DUCK MEAT OFF-ODOR AS AFFECTED BY DIFFERENT STRAINS AND DIETARY LIPIDS: BAU DAGING ITIK YANG DIPENGARUHI OLEH PERBEDAAN GALUR TERNAK DAN JENIS PAKAN
Get PDFPenelitian ini bertujuan menilai pengaruh perbedaan jenis galur ternak dan lemak pakan terhadap bau off-odor (menyimpang) pada daging ternak itik. Percobaan dilakukan dengan menggunakan rancangan dua faktor pada rancangan acak lengkap. Sebagi faktor pertama adalah jenis galur ternak, yakni galur alabio dan cihateup; sedangkan faktor kedua adalah jenis sumber lemak pakan, yakni lemak sapi, minyak kedelei dan minyak kelapa. Analisis sensori yang dilakukan melibatkan 10-14 orang panelis terlatih untuk menilai kualitas sensori daging dengan menggunakan metode uji ranking, skala dan uji deskriptif. Hasil penelitian memperlihatkan bahwa perbedaan galur ternak dan jenis lemak berpengaruh nyata (P<0,05) terhadap komposisi asam-asam lemak dan intensitas bau off-odor pada daging itik. Itik cihateup memiliki intensitas bau off-odor yang lebih tinggi daripada itik alabio. Analisis deskriptif memperlihatkan bahwa jenis bau off-odor pada daging itik adalah bau tengik, amis, bau lemak, bau jamur, langu, dan bau tanah

Get PDFThis experiment aimed to evaluate the effect of PGF2α and time of injection on the quality and viability of Local ram sperm in Tris dilution at 50C storage temperature. The sperm was collected from four Local rams with artificial vagina, once a week for one month. At the first week, sperm were collected without PGF2α injection; 10 minute after PGF2α injection in second week; 20 minute after PGF2α injection in third week; and 30 minute after PGF2α injection in fourth week. PGF2α with dose of 1,0 ml/head (7,5 mg Luprostiol/ml) were given by intramuscular injection in thigh area. The data were analyzed by Completed Randomized Design. When there were significant differences continued with Duncan’s New Multiple Range Test. The result showed that PGF2α injection significantly (p<0.05) increased the motility sperm and life sperm percentage especially on collected sperm 10 minute after PGF2α injection. Ejaculate volume, pH, sperm concentration, abnormal sperm percentation and sperm viability, showed no significant difference (p>0.05). Based on the result of this study, it was concluded that PGF2α injection 10 minute before sperm collection could improve sperm quantity and quality specifically sperm motility and sperm life percentation

Get PDFTingkat kebuntingan ternak sapi potong di suatu wilayah adalah indikator penting bagi pengelolaan ternak tersebut secara berkelanjutan. Ternak sapi dengan tingkat kebuntingan yang tinggi akan memberikan jaminan bagi tingkat kelahiran yang juga baik, jika ditunjang dengan sistem pemeliharaan yang memadai. Dengan demikian dapat dipastikan bahwa populasi ternak tersevut juga akan terjaga dengan baik. Informasi mengenai tingkat reproduksi ternak sapi potong di Kabupaten Manokwari belum cukup tersedia dan jika sudah adapun masih merupakan penggalan data yang belum terhimpun sebagai data lengkap kabupaten. Penelitian ini bertujuan untuk menyajikan informasi mengenai tingkat reproduksi ternak sapi potong secara khusus tingkat kebuntingan pada empat distrik dengan manajemen pemberian pakan yang berbeda sebagai baseline data dalam pengelolaan pembibitan ternak sapi di Kabupaten Manokwari. Enam ratus dua ekor sapi betina dari empat distrik (Prafi, Oransbari, Ransiki dan Manokwari) di Kabupaten Manokwari dijadikan contoh dalam penelitian ini. Hasil penelitian menunjukkan bahwa ada perbedaan tingkat kebuntingan pada ternak sapi pada sistem pemeliharaan yang berbeda. Sapi betina yang dipelihara dengan sistem dilepas pada suatu areal terbatas (ranch/pastura) dan sistem digembalakan dengan menggunakan tali leher memiliki tingkat kebuntingan yang lebih baik (rata-rata 58%) dibanding ternak sapi yang dipelihara dengan sistem diikat dan diberi hijauan potongan (rata-rata 31%). Kctersediaan pejantan, rasio jantan betina, kesehatan ternak, ketersediaan pakan, pengelolaan padang rumput dan ternak adalah faktor utama yang mempengaruhi tingkat kebuntingan ternak sapi di Kabupaten Manokwari
