Pengaruh Penambahan Asam Lemak Dalam Ransum Terhadap Kualitas Karkas Dan Irisan Komersial Karkas Ternak Potong

An experiment was carried out to investigate the effect of ration containing protected fatty acids on carcass quality and wholesale cuts of livestock. The protected fatty acids was in the form of dried carboxylate salt mixture (DCM). The experiments were assigned to 2x2 factorial model with two feeding treatment P0 (without DCM) and P1 (with DCM) and two animals types J0 (cattle) and J1 (buffaloes). The animals were slaughtered at 315.50±6.96 kg for buffaloes and 289,88 ±6.03 kg for cattle. The results showed that interaction was found between the two factors on striploin. DCM supplementation not significantly all parameters. The buffalo had significantly lower carcass percentage, loin eye area, tenderloin, silverside, fat colour score compared the cattle. It is concluded that DCM supplementation in the ration of buffalo cannot improve the quality of carcass and wholesale cuts

Fermentation Characteristics and Nitrogen Retention of Madura Cattle Fed Complete Rations Containing Soybean Pod and By-Products

This study was aimed to evaluate the effect of complete rations containing soybean pod and soybean by-products (soybean meal and tofu waste) on rumen microbial population, fermentation characteristics, nutrient digestibility, and nitrogen retention of Madura cattle. Twelve Madura cattle of 1.5 years of age were given 4 feeding treatments in triplicates in randomized block design experiment. The treatments included T0 (100% native grass) as a negative control, T1 (concentrate: grass (60:40) as a positive control, T2 (complete ration containing 15% soybean pods), and T3 (complete ration containing 30% soybean pods). The treatments were based on feeding practices commonly applied by farmers in the village. The results showed that the use of concentrate rations or complete rations containing soybean pod and by-product did not affect protozoa population, ammonia concentration, and total VFA production compared to cattle fed 100% native grass. In contrast, the use of concentrate rations or complete rations containing soybean pod and by-products reduced acetate and increased butyrate proportion compared to native grass. The use of a concentrate ration resulted the highest propionate proportion. Methane estimation increased with the use of concentrate ration or complete ration containing 15% soybean pod, but it decreased when the level of soybean pod was increased to 30%. It can be concluded that soybean pod has a potential to be used as a fiber source in beef cattle ration to substitute native grass

Identifikasi Sifat Kualitatif dan Kuantitatif Sapi Rancah

Karakterisasi sifat kualitatif dan kuantitatif diperlukan untuk menggali potensi sapi local sebagai informasi dasar untuk mengembangkan sumber daya genetic sapi tersebut. Penelitian bertujuan untuk mengidentifikasi sifat kualitatif dan kuantitatif sapi Rancah di Kabupaten Ciamis. Sampel yang digunakan adalah 92 ekor sapi Rancah betina, umur > 3 tahun, masing masing 40 ekor dari kecamatan Tambaksari dan 52 ekor dari kecamatan Cijulang. Parameter yang diukur adalah variasi warna bulu, dan ukuran-ukuran tubuh pada kedua daerah penelitian. Data dianalisis secara deskriptif, perbedaan parameter bobot badan dan ukuran tubuh pada kedua populasi penelitian dianalisis dengan Uji T. Hasil penelitian menunjukkan Warna bulu dominan sapi Rancah adalah merah bata. Bobot badan dan ukuran tubuh di Cijulang lebih besar dibandingkan dengan Tambaksari, kecuali panjang dan lebar kepala sama. Bobot badan dan ukuran-ukran tubuh sapi Rancah berada diantara sapi Bali dan PO
