Abstract

Increased business development of aquaculture will raise the need of production facilities; one of the examples is the provision of feed. In recent years, the cost requirements for fish feed is quite high, reaching 60% of total operating costs of business. It is due to the reason that all the raw materials are imported. Bran is one component of ingredients in animal feed formulations, both for forage fish, poultry, or large livestock (cattle, horses, pigs, etc.). Furthermore, the needs of the bran will also be limited. This limitation could also be caused by the often inaccurate farmers planting seasons, one of which is caused by climatic conditions which are difficult to predict lately. To overcome it, there should be a breakthrough, namely by making flour from corncobs. The corncob flour is added to the feed formulation: 13,7%; 14,7%; 15,7%; 16,7%; 17,7% and 18,17%. This study aims to obtain necessary corncob flour in feed formulation for the growth of Nila fish. Tests will be evaluated in this study, include: absolute weight gain of tested fish, daily growth rate, feed efficiency, feed conversion, retention of fat and retention of protein. Absolute weight gain, the best feed conversion and efficiency are produced by feed containing corncob flour by 17,7%.
