<![CDATA[Abstrak. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian prebiotik Immuno Forte dengan level berbeda terhadap berat dan persentase karkas ayam broiler. Penelitian ini dilakukan di Laboratorium Lapangan Peternakan (LLP) Fakultas Pertanian Universitas Syiah Kuala, Banda Aceh, pada tanggal 22 Agustus sampai 19 September 2015. Penelitian ini menggunakan 100 ekor (DOC) ayam broiler CP 707 Strain Arbor Acres produksi PT. Charoen Pokphand. Ransum yang digunakan adalah ransum komersial R511 Hy-provite priode starterdan R512 Bravo priode finisher. Perlakuan yang diberikan terdiri dari : P0 (0 ml Immuno forte/3 l air ), P1 (0,5 ml Immuno forte/3 l air), P2 (1 ml Immuno forte/3 l air), P3 (1.5 ml Immuno forte/3 l air) dan P4 (2 ml Immuno forte/3 l air). Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 4 ulangan. Parameter yang diamati meliputi berat akhir, berat karkas, persentase karkas, berat potongan karkas dan persentase potongan karkas ayam broiler. Hasil penelitian menunjukkan penambahan prebiotik Immuno forte belum memberikan pengaruh positif terhadap berat karkas ayam broiler. Penambahan prebiotik immuno forte dalam air minum berpengaruh nyata terhadap berat sayap, persentase sayap dan berat punggung ayam broiler, namun tidak berpengaruh nyata terhadap berat hidup, berat karkas, persentase karkas, berat dada, persentase dada, berat paha, persentase paha, berat punggung dan persentase punggung ayam broiler umur 28 minggu. Prebiotics Giving Effect Immuno Forte With Different Level of Carcass Weight and Percentage Broiler Chikens Abstract. This study aimed to determine the effect of prebiotics Immuno Forte with different levels of the weight and the percentage of broiler chicken carcasses. This research was conducted at the Laboratory of Animal Husbandry Field (LLP) Faculty of Agriculture, University of Syiah Kuala, Banda Aceh, on August 22 to 19, 2015. This study used 100 individuals (DOC) CP 707 broilers Arbor Acres strain produced by PT. Charoen Pokphand. Rations used was a commercial ration Hy-provite R511 and R512 starter period Bravo period finisher. Treatments consisted of: P0 (0 ml Immuno Forte / 3 l water), P1 (0.5 ml Immuno Forte / 3 l water), P2 (1 ml Immuno Forte / 3 l water), P3 (1.5 ml Immuno Forte / 3 l water) and P4 (2 ml Immuno forte / 3 l water). The design used was completely randomized design (CRD) with 5 treatments and 4 replications. The parameters observed final weight, carcass weight, carcass percentage, pieces of carcass weight and the percentage of broiler chicken carcass pieces. The results showed the addition of prebiotics Immuno Forte has not been a positive influence on broiler chicken carcass weight. The addition of prebiotics immuno forte in drinking water significantly affect the weight of the wing, the percentage of the wings and heavy backs broiler chickens, but did not significantly affect live weight, carcass weight, carcass percentage, heavy chest, the percentage of the chest, heavy thighs, the percentage of thigh, severe back and backs percentage broilers aged 28 weeks]]>
