Abstract

The invention discloses a method for preparing a fish feed by utilizing wet-based fermentation raw materials. The method for preparing the fish feed by utilizing the wet-based fermentation raw materials comprises the following steps: stirring 20-35 parts wet-based fermentation raw materials, 40-60 parts of corn and / or a processing product thereof, 10-20 parts of wheat and / or a processing product thereof and 5-15 parts of soybean oil, and carrying out crushing so as to obtain a wet-based fermentation raw material composition; and then, preparing a fish feed by using the wet-based fermentation raw material composition. The method for preparing the fish feed by utilizing the wet-based fermentation raw materials provided by the invention is capable of controlling water content of the whole wet-based fermentation raw material composition at a level suitable for slow and long-term reproduction and growth of probiotics, so that, activity of the probiotics is preserved with mildew growth inhibited; and thus, mildewing rate of a fish feed is slowed down, thereby prolonging storage life of the fish feed. In addition, no high-temperatures drying process is carried out, so that, no large drying equipment, fuel or professionals is required during the production; and no additional drying time is required. Thus, production cost during the production processes is greatly saved with productiontime shortened.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a method for preparing fish feed using wet-based fermentation raw materials and the prepared fish feed. Background technique [0002] Fermented raw materials are high-nutrition feed raw materials made of vegetable raw materials such as rapeseed cake, cotton meal, and rapeseed meal as substrates through microbial fermentation. Due to the removal of undesirable oligosaccharides, antigens, and plant raw materials in the plant raw materials during the preparation process Anti-nutritional factors such as acid and trypsin inhibitor, and rich in nutrients such as organic acids, fermented raw materials are widely used in the preparation of fish feed. At present, the addition method of fermentation raw materials in fish feed is mainly in the form of dry basis. The dry basis fermentation raw materials are low-moisture products whose moisture is reduced from 35-50% to 5-12% after the fe...
