Abstract

The quality of feed is not only determined by the nutrient content and digestibility of the feed or feed ingredients, but also determined by the palatability of the feed. Palatability is one of important factor in the preparation of rations, because palatability affects the amount of feed intake. The purpose of the study was to determine the effect of feed commercial mixed with palm kernel meal (PKM) that was hydrolyzed by sheep rumen liquor enzyme to palatability of feed by measuring total feed consumption and growth responses of seed catfish (Pangasius hypopthalmus Sauvage). The feeds used in the study were commercial feed added hydrolyzed palm kernel meal (PKMe) and unhydrolized palm kernel meal (PKM). The treatments were as follows A). Commercial feed, B). 30% + 70% BKSecommercial feed30% PKMe + 70% commercial feed, C). 40% PKMe + 60% commercial feed, D). 30% PKM + 70% commercial feed, E). 40% PKM+ 60% commercial feed. Ten fishes with wight around 20 g were used in the trial and held in 80 l tanks. A completely randomized experimental design consisted of 1 variable and triplicates were selected. The result of the experiment showed that feed consumption was not significantly different among the treatment. It was showed that the test diet have a good palatability. The result of feed consumption, survival rate and growth responses observation showed that it was not significantly different among the treatments (P>0.05). Result of digestibility analysis showed that diet A and B have digestibility coefficient higher than diet C and D. Based on the evaluation in those parameters it was concluded that palm kernel meal that has been hydrolized by sheep rumen liquor enzyme have a good palatability and can be used as feed for seed catfish (Pangasius hypophthalmus Sauvage) with addition of up to 40% in the feed.
GONADAL DEVELOPMENT AND SPAWNING FREQUENCY OF TILAPIA (Oreochromis niloticus) THAT FEEDED BY VITAMIN E SUPPLEMENTATION [Perkembangan Gonad dan Performa Pemijahan Induk Ikan Nila (Oreochromis Niloticus) yang diberi Pakan dengan Penambahan Vitamin E Suplementasi] Pamungkas, Wahyu; Tahapari, Evi; Darmawan, Jadmiko

Abstract

Vitamin E merupakan salah satu mikronutrien penting yang berpengaruh terhadap performa reproduksi ikan. Penelitian penambahan vitamin E dalam pakan induk ikan nila (Oreochromis niloticus) bertujuan untuk mengetahui pengaruh vitamin E terhadap perkembangan gonad dan performa pemijahan induk ikan nila. Pakan uji yang digunakan adalah pakan formula dengan kadar protein 35% dan lemak 10% ditambahkan vitamin E (tingkat kemurnian 50%) dengan dosis A) 0, B) 75, C) 150, D) 225, E) 300 and F) 375 mg/kg pakan (kontrol). Induk ikan nila umur 6-7 bulan sebanyak 180 ekor dipelihara dalam 6 jaring ukuran 3x3x1,5m yang diletakkan dalam kolam 6000 m2 dengan kedalaman air 80 cm. Masing-masing jaring diisi dengan 20 ekor induk betina dan 10 ekor induk jantan dan dipelihara selama 13 minggu pada bulan September sampai dengan November 2011. Hasil penelitian menunjukkan bahwa penambahan vitamin E pada pakan induk ikan nila memberikan nilai indeks gonad somatik lebih tinggi dibandingkan yang kontrol. Penambahan vitamin E sebanyak 225 mg/kg pakan memberikan nilai persentase induk matang gonad yang tertinggi (80%) dan frekuensi pemijahan yang terbanyak yaitu 22 kali selama masa pemeliharaan 13 minggu. Berdasarkan hasil penelitian yang diperoleh dapat disimpulkan bahwa penambahan vitamin E sebanyak 225 mg/kg pakan dapat meningkatkan perkembangan gonad, jumlah induk betina yang matang gonad, persentase total pemijahan dan frekuensi pemijahan pada induk ikan nila.
