Problems solved by technology

This kind of feed is difficult to meet the nutritional needs of a certain type of sea fish raised. The characteristics of this type of compound feed are high waste, low absorption and utilization rate, heavy pollution, and poor breeding effect, and it is easy to cause slow growth of farmed fish. Weak constitution and poor resistance to disease and stress seriously restrict the development of grouper aquaculture industry. Although there are researches on grouper nutrition in China, the formula nutrition and processing technology are not ideal

Embodiment 1

[0013] The formula of the fish full-price compound feed components in this example is (unit: Kg): fish meal 43; Insect 4, fish oil 3, soybean lecithin 3, DHA 0.6, EPA 0.4, compound mineral salt 1.8, compound enzyme preparation 0.3, compound immune enhancer 0.3, liver strengthening agent 0.3, compound microecological preparation 0.3.

[0014] Its preparation process includes:

[0015] a) First mix fish meal, fermented bean curd, squid meal, krill meal and Artemia worm according to the ratio, and carry out primary crushing and superfine crushing to make the raw material fineness reach 300 mesh, and then add α-starch and yeast according to the ratio Paste, soybean lecithin, DHA, EPA and flour are fully mixed to obtain material A;

[0016] b) Add fish oil, compound mineral salt, compound enzyme preparation, compound immune enhancer, liver-enhancing agent, and compound microecological preparation to material A according to the proportion, and then carry out conditioning and emulsi...

Embodiment 2

[0023] The formula of the full-price fish compound feed components in this example is (unit: Kg): fish meal 40; Insect 4, fish oil 2, soybean lecithin 3, DHA 0.6, EPA 0.4, compound mineral salt 1.8, compound enzyme preparation 0.3, compound immune enhancer 0.3, liver strengthening agent 0.3, compound microecological preparation 0.3.

[0024] The obtained product is through the same test process as in Example 1, and the main technical indicators detected are close to those in Example 1, and will not be repeated here.

Embodiment 3

[0026] The formula of the fish full-price compound feed components in this example is (unit: Kg): fish meal 37; Insect 4, fish oil 2, soybean lecithin 3, DHA 0.6, EPA 0.4, compound mineral salt 1.8, compound enzyme preparation 0.3, compound immune enhancer 0.3, liver strengthening agent 0.3, compound microecological preparation 0.3. The obtained product is through the same test process as in Example 1, and the main technical indicators detected are close to those in Example 1, and will not be repeated here.

Abstract

The invention discloses a perfect compound feed for groupers, which is a compound feed suitable for the culture of grouper large-size fish seeds. The perfect compound feed is prepared by adopting imported fish meal, fermented soybean meal, alpha-starch, flour, squid meal, krill meal, yeast extracts, fairy shrimps, fish oil, soybean phospholipids, DHA (Docosahexaenoic Acid), EPA (Eicosapentaenoic Acid), composite mineral salt, compound vitamins, compound enzyme preparations, compound immunopotentiators, hepatinica and compound microecologic preparations as raw materials. The perfect compound feed disclosed by the invention can promote the digestion and absorption of the groupers, regulate the stability of the intestinal flora of the groupers, enhance the immunity of the groupers and play a lipotropic role by sufficiently considering the digestion and physiology characteristics of the culture period of the groupers and adding various additives to the feed, has the advantages of balanced and complete nutrition without drugs, namely added antibiotics and the like, and no pollution on water bodies and belongs to a high-efficiency environment-friendly nuisanceless feed.

Description

technical field [0001] The invention relates to a fish feed, in particular to a fish full-price compound feed suitable for growing grouper large-scale fingerlings. Background technique [0002] Grouper is a high-end species of marine culture. At present, farmers mostly use chilled miscellaneous fish for cultivation. Although artificial compound feed named after grouper can be seen on the market, its production formula is actually different from that of the so-called grouper. There is no difference in the formulation of seawater fish feed. This kind of feed is difficult to meet the nutritional needs of a certain type of sea fish raised. The characteristics of this type of compound feed are high waste, low absorption and utilization rate, heavy pollution, and poor breeding effect, and it is easy to cause slow growth of farmed fish. Weak constitution and poor resistance to disease and stress seriously restrict the development of grouper aquaculture industry. Although there are...
