Penelitian yang bertujuan untuk mengetahui utilisasi nitrogen dan komposisi tubuh kambing peranakan etawah yang diberi pakan hijauan rumput lapangan dengan suplementasi dedak padi, telah dilaksanakan. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) yang terdiri dari 4 perlakuan dan 4 ulangan. Keempat perlakuan tersebut adalah Rumput lapangan ad libitum sebagai perlakuan (A); perlakuan B= perlakuan A + 75 g dedak padi; perlakuan C = perlakuan A + 150 g dedak padi dan perlakuan D= perlakuan A + 225 g dedak padi. Pemberian rumput lapangan 2 kali sehari yaitu pagi pukul 7.00 Wita dan sore pukul 16.00 Wita, sedangkan dedak padi diberikan sekali pada pukul 7.00 Wita. Air minum yang diberikan berasal dari PDAM secara ad libitum. Variabel yang diamati adalah komposisi tubuh, konsentrasi urea darah, konsumsi nitrogen, retensi nitrogen dan utilisasi nitrogen. Hasil penelitian menunjukkan bahwa suplementasi dedak padi dari 75-225 g/ekor/hari pada kambing PE yang diberi pakan hijauan rumput lapangan secara nyata (P<0,05) dapat meningkatkan konsumsi nitrogen, retensi nitrogen, utilisasi nitrogen dan tidak nyata (P>0,05) menurunkan urea darah. Namun suplementasi dedak padi 75 g/e/h belum berpengaruh terhadap air tubuh dan lemak tubuh, tetapi suplementasi dedak padi pada level 150-225 g/e/h dapat menurunkan air tubuh dan meningkatkan lemak tubuh. Suplementasi dedak padi dari 75-225 g/ekor/hari belum berpengaruh nyata terhadap penurunan protein tubuh. Dari hasil penelitian dapat disimpulkan bahwa suplementasi dedak padi dari 75-225 g/ekor/hari dapat meningkatkan utilisasi nitrogen pada kambing peranakan etawah yang diberi pakan hijauan rumput lapangan.

Green bean sprout waste is obtained from its production with the basic ingredients and sellers. This waste product is one of the potential ingredients in broiler chicken ration and a source of vegetable protein. However, the fiber and protein contents of bean sprouts are high, and therefore need to be fermented to improve digestibility and nutritional quality. This research, therefore, aims to determine the nutrient content of broiler chicken rations in the finisher phase containing fermented bean sprouts waste flour by proximate analysis in the laboratory. This study was conducted using a Completely Randomized Design (CRD) with 4 treatments and 3 replications. The treatments consisted of rations without fermented bean sprouts waste flour (TLTF) (P0), 3% TLTF (P1), 6% TLTF (P2), and 9% TLTF (P3). The variables analyzed were crude protein, fiber, and fat of the ration. The results of this study showed that the provision of fermented bean sprouts wastes flour for broiler chicken ration in the finisher phase significantly affected (P <0.05) the variables of protein, fiber, and fat. In conclusion, an increase of crude protein and fiber in broiler chicken rations with 6% TLTF was the closest to the standard requirement in the finisher phase.

The purpose of this study was to determine the effect of fermented cassava peel flour on carcass weights and parts of broiler carcasses. This study used 45 CP-707 broiler strains. The design used was a randomized design complete with 3 replications. This study uses fermented cassava peels mixed in ration with 5 level administration, namely: without fermented cassava skin flour (P0), fermented cassava skin flour 3% (P1), fermented cassava skin flour 6% (P2), fermented cassava skin flour 9 % (P3), and 12% fermented cassava peel flour (P4). The application of fermented cassava peel at 9% level in the 6-week broiler ration did not significantly affect all observed variables, but application at 6% level tended to increase carcass weight, breast weight, thigh weight, and wing weight. The fermentation of cassava peel flour at 12% in the ration had a significant effect in reducing carcass weights and weight of broilers at 6 weeks. The results showed that fermentation of cassava peel flour in rations up to 6% tended to increase carcass weight, chest weight, thigh weight, and swing weight, whereas at 12% had a significant effect in reducing carcass weight and weight of broilers at 6 weeks.

One of the maintenance management of Broilers is the regulation of cage density. In the tropics, cage density affects comfort in a cage, high temperature and humidity are the main causes of stress in chickens. Cages with in apropriate densities have a negative impact on meat production and quality performance. The study aims to identify cage density to the quality of broiler chicken meat. The study used a completely randomized design with 3 treatments, namely density 8, 10 and 12 tails per square meter, each treatment was repeated tree times. The result showed that the difference in cage density in the maintenance of broiler chicken up to the age of fine weeks did not affect meat quality. It is recomended maintenance with a density of 12 tails broiler chicken up to age of 5 weeks can be done without affecting the quality of meat.
