Abstract

ABSTRAK Penelitian ditujukan untuk mengetahui pengaruh penggunaan tepung ampas bir (TAB) terhadap persentase karkas dan lemak abdominal ayam broiler, dilaksanakan bulan Oktober - Desember 2005 di Laboratorium Ilmu Ternak Unggas Fakultas Peternakan, Universitas Diponegoro Semarang. Materi yang digunakan adalah ayam broiler umur 1 hari sebanyak 180 ekor dengan bobot awal 43,78 ± 5,4 g. Kandang yang digunakan adalah 30 petak kandang dengan ukuran 90 x 75 x 50 cm, diisi 6 ekor ayam per petak. Bahan pakan penyusun ransum adalah: jagung kuning, bekatul, bungkil kelapa, “meat bone meal”, pollard, tepung ampas bir, tepung ikan, dan vitamin. Ransum disusun berdasarkan isoprotein dan isoenergi dengan kandungan protein 23% dan energi metabolis 2800 kkal/kg untuk periode “starter” dan kandungan protein 20% dan energi metabolis 2900 kkal/kg periode “finisher”. Rancangan percobaan yang digunakan adalah rancangan acak lengkap (RAL) dengan 6 perlakuan dan 5 ulangan. Perlakuan yang diterapkan adalah sebagai berikut: T0 = ransum kontrol tanpa TAB, T1 = ransum dengan 5% TAB, T2 = ransum dengan 7,5% TAB, T3 = ransum dengan 10% TAB dan T4 = ransum dengan 12,5% TAB dan T5 = ransum dengan 15% TAB. Data yang diperoleh dianalisis ragam dengan uji F, bila terdapat pengaruh perlakuan dilanjutkan dengan uji wilayah ganda Duncan. Parameter yang diamati pertambahan bobot badan, bobot badan akhir, persentase karkas dan persentase lemak abdominal. Hasil penelitian menunjukkan bahwa bobot badan, bobot badan akhir, persentase karkas, potongan karkas dan lemak abdominal tidak dipengaruhi oleh perlakuan. Tetapi kadar lemak karkas dan abdominal menurun dengan pemberian ampas bir dalam ransum. Kesimpulan penelitian adalah TAB dapat digunakan sampai taraf 15% dalam ransum ayam broiler tanpa mempengaruhi persentase karkas. Kata kunci : ayam broiler, TAB, persentase karkas dan lemak abdominal. ABSTRACT This experiment was aimed to study the effect of beer by-product meal on carcass and abdominal fat percentage of broiler chicken, was done at poultry science laboratory, Faculty of Animal Science Dipoengoro University Semarang from October to December 2005. The material used are 180 bird day old chicks (DOC) unsex, with average initial body weight 43,78 ± 5,4 g. Chicks were housed at floor system house divided into 30 pen and each pen was 90 x 75 x 50 cm for 6 birds. The ration consisted of yellow corn, rice brand, coconut meal, meat bone meal, pollard, beer by-product meal, fish meal and vitamin mix. The diet was iso protein – energy with 23% protein and 2.800 kcal/kg for starter and 20% protein and 2.900kcal/kg for finisher. Experimental design was completely rondomized design (CRD) with 6 treatment and 5 596 Karkas dan Lemak Abdominal Ayam Broiler yang Diberi Ampas Bir dalam Ransum Seminar Nasional Kebangkitan Peternakan – Semarang, 20 Mei 2009 replication. The treatment were T0 = diet without BBM; T1 = diet with 5% (BBM); T2 = diet with 7,5% BBM; T3 = diet with 10% BBM; T4 = diet with 12,5% BBm and T5 = diet with 15% BBM. The resulted data was analysed by analysis of variance (ANOVA) with F test to know the effect of treatment, and when there were significant continous to Duncan multiple range test. The result shown that body weight gain, last body weight, carcass percentage, carcass cut portion and abdominal fat did not affected by treatment. But, carcass fat weight is affected by beer by-product meal in the ration. The conclusion resulted from this experiment was the BBM can be used until 15% in the ration of broiler chicken Key words : broiler chicken, BBM, carcass and abdominal fat
