Penambahan Selenoprotein pada Pakan terhadap Pertumbuhan Benih Ikan Nila Oreochromis niloticus

Abstract

Penelitian ini bertujuan mengevaluasi penambahan selenoprotein melalui pakan terhadap pertumbuhan benih ikan nila (Oreochromis niloticus). Terdapat tujuh perlakuan berbeda, yaitu K (pakan tanpa penambahan selenoprotein), A, B, C, D, E, dan F (pakan dengan penambahan selenoprotein berturut-turut sebesar 0,3 mg kgˉ¹, 0,6 mg kgˉ¹, 1,2 mg kgˉ¹, 2,4 mg kgˉ¹, 4,8 mg kgˉ¹, dan 9,6 mg kgˉ¹). Penelitian ini menggunakan rancangan acak lengkap dengan tujuh perlakuan dan tiga ulangan. Benih ikan nila berbobot 3±0,14 g dipelihara selama 42 hari pada akuarium berukuran 90 x 40 x 45 cm3 dengan padat tebar 15 ekor/akuarium. Ikan diberi pakan tiga kali sehari secara at satiation. Hasil penelitian menunjukkan penambahan selenoprotein dibawah 9,6 mg kgˉ¹ dapat meningkatkan kinerja pertumbuhan benih ikan nila dengan dosis terbaik 0,3 mg kgˉ¹ pakan yang menghasilkan pertumbuhan dua kali lebih besar.

This study aimed to evaluate the addition of selenoprotein through feed on the growth of tilapia juvenile (Oreochromis niloticus). There were seven different treatments, namely K (feed without selenoprotein addition), A, B, C, D, E, and F (feed with selenoprotein addition respectively 0,3 mg kgˉ¹, 0,6 mg kgˉ¹, 1,2 mg kgˉ¹, 2,4 mg kgˉ¹, 4,8 mg kgˉ¹, and 9,6 mg kgˉ¹). This study used a completely randomized design with seven treatments and three replications. Tilapia juvenile weighing 3±0,14 g were reared for 42 days in an aquarium measuring 90 x 40 x 45 cm3 with a stocking density of 15 fish/aquarium. Fish were fed three times a day on an at satiation method. The results of this study showed that the addition of selenoprotein below 9,6 mg kgˉ¹ could increase the growth performance of tilapia juvenile with the best dose of 0,3 mg kgˉ¹ of feed which results in two times greater growth.
