Embodiment 1

[0043]

[0044]

[0045] Prepare powdered feed according to the above formula (mass percentage), according to figure 1 The flow chart shown prepares the powdery compound feed for eels, the feed crude protein content is ≥ 38%, and is suitable for feeding eels (≥ 50.0 g) in the fish farming stage.

[0046] With the existing adult fish stage flower eel compound feed (steam fish meal 42%, expanded soybean 14%, peanut meal 5%, a-starch 24%, liver powder 4%, gluten powder 5%, soybean lecithin powder 3.6 %, beer yeast powder 3%, calcium dihydrogen phosphate 1%, mineral matter 1%, betaine 0.5%, choline chloride 0.3%, salt 0.3%, fish multidimensional 0.3%), compared, the present embodiment prepares The cost of the flower eel compound feed was reduced by 1040 yuan / ton.

[0047] Set up the experiment, each group includes 30 adult fish eels with the same body weight, body length, and health. The control group is the existing adult flower eel compound feed, and the experimental grou...

Embodiment 2

[0050]

[0051]

[0052] Prepare powdered feed according to the above formula (mass percentage), according to figure 1 The process shown in the preparation of the flower eel powdery compound feed, the feed crude protein content ≥ 40%, is suitable for feeding the flower eel (10.0-50.0g) in the juvenile stage. Since the protein content and quality of the juvenile fish eel are higher than those of adult fish, the proportion of fish meal is appropriately increased and the content of vegetable protein rice bran is appropriately reduced in the formula.

[0053] With the flower eel compound feed of existing young fish stage (47% of steamed fish meal, 11% of expanded soybean, 5% of peanut meal, 23% of a-starch, 5% of gluten powder, 2.2% of soybean lecithin powder, 5% of brewer's yeast powder %, calcium dihydrogen phosphate 1%, mineral matter 1%, betaine 0.6%, choline chloride 0.5%, salt 0.5%, fish multidimensional 0.2%), compared, the flower eel compound feed that present embodi...

Embodiment 3

[0057]

[0058]

[0059] Prepare powdered feed according to the above formula (mass percentage), according to figure 1 The process shown in the preparation of the flower eel powder compound feed, the feed crude protein content ≥ 42%, is suitable for feeding the flower eel (2.0 ~ 10.0g) of the black baby stage. The black eel stage has low immunity, is prone to disease, and has a high mortality rate. At the same time, it has high nutritional requirements, and has higher requirements for feed attraction and processing performance (viscoelasticity). Therefore, in the formula, the proportion of fish meal is increased to 41%, and the content of vegetable protein rice bran is reduced to 8%. At the same time, the proportion of oligopeptide fish-soluble powder and Cordyceps militaris medium is moderately increased, so as to enhance the physique of flower eel and improve the food-attracting flavor of the feed .

Abstract

The invention discloses an ecology-imitated anguilla marmorata powdery compound feed. The anguilla marmorata powdery compound feed is prepared from a powdery feed, wherein the powdery feed consists ofthe following components in percentage by mass of 28%-45% of steam fish meal, 8%-18% of rice bran, 10%-20% of threonine mycoprotein, 5%-8% of oligopeptide fish soluble powder, 23%-25% of alpha-starch, 3%-5% of beer yeast, 1%-3% of calcium dihydrogen phosphate, 1%-2% of minerals, 0.3%-0.8% of betaine, 0.2%-0.5% of choline chloride, 0.2%-0.5% of table salt and 0.1%-0.3% of multiple vitamins for fishing. For the anguilla marmorata powdery compound feed disclosed by the invention, according to the digestion and ingestion characteristics of anguilla marmorata, selected raw materials are extremelysuitable for ecology-imitated anguilla marmorata breeding; compared with other anguilla marmorata feeds, the anguilla marmorata powdery compound feed pays more attention to reducing feed cost, strengthening organism immunity, preventing occurrence of plant diseases and maintaining the natural body color of the anguilla marmorata. The feed disclosed by the invention is comprehensive in nutrients, body color is natural, breeding effects are good, and the feed has obvious economic benefits.

Description

technical field [0001] The invention relates to an aquatic compound feed, in particular to an ecologically imitative powdered eel compound feed, which belongs to the field of aquatic feed. Background technique [0002] Anguilla marmorata belongs to the family Anguillaidae, commonly known as eel king, reed eel, perch eel, flower eel, etc. It has delicious meat and high nutritional value. It is known as "water ginseng" and is a precious species in fish resources in my country. . The market price of flower eel is 3 to 6 times that of other edible eels, and it has extremely high economic value. In recent years, due to serious pollution of natural water bodies and overfishing, wild eel resources have declined sharply. In 1988, it was listed as a second-class national wild animal protection in my country. At present, due to the lack of seedling resources of Japanese eel and European eel, and the rich resources of seedlings of eel in Southeast Asia, especially the northern part of...
