang Difermentasi Ragi Tape Sebagai Pengganti Sebagian Ransum Komersial

The objective of the research was to study effect of using fermented copra meal with ragi tape in ration to replace of commercial feed diets on broiler performance. One hundreds of broiler Lohman strain aged a week were randomly assigned to five dietary treatments. The treatments were consisted of two levels of copra meal without fermentation (BKTF) and two levels of copra meal with fermentation of ragi tape (BKFRT) to replace of part of commercial feed diets (RK) and one of dietary treatment was without copra meal as a control. They were R0 = 100 percent of commercial feed diets as a control (RK); R1 = 10 percent of BKTF + 90 percent of RK; R2 = 20 percent of BKTF + 80 percent of RK; R3 = 10 percent of BKFRT + 90 percent of RK; dan R4 = 20 percent of BKFRT + 80 percent of RK. The chicks were fed for four weeks. At the end of experiment, two broilers from each units were slaughtered to measure carcass weight. Data from completely randomized design were subjected to ANOVA and different among treatments were further analyzed using Tukey test. Parameters of the research were feed consumption, average body weight gain, feed conversion, final body weight and carcass weight. The result of the experiment showed that using of copra meal with or without fermentation used ragi tape in broiler diets to replace commercial feed diets were no significant effect on feed consumption, average body weight gain, final body weight and carcass weight, but they had signifacant effect on feed conversion. Using of copra meal in broiler diets with or without fermentation of ragi tape (BKFRT and BKTF) at level of 20 percent were increase feed conversion. The result concluded that using copra meal in broiler diets with or without fermentation of ragi tape could application at level of 10 percent to replace commercial feed diets, and fermentation of copra meal used of ragi tape had no significant improvement on broiler performance

Hidrolisis Zat Makanan Pakan oleh Enzim Cairan Rumen Sapi Asal Rumah Potong Hewan

The objectives of this experiment were to identify enzymes in rumen liquor of local and imported cattle obtained from abattoir and evaluate the application of enzymes from rumen liquor of cattle against several local feedstuffs for broiler. Enzymes were extracted by combination method of filtration, centrifugation, and precipitation with ammonium sulphate. Doses of enzyme were used at level of 0% (without rumen liquor enzyme), 0.5%, 1.0%, 1.5%, 2.0%, 2.5% and 3.0% (v/w). Optimum precipitation of the enzymes from local and imported cattle were reached at the concentration of 60 and 70 % of ammonium sulphate, respectively. Results showed that the enzymes were able to hydrolyze local feedstuffs and optimum level of enzymes for hydrolysis of rice bran, full fat soybean meal and copra meal was 2.5%, for cassava leaf meal and palm kernel meal was 2.0%, and optimum level of enzymes for broiler diet based on corn-soya was 1.0%. It is concluded that rumen liquor of cattle from abattoir contained cellulase, xylanase, mannanase, amylase, phytase and protease and the enzymes were able to hydrolyze local feedstuffs to improved quality of broiler diet composed of local feedstuffs

Karakteristik Endapan Cairan Rumen Sapi Asal Rumah Potong Hewan Sebagai Feed Supplement

The aims of this experiment were to identify and characterize of sediment product from cattle rumen liquor as a source of amino acids, minerals and vitamins. The sediment were obtained as pellets upon centrifugation of rumen liquor at 10,000 g for 10 minutes for collection of supernatant. The sediment were evaluated for amino acids, minerals and vitamins composition and chararacterized for the pH, solubility of dry matter, specific density, bulk and compacted bulk densities and angle of response. Result of the experiment showed that sediment contained higher minerals: Na, K and Fe compared with the commercial premix, but lower in B-vitamins and amino acids. The composition of mineral Na, K, and Fe from rumen liquor of local cattle was 13.47%, 7.73 % and 14.52 %, while Na, K, and Fe from rumen liquor of imported cattle was 18.40%, 10.25%, and 14.52% respectively. The sediment had pH range from 10.01-10.03, the dry matter solubility was 35.5% up to 39.1%. The sediment from imported cattle had higher specific density, bulk and compacted bulk densities and angle of response than that of local cattle. It is concluded that sediment from cattle rumen liquor contained high Na, K and Fe, low amino acids and B-vitamin, high pH and low solubility

Penggunaan Ekstrak Fermentasi Jahe (Zingiber Officinale) Dalam Air Minum Terhadap Kualitas Karkas Ayam Broiler: the Use of Fermented Ginger (Zingiber Officinale) Extract in the Drinking Water on the Carcass Quality of Broiler

Tujuan penelitian ini adalah mengetahui pengaruh tingkat penggunaan ekstrak fermentasi jahe (Zingiber officinale) dalam air minum terhadap konsumsi air minum,  kualitas karkas (bobot potong, bobot karkas, persentase karkas, kolesterol karkas, bobot lemak abdomen) dan konsumsi ransum ayam broiler. Materi yang digunakan adalah ayam broiler umur satu hari unsex, strain Lohman sebanyak 200 ekor. Rancangan yang digunakan adalah Rancangan Acak Lengkap terdiri 5 perlakuan dan 4 ulangan masing-masing ulangan terdiri dari 10 ekor ayam. Perlakuan terdiri dari P0 = Air minum tanpa penambahan ekstrak fermentasi  jahe (kontrol); P1 = Air minum denagn penambah 2cc ekstrak fermentasi jahe ; P2 = Air minum dengan penambahan  4cc ekstrak fermentasi  jahe; P3 = Air minum dengan penmahan  6cc ekstrak fermentasi  jahe; P4 = Air minum dengan penambahan 8cc ekstrak fermentasi  jahe. Variabel yang diamati adalah konsumsi air minum, kualitas karkas (bobot potong, bobot karkas, persentase karkas, kolesterol karkas, lemak abdomen) dan konsumsi ransum. Hasil penelitian menunjukkan bahwa penggunaan ekstrak fermentas jahe dalam air minum  menunjukkan pengaruh yang  nyata (P<0,05)  terhadap konsumsi ransum dan kualitas karkas (bobot potong, bobot karkas, persentase karkas tetapi penggunaan ekstrak fermentasi  jahe dalam air minum dapat menurunkan kolesterol karkas dan bobot lemak abdomen. Kesimpulan  yang  dapat diambil dari penelitian ini adalah penggunaan ekstrak fermentasi  jahe (Zingiber officinale)  dapat digunakan sampai taraf 8 cc dalam air minum, dapat meningkatkan qualitas karkas dan konsumsi ransum dan dapat menurunkan  kolesterol karkas dan bobot lemak abdominal  ayam broiler
