Feed Forage and Nutrition Value at Altitudes During the Dry Season in the West Java

Field grass was a source of ruminant forage, especially for rural farmers in the West Java in different altitude. The aim of this study was to determine the potential of grass during the dry season which included the botanical composition analysis and chemical analysis of nutritional value. The study was conducted from September to November 2015. The method used was a survey method, sampling was multistage sampling. The parameters measured in the study included a botanical composition of the forage, biomass production of feed materials on fresh and dry matter, dry material content, an inorganic material included ash, calcium and phosphorus, protein, crude fiber, extract materials without nitrogen, and crude fat. The results showed that the areas in the West Java were drought in September and October, thus resulting in very limited supply of forage and the productivity of the forages was very low. A botanical composition in the highland area was more complete included grass, legumes and weeds than lowland areas and medium altitude. Forage production in highland areas was higher than in lowland areas and medium altitude. Feed plants in the lowlands had a greater fiber content which was forming energy for plants, and lower crude protein when compared to highlan

Komparasi Bobot Potong, Bobot Karkas dan Persentase Karkas pada Sapi Rancah dan Peranakan Ongole Berdasarkan Mutasi pada Gen Leptin

Weight and percentage of the carcass are very important in beef cattle production because they are economic parameters, which describe the number of parts that can be consumed. This study aimed to determine the effect of mutations in R25C and R25H in the Leptin gene on slaughter weight, carcass weight, and carcass percentage of Rancah and Ongole Grade cattle. The secondary data used were 4 genotypes in Rancah cattle, namely CC, CT, CA, and TT respectively, 6, 2, 4, and 2 heads, and 3 genotypes in Ongole Grade cattle, namely CC, CT, and CA, respectively. 4, 2, and 1 head. The data on slaughter weight, carcass weight, and carcass percentage were 14 males of Rancah cattle aged 1.5 – 2.5 years, while data for PO cattle were obtained from 7 males of Ongole Grade 1.5 years old. Parameters measured were slaughter weight, carcass weight, carcass percentage. Data were analyzed descriptively. The results showed that genetic diversity in Rancah and PO cattle due to the R25C and R25H mutations in the Leptin gene was not differences in slaughter weight, carcass weight, and carcass percentage

Evaluation of Glutamine Supplementation in the Diet on the Structure and Function of the Intestine and the Growth Performance of African Catfish, Clarias Gariepinus (Burchell 1822) Juvenile

A triplicate experiment was conducted to evaluate the effect of the diet supplemented with free glutamine (Gln) on intestinal structure and function, as well as the growth performance of African catfish Clarias gariepinus juvenile. The commercial feed was supplemented with Gln of either 0% (control), 0.7%, 1.4% or 2.1%. Fish measuring 2 ± 0.02 cm were stocked in 12 aquariums 50x40x35 cm filled with water at a volume of 50 L with a density of 2,000 fish m-2. Fish were cultured for 30 days and fed on the diets three times a day at satiation. Results showed that the growth rate and biomass of the fish at the end of the experiment had a quadratic response, with the maximum growth achieved at 0.7% Gln treatment. The response pattern of fish growth was in line with the distribution of fish length. Fish in 0.7% Gln treatment had number fish measuring 5-6 cm more than 12% less than other treatments, while fish measuring 7-8 cm were more than other treatments. Higher growth in the 0.7% Gln treatment correlated with longer villi, higher protein retention, and ultimately higher feed efficiency. Increased intake of Gln in the diet also caused an increase in intestinal protease enzyme activity, and accumulation of Gln in the liver, but did not increase the enzymes activity of the liver Superoxidase Dismutase (SOD). It can be concluded that feeding on a diet supplemented with 0.7% Gln can improve the structure and function of the intestine, as well as increase the target size of catfish juvenile production

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

Pengaruh Mutasi pada Gen Leptin terhadap Tebal Lemak Punggung dan Skor Kondisi Tubuh pada Sapi Peranakan Ongole

Mutation on leptin gene affect leptin function as one of the hormones which contribute to body fat deposition. This research aims to determine the effect of R25C and R25H mutations on the leptin gene toward back fat thickness and Body Condition Score (BCS) in Ongole Grade cattle. The study was conducted with a quasi-experimental method, using completely randomized design. The treatments in this study were genotypes differences was, namely CC, TT and AA. This research used sixthteen heads of Ongole Grade Cattle aged ± 2 years, and was reared for 60 days intensively. The feed consisted of forage and concentrate with a ratio of 25: 75, as much as 3% dry matter of body weight and drinking water was given ad libitum. The backfat thickness was estimated using ultrasound performed on 4.5-6.5 MHz frequency, with depth of 8.8-13 cm, BCS was assessed visually by using 1 – 5 score. The backfat thickness data were analyzed by variance component and BCS data was analyzed by Kruskal Wallis. The results showed average of backfat thickness CC, TT and AA genotype were 3.14 mm, 2.9 mm and 3.57 mm, respectively. The body condition score for CC, TT and AA genotype were 3.54, 3.63 and 3.46 respectively. The Mutation of leptin gene on R25C and R25H have not effect to backfat thickness and body condition score in PO cattle
