Embodiment 1

[0054] fish meal 30.4% Oligopeptide Fish Dissolved Powder 5% Oligopeptide soybean meal 16% a-starch 25% puffed soybeans 3% puffed corn 10% beer yeast 5% minerals 2% fish multidimensional 0.2% Choline chloride 0.4% betaine 0.5% Calcium Dihydrogen Phosphate 2% salt 0.5%

[0055] Formulate powdered feed according to the formula shown in the table above, suitable for feeding overwintering flower eels at the adult stage. The crude protein content of the feed is ≥38%. Compared with other compound feeds at the adult stage of flower eels, it has low cost, good food-attracting properties, and good viscoelasticity. Good, the flower eel grows fast, the breeding effect is good, and the economic benefit is good.

Embodiment 2

[0057] fish meal 35% Oligopeptide Fish Dissolved Powder 5% Oligopeptide soybean meal 15% a-starch 24.5% puffed soybeans 3% puffed corn 10% beer yeast 3.8% minerals 1.2% fish multidimensional 0.2% Choline chloride 0.4% betaine 0.3% Calcium Dihydrogen Phosphate 1.2% salt 0.4%

[0058]Formulate powdered feed according to the formula shown in the above table, which is suitable for feeding the overwintering flower eel in the juvenile stage. Since the nutritional requirements of juvenile fish are higher than those of adult fish, the proportion of fishmeal is appropriately increased, and the crude protein content of the feed is ≥ 43%. The overwintering compound feed for flower eel of this embodiment is lower in cost and more attractive than other compound feeds for flower eel juvenile stage. Good feeding habits, good viscoelasticity, fast growth of flower eel, good breeding effect and good economic ...

Embodiment 3

[0060] fish meal 40% Oligopeptide Fish Dissolved Powder 5% Oligopeptide soybean meal 15% a-starch 23% puffed soybeans 3% puffed corn 7.8% beer yeast 3% minerals 1% fish multidimensional 0.2% Choline chloride 0.3% betaine 0.3% Calcium Dihydrogen Phosphate 1% salt 0.4%

[0061] Formulate powdered feed according to the formula shown in the above table, which is suitable for feeding overwintering flower eels in the black baby stage. Heizi stage not only has high nutritional requirements, but also has higher requirements for viscoelasticity, so the amount of fishmeal is increased to 40%, and the crude protein content of feed is ≥45%. The overwintering compound feed for flower eel of this embodiment is low in cost and good in attracting food compared with other compound feeds for the black baby stage of flower eel. Good economic benefits.

Abstract

The invention discloses a powdery formulated feed for anguilla marmorata overwintering, wherein a technical process for the same comprises the following step of: preparing the powdery formulated feed for anguilla marmorata overwintering from various raw material constituents according to a powdery feed processing method. The powdery formulated feed for anguilla marmorata overwintering comprises the raw material constituents in percentage by weight: fish meal, alpha-starch, extruded soybean, oligopeptide soybean meal, beer yeast, mineral substances, finishing multi-vitamins, choline chloride, monocalcium phosphate and the like. Compared with other feeds, the powdery formulated feed for anguilla marmorata overwintering disclosed by the invention is remarkably increased in the contents of oligopeptides and plant proteins, and obviously reduced in the dosage of fish meal; via the addition of the plant proteins, the cost of the feed is decreased, and the feed is more comprehensive in nutrition; meanwhile, via the addition of the oligopeptides and the proteins, feeding attraction property and body disease resistance can be further improved. By using the powdery formulated feed for anguilla marmorata overwintering disclosed by the invention, the nutrition state of an anguilla marmorata overwintering group can be greatly improved, the digestive utilization of the feed can be promoted, and the body immunity of anguilla marmorata can be enhanced.

Description

technical field [0001] The invention relates to the field of aquatic product compound feed, in particular to the field of powdered compound feed for eel. Background technique [0002] Flower eel ( Anguilla marmorata ) belongs to the family Eelidae of the order Eelidae, with delicious meat and high nutritional value, known as "ginseng in water", 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 water pollution, human overfishing, damming and other reasons, the wild resource of flower eel has declined sharply, and it is now listed as a second-class wild animal by the state. In order to save the endangered eel population and increase the total amount of eel resources in my country, Hainan, Guangdong, Fujian and other places in China are actively developing the eel breeding industry and have achieved certain results. [0003] At ...
