Pengaruh Pemberian Pakan Kadar Protein Berbeda dengan Penambahan Hormon Rgh Terhadap Pertumbuhan dan Kelangsungan Hidup Ikan Nila (Oreochromis Niloticus)

Abstract

Research on the Effect of Feeding Different Protein Levels with the Addition of rGH Hormone on the Growth and Survival of Tilapia (Oreochromis niloticus) was conducted in August-October 2022. The purpose of this study was to determine the effect of feeding A, B and C with different protein content on length gain, weight gain, feed conversion ratio, and survival of tilapia (Oreochromis niloticus), to determine the best dose of rGH hormone and protein content on length gain, weight gain, feed conversion ratio, and survival of tilapia (Oreochromis niloticus), to find out the best feed by administering the hormone rGH to length gain, increase in weight, feed conversion ratio, and survival of tilapia (Oreochromis niloticus). The method used in this study was an experimental method with a factorial Randomized Block Design (RBD) with two factors, namely the first factor was giving hormones with 3 levels, namely rGH 9 mg/kg of feed, 12 mg/kg of feed, and 15 mg/kg of feed from feed A, B, and C. The second factor is giving 3 different feeds 3 repetitions. The second factor was giving 3 different feeds 3 repetitions. The results obtained showed that the treatment effect of the addition of rGH doses and different feed protein levels showed that there was a very significant effect on tilapia weight, had a significant effect on tilapia length growth, and was not significantly different on feed conversion ratio. The addition of the rGH hormone dose is a dose of 15 mg with a protein content of 31%. The best addition of feed to the increase in weight and length increase of tilapia was 31%, to the FCR and survival of tilapia which was 28%
