PENGARUH LEVEL PROTEIN YANG BERASAL DARI ALL GRAIN RATION DAN NON ALL GRAIN RATION TEIUIADAP KARKAS DAN LEMAK ABDOMINAL AYAM BROILER AGUS SUMARTONO Penelitian ini. bertujuan untuk mengetahui level protein terbaik dengan menqgunakan sumber protein yang berbeda yalto all grain dan non all grain yang digunakan dalam pakan broiler terhadap peningkatan bobot karkas dan penurunan lemak abdominal. Ternak yang digunakan yaitu ayam broiler umur satu minggu, unsexed, sebanyak 160 ekor, strain Arbor Arcres dengan lama pengamatan lima minggu.Perlakuan yang diberikan dalam penelitian ini terdiri atas lima macam yaitu Rl: ,son all grain ration dengan level protein 22%; R2 all grain ration dengan level protein 19%; K3: non all grain ration dengan level protein 19%; R4: all grain ration dengan level protein 16%; RS: non all grain ration dengan level protein 16%. Rancangan yang digunakan Rancangan Acak Lengkap Pola Searah dengan empat ulangan, setiap unit digunakan delapan ekor ayam untuk melihat perbedaan antar perlakuan dilakokan Uji Kontras Ortoqonal. Variabel yang diamatl. yaitu konsumsi pakan, berat hidup, persentase karkas, dan persentase lemak abdominal. Hasil penilitJ.an menunjukkan bahwa perlakuan memberikan pengaruh yang signifikan (P<0,01) terhadap konsumsi pakan, berat hidup, ctan persentase karkas, sedang per.sentase lemak abdominal tidak signifikan. Dapat disimpulkan bahwa Pakan non all grain pada level protein 19% menghasilkan persentase karkas 61,99% sebaik pakan dengan level protein 22% ( 64, 20%) . Pakan all grain ctapat digunakan pada level protein 19%, karena menghasilkan persentase karkas 66,86% dan persentase lcmak abdominal 1, 73%. Level protein dan sumber protein pakan menghasilkan persentase lemak abdominal yang relatif sama (2,29; 1,73; 3,20; 2,38; dan 3,50%) selama penelitian.

OF PROTEIN LEVEL FROM ALL GRAIN AND NON ALL GRAIN RATION ON BROILER CARCASS AND ABDOMINAL FAT AGUS SUMARTONO 99/128726/l?T/03855 2003 ABST.RACT The experiment was conducted to find out the optimum protein level from different protein sources namely: all grain and non all grain ration on broiler carcass and abdominal fat. One hundred and sixty broiler chickens of J\.rbor Arcres strain, unsexed, one week of age were used during five weeks observation. The ration treatments given in the experiment were Rl: non all grain with 22 % protein level, R2: all grain with 19 % protein level, R3: non all grain with 19 % protein level, R4: all grain with 16 % protein level, RS: non all grain with 16 % protein level. "!'he experiment was designed by Completely Randomized Design of One-Way Classification with four replications and eight broiler chickens each. Orthogonal Contrast test were used to determine the mean at differentee between treatments. The variables observed were feed consumption, liveweight, carcass percentage, and abdominal fat percentage. The result of experiment indicated that experiment had significant effect (P<0.01) on feed consumption, liveweight, carcass percentage, and not significant on abdominal fat percentage. Non all grain ration with 19% protein resulted carcass percentage of 64, 99%, which was similar to ration with 22% protein (64,20%). All grain rat.ion with 19% protein resulted carcass percentage of 66,86% and abdominal fat percentage of 1,73%. Protein level and protein sources showed similar results on abdominal fat percentage (2,29; 1, 73; 3,20; 2,38; end 3,50%).
