Abstract

The invention relates to a compound premix for aquatic products. The compound premix is prepared from the following raw materials based on the percentage by mass of air dried substances: 10%-15% of a seaweed organism active extract, 5%-10% of a composite acidifier, 5%-10% of compound probiotics powder and the balance of a carrier. The invention also provides a preparation method. The method comprises the following steps: (1) carrying out superfine grinding on raw materials of the seaweed organism active extract, carrying out ultrasonic-microwave synergistic extraction, filtering, wherein filtrate is taken as an extract liquid, carrying out enzymolysis and fermentation on filter residues, so as to obtain a fermentation liquid, respectively carrying out freeze drying on the extract liquid and the fermentation liquid, and then mixing at the ratio; and (2) carrying out superfine grinding on the carrier, and then evenly mixing the ground carrier with the composite acidifier, the compound probiotics powder and the seaweed organism active extract. According to the premix disclosed by the invention, marine algae resources can be effectively utilized; protease can be secreted; digestive absorption of protein is facilitated; the anti-stress ability and the disease resistance of organisms are enhanced; and the growth speed of aquatic livestock is improved, so that the culture cost is reduced and the culture benefits are significantly improved.

Description

technical field [0001] The invention relates to an aquatic feed additive, in particular to a composite premix for aquatic products and a preparation method thereof. Background technique [0002] Aquatic products are one of the most popular foods, and aquaculture has brought good economic benefits to fish farmers. However, with the deterioration of the breeding environment and the development of diseases such as bacteria, the aquaculture industry has been hit hard in recent years. In particular, problems such as low immunity, slow growth, severe disease, and low survival rate of fish and shrimp have affected the healthy development of the aquaculture industry. Aquafeed is one of the most important means of production in aquaculture (accounting for 50-70% of the total cost). etc. have important influences. [0003] In recent years, with the rapid increase of population and the large reduction of arable land, the shortage of feed materials has become a serious problem affect...
