Embodiment 1

[0069] Embodiment 1, the most basic components by weight of the present invention are as follows:

[0070] Fishmeal 55.0%;

[0071] Pregelatinized starch 24.0%;

[0072] Fermented soybean meal 7.0%;

[0073] Expanded soybean 7.0%;

[0074] Fish oil 0.6%;

[0075] Brewer's yeast 4.0%;

[0076] Minerals 1.0%;

[0077] Calcium dihydrogen phosphate 1.0%;

[0078] Choline Chloride 0.2%;

[0079] Multidimensional 0.2%.

[0080] The feed was prepared according to the formula shown in the above table, and the adult eels were raised for 35 days. The adult eels that ingested the feed of this embodiment were more active in ingesting food, had better feed viscoelasticity, better stability in water, higher feed conversion rate, faster fish growth, and better economic benefits.

Embodiment 2

[0081] Embodiment 2, the content of each component after adding an appropriate amount of additives in the present invention is as follows:

[0082] Fishmeal 52.0%;

[0083] Pregelatinized starch 23.0%;

[0084] Fermented soybean meal 7.0%;

[0085] Expanded soybean 7.0%;

[0086] Fish Oil 2.0%;

[0087] Brewer's yeast 5.0%;

[0088] Minerals 2.0%;

[0089] Calcium dihydrogen phosphate 1.0%;

[0090] Choline Chloride 0.2%;

[0091] Multidimensional 0.2%;

[0092] Coated Vitamin C 0.1%;

[0093] Betaine 0.2%;

[0094] Antioxidant 0.02%;

[0095] Salt 0.28%.

[0096] The feed was prepared according to the formula shown in the above table, and the adult eels were raised for 35 days. The adult eels that ingested the feed of this embodiment were more active in ingesting food, had better feed viscoelasticity, better stability in water, higher feed conversion rate, faster fish growth, and better economic benefits.

Embodiment 3

[0097] Embodiment 3, the content of each component after adding an appropriate amount of additives in the present invention is as follows:

[0098] Fishmeal 54.0%;

[0099] Pregelatinized starch 25.0%;

[0100] Fermented soybean meal 8.0%;

[0101] Expanded soybean 4.5%;

[0102] Fish oil 1.5%;

[0103] Brewer's yeast 4.0%;

[0104] Minerals 1.5%;

[0105] Calcium dihydrogen phosphate 0.5%;

[0106] Choline Chloride 0.2%;

[0107] Multidimensional 0.2%;

[0108] Coated Vitamin C 0.1%;

[0109] Betaine 0.2%;

[0110] Antioxidant 0.02%;

[0111] Salt 0.28%.

[0112] The feed was prepared according to the formula shown in the above table, and the adult eels were raised for 35 days. The adult eels that ingested the feed of this embodiment were more active in ingesting, the feed had good viscoelasticity, good stability in water, high feed conversion rate, fast fish growth, and good economic benefits.

Abstract

The invention discloses powdery compound feed for the anguilla marmorata adult stage. The powdery compound feed comprises fish meal, pre-gelatinized starch, fermented soybean meal, extruded soybean, fish oil, beer yeast, mineral, monocalcium phosphate, choline chloride, vitamin complex and the like. Compared with the traditional feed, the powdery compound feed for the anguilla marmorata adult stage, disclosed by the invention, has the advantages of comprehensive nutrition, little pollution to culture water and wide source of raw materials; and compared with the existing powdery compound feed for the Japanese eel adult stage, the powdery compound feed for the anguilla marmorata adult stage, disclosed by the invention, has the advantages of high feed conversion rate, high digestion utilization rate, high protein content, low fat content, no need of coloring components and the like, and is green and pollution-free.

Description

technical field [0001] The invention relates to the field of fish feed, in particular to the field of powdery compound feed for eel adult stage. Background technique [0002] Flower eel ( Anguilla marmorata ), commonly known as perch eel, flower eel, etc., are widely distributed in tropical, subtropical and temperate regions of the world. Flower eel has good meat quality, delicious taste, high protein and fat content, and has always been regarded as a first-class nourishing food with high economic value. However, due to factors such as overfishing, the blocking of normal migration channels, and the deterioration of the habitat and growth environment, the resources of the flower eel have declined sharply, and it has now been listed as a second-class wild animal under protection in my country. At present, my country's Hainan, Guangdong, Fujian and other places are actively developing the flower eel aquaculture industry, and have achieved certain results. However, limited by...
