INTISARIPenelitian bertujuan untuk mengetahui konsumsi pakan, pertambahan bobot badan, persentase karkas dan kualitas daging sapi Peranakan Ongole (PO) yang diberi complete feed berbahan dasar tongkol jagung dan suplementasi undegraded protein. Dua belas ekor sapi jantan berumur antara 1,5-2,0 tahun dengan bobot badan rata-rata 272,67+26,84 kg dibagi secara acak menjadi 3 kelompok dengan ulangan 4 ekor. Perlakuan I merupakan ransum dengan pakan basal rumput gajah dan konsentrat BC feed (R-1), perlakuan II merupakan pelet pakan komplit berbahan dasar tongkol jagung (R-2) dan perlakuan III merupakan pelet pakan komplit yang disuplementasi undegraded protein (R-3). Air minum diberikan secara ad libitum. Pada akhir penelitian 3 ekor sapi dari masing-masing kelompok dipotong untuk diketahui persentase karkas, kualitas fisik (pH, warna, daya ikat air (DIA), susut masak dan keempukan) dan kimia daging (kadar air, protein dan lemak). Dilakukan analisis statistik terhadap data yang diperoleh dengan Rancangan Acak Lengkap pola searah dan dilanjutkan dengan uji Duncan's New Multiple Range Test (DMRT). Penggunaan suplementasi undegraded protein (UDP) berpengaruh (P<0,05) pada konsumsi pakan dan pertambahan bobot badan harian (PBBH), tetapi pada feed conversion ratio (FCR) dan persentase karkas menunjukkan perbedaan yang tidak nyata. Kualitas fisik daging menunjukkan bahwa pH R-1 lebih rendah (P<0,05) dari R-2 maupun R-3 (5,32; 5,66 dan 5,62), warna R-1 lebih rendah (P<0,01) dari R-2 maupun R-3 (5,7; 7,2 dan 7,5). DIA pada R-2 dan R-3 lebih tinggi (P<0,05) dari R-1 (16,05; 25,39 dan 24,92%). Dari penelitian ini dapat disimpulkan bahwa penggunaan complete feed dan UDP mampu meningkatkan konsumsi pakan, pertambahan bobot badan harian (PBBH) dan DIA daging pada sapi PO. R-2 and R-3 (5.32, 5.66, and 5.62), the colour of meat for R-1 was lower (P<0.01) than for R-2 and for R-3 (5.7, 7.2, and 7.5). The water-holding capacity was higher (P<0.05) for R-2 and R-3 than for R-1 (16.05, 25.39, and 24.92%). It could be concluded that complete feed and supplementation of undegraded protein improve feed consumption, ADG and water-holding capacity on OC cattle. ABSTRACT This study was conducted to determine nutrient intake, average daily gain, carcass characteristics, and meat quality of Ongole Crossbred (OC) cattle provided with corn cobs as basal diet in complete feed and undegraded protein supplementation. Twelve male cattles of approximately 1.5-2.0 years old with the average liveweight of 272.67+26.84 kg were randomly devided into three groups with four replications, respectively. The first treatment was fed diets with elephant grass as basal diet and BC feed concentrate (R-1), the second treatment was pellet complete feed with corn cobs as basal diet (R-2), and the third treatment was pellet complete feed added with undegraded protein (R-3

The influence of pelagic larval duration (PLD) and egg type dispersal capabilities of 35 demersal and pelagic-spawning tropical fish species is examined in relation to their abundance on the temperate coasts of Japan. The PLDs of pelagic spawners were significantly longer than those of demersal spawners, and a high occurrence of pelagic spawners on the temperate coasts suggests that these fishes are more easily transported to temperate coasts than demersal spawners. For demersal spawners, the common species on the temperate coasts had significantly longer PLDs than the rare species; this suggests that PLD is a major factor influencing the distribution patterns of tropical demersal spawners on temperate coasts. Moreover, a negative correlation between PLD and the abundance of some species of pelagic and demersal spawners suggests the presence of reproductively active fishes in northern subtropical and even in temperate waters.

