Embodiment 1

[0037]A composite premix for aquatic products, in terms of air-dried product weight parts, each component is: 15 parts of seaweed bioactive extract, 8 parts of composite acidulant, 10 parts of composite probiotic powder, and 66 parts of carrier.

[0038] Wherein, the seaweed biologically active extract is prepared from a seaweed composition, and the seaweed composition is: 10 parts by weight of Schizochytrium, 10 parts by weight of kelp, 10 parts by weight of Undaria pinnatae, 40 parts by weight of Asparagus, and 20 parts by weight of Enteromorpha 10 parts by weight of seaweed.

[0039] Among them, the composite probiotic powder is calculated according to dry weight parts, and consists of 40 parts of Bacillus subtilis, 30 parts of Lactobacillus acidophilus, 20 parts of Clostridium butyricum, and 10 parts of Streptococcus faecalis.

[0040] Wherein, the composite acidifying agent is calculated according to dry weight parts, and consists of 50 parts of sodium butyrate, 20 parts ...

Embodiment 2

[0052] The breeding test of the compound premix of embodiment 1

[0053] The compound premix of embodiment 1 is added in the prawn feed of monodon according to the ratio of mass percent 1.5% as experimental group, carry out control test with the feed of prawn monodon (control group) that does not add premix, wherein, control group monodon prawn feed, in terms of air-dried weight parts, each component is: 30 parts of fish meal, 23 parts of soybean meal, 3 parts of shrimp shell powder, 10 parts of peanut bran, 4 parts of cotton meal, 4 parts of rapeseed meal, 20 parts of wheat flour 1 part, 1 part of fish oil, 1 part of soybean oil, 1 part of soybean lecithin oil, 1 part of calcium dihydrogen phosphate, and 2 parts of other additives. In the experimental group, 1.5 parts of compound premix was added to the feed of Penaeus monodon in the control group, and 1.5 parts of wheat flour was reduced.

Abstract

The invention relates to a composite premix for aquatic products, which in terms of air-dried mass percentage, comprises 10-15% of seaweed biologically active extract, 5-10% of composite acidulant, 5-10% of composite probiotic bacteria powder, and the rest are carriers . The present invention also provides a preparation method, comprising (1) ultra-finely pulverizing the raw materials of the seaweed bioactive extract, ultrasonic-microwave synergistic extraction and filtering, using the filtrate as an extract, enzymatic hydrolysis and fermentation of the filter residue to obtain a fermentation liquid, The extraction liquid and the fermentation liquid are respectively freeze-dried and mixed in proportion; (2) the carrier is ultra-finely pulverized, and then mixed evenly with the compound acidulant, compound probiotics and seaweed bioactive extract. The premix of the invention can effectively utilize seaweed resources, secrete protease, promote the digestion and absorption of protein, enhance the body's anti-stress and anti-disease ability, and improve the growth rate of aquatic animals, thereby reducing the breeding cost and significantly improving the breeding benefit.

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...