Our experiment was conducted to study physical quality and chemical composition of meat of Angus (A), Hereford (H), Friesian Holstein (FH), Australian Commercial Cross (ACC) and Murray Grey (MG) cattle breeds grown in a feedlot system. Significant differences were observed among five cattle breeds for cooking loss, tenderness, fatty acid composition, collagen and cholesterol content of meat. However, pH, water‐holding capacity, water, ash, fat and crude protein contents were not different. Cholesterol content of meat of A and FH was lower (P < 0.01) than that of H, ACC and MG. Acidity (pH), cooking loss, shear force, water, ash, crude protein, collagen and cholesterol content of Biceps femoris muscle were higher than those of Longissimus thoracis muscle, but water‐holding capacity and fat content were lower. Unsaturated fatty acid content of Biceps femoris muscle was higher (P < 0.01) than that of Longissimus thoracis. In conclusion, the differences among cattle breeds had a great effect on cooking loss, shear force, collagen, fatty acid composition and cholesterol of meat, but had little effect on water‐holding capacity, pH and proximate composition of meat. The meat of Hereford cattle was the best quality, because of the lowest shear force, cooking loss and collagen. Longissimus thoracis muscle was relatively better in cooking loss, tenderness and collagen content than Biceps femoris muscle.

Penelitian ini bertujuan untuk mengetahui efek lama stimulasi dan tegangan listrik terhadap komposisi kimia, kualitas fisik, dan sensori daging ayam petelur afkir. Penelitian ini menggunakan Rancangan Acak Lengkap pola faktorial 3 x 4 dengan 6 kali ulangan pada setiap kombinasi. Sampel penelitian adalah 72 ekor ayam petelur afkir yang dibagi menjadi 3 kelompok perlakuan dengan lama stimulasi 0, 1, dan 2 menit, dan 4 kelompok perlakuan stimulasi listrik 60, 75, dan 90 volt, dan kontrol dengan jumlah ulangan masing-masing 6 kali. Interaksi lama stimulasi dan tegangan listrik berpengaruh nyata terhadap kualitas fisik daging, yaitu pH, daya ikat air, susut masak, keempukan, dan kadar protein daging. Stimulasi listrik selama dua menit dengan tegangan 90 volt dapat memperbaiki kualitas fisik daging ayam petelur afkir, dibandingkan dengan kombinasi lainnya. Interaksi antara lama stimulasi dan tegangan listrik dapat memperbaiki kualitas sensori daging yaitu keempukan, warna, aroma, dan tekstur daging ayam petelur afkir.

INTISARITujuan dari penelitian ini untuk mengetahui pertumbuhan dan produksi karkas bangsa sapi Peranakan Ongole (PO) dan sapi Simmental Peranakan Ongole (SimPO) yang digemukkan secara feedlot. Sapi jantan PO 6 ekor dan sapi SimPO 6 ekor dengan bobot badan awal PO 315,6±39,46 kg dan SimPO 368,3±17,81 kg digunakan dalam penelitian ini. Sapi dipelihara selama 3 bulan dengan diberi pakan konsentrat, rumput gajah, kulit kedelai, dan ketela pohon. Pada akhir penelitian semua sapi dipotong. Varibel yang diamati adalah konsumsi pakan, kecernaan pakan, pertambahan bobot badan harian (PBBH), konversi pakan, feed cost per gain, kadar urea darah dan kadar glukosa darah, berat potong, berat karkas, persentase karkas, komponen karkas, dan meat-bone ratio. Data yang diperoleh dianalisis dengan t-test. Hasil penelitian menunjukkan bahwa perlakuan berpengaruh nyata pada bobot karkas dan persentase karkas (P<0,05). Perlakuan tidak berpengaruh nyata pada konsumsi pakan, kecernaan pakan, pertambahan bobot badan harian, konversi pakan, feed cost per gain, kadar urea dan glukosa darah, berat potong, komponen karkas, dan meat-bone ratio.
