Problems solved by technology

However, when the temperature is too high, the eel will feel anorexia, and the food intake will decrease instead, so that the eel cannot maintain rapid growth, resulting in low eel output, high feed coefficient, and high breeding costs.

preparation example Construction

[0021] The preparation method of the feed is as follows: pulverize the first raw material to a particle size of 10-50 μm, decoct it with water for 2-4 hours until it becomes a paste, and obtain the first processed material; pulverize the second raw material to a particle size of 10-50 μm, mix well and mix Aging and granulation to obtain the second processed material; coating the first processed material on the surface of the second processed material and drying.

[0022] Eel is a carnivorous animal, easy to absorb animal protein, and likes to eat meat with a strong fishy smell such as earthworms. The invention adopts earthworm meal and fish meal as the main source of protein, which can promote the eel to eat, and the eel can absorb the protein well, which is helpful for its rapid growth.

[0023] Further, in the present invention, fish meal includes mackerel meal and pollack meal.

[0024] Mackerel and pollack are marine fish, which taste fresher than freshwater fish, and are...

Embodiment 1

[0044] A method for preparing eel feed during the summer period, comprising:

[0045] Weigh 11kg mackerel meal, 37kg pollack meal, 18kg earthworm powder, 7kg garlic, 1.5kg clove, 1.5kg woody fragrance, 0.8kg tangerine peel, 2.5kg mint, 1.5kg Huoxiang, 1.5kg Perrin and 0.8kg Radix Ophiopogon japonicus. The diameter is 30 μm, adding water and decocting for 3 hours until it becomes a paste, and the first processed material is obtained.

[0046] Weigh 6kg soybean oil, 9kg cornstarch, 9kg potato starch, 18kg wheat bran, 0.8kg pure top spirulina and 0.8kg maximal spirulina. The starch is loaded into an extruder and expanded at a temperature of 220° C. and a pressure of 0.7 MPa. The expanded starch was mixed with soybean oil, wheat bran and algae and crushed to 30 μm, and the second processed material with a particle size of 400 μm was obtained by aging and granulating with a feed aging granulator.

[0047] Coating the first processing material on the surface of the second processi...

Embodiment 2

[0049] A method for preparing eel feed during the summer period, comprising:

[0050] Weigh 10kg mackerel meal, 35kg pollack meal, 15kg earthworm powder, 6kg garlic, 1kg clove, 1kg woody fragrance, 0.5kg tangerine peel, 2kg mint, 1kg Huoxiang, 1kg Peilan and 0.5kg Ophiopogon japonicus and pulverize until the particle size is 10μm, add water Decocting for 2 hours until it becomes a paste, the first processed material is obtained.

[0051] Weigh 5kg soybean oil, 5kg cornstarch, 10kg potato starch, 15kg wheat bran and 1kg pure spirulina. The starch is loaded into an extruder and expanded at a temperature of 200° C. and a pressure of 0.6 MPa. The expanded starch was mixed with soybean oil, wheat bran and algae and crushed to 10 μm, and the second processed material with a particle size of 300 μm was obtained by aging and granulating with a feed aging granulator.

[0052] Coating the first processing material on the surface of the second processing material and drying.

Abstract

The invention provides an eel feed for an over-summering period and a preparation method thereof and belongs to the field of aquiculture. The feed is prepared by wrapping a second processing material with a first processing material, wherein the first processing material is prepared by decocting a first raw material with water; the second processing material is prepared from a second raw material by aging and granulating; the first raw material is prepared from the following ingredients in parts by weight fish meal, earthworm powder, garlic, clove, radix aucklandiae, dried tangerine or orange peel, mint, wrinkled gianthyssop, herba eupatorii and radix ophiopogonis; the second raw material is prepared from the following ingredients in parts by weight: bean oil, starch, wheat bran and algae. The method comprises the following steps: pulverizing the first raw material to a particle size of 10-50 [mu]m, decocting the pulverized material with water for 2-4 hours until a paste is obtained, thereby obtaining the first processing material; pulverizing the second raw material to a particle size of 10-50 [mu]m, and conducting aging and granulating, thereby obtaining the second processing material; and wrapping the second processing material with the first processing material, and conducting drying. The method is simple; the prepared feed has effects of inducing eels to eat the feed, strengthening the spleen and reinforcing the stomach, promoting nutrient absorption and removing summer-heat, so that eels are high in growth speed, high in survival rate and low in feed coefficient during summer culture.

Description

technical field [0001] The invention relates to the field of aquaculture, and in particular to a feed for eels in the oversummer period and a preparation method thereof. Background technique [0002] Eels belong to the order Synbranchidae, the Synbranchidae, and the genus Eel. The eel meat is tender and delicious. Eel is rich in DHA and lecithin, which are the main components of the cell membranes of various organs and tissues of the human body, and are indispensable nutrients for brain cells, so eel has the effect of nourishing the brain and keeping fit. The unique substance "salmonin" of eel has the functions of clearing heat and detoxifying, cooling blood and relieving pain, dispelling wind and swelling, moistening intestines and stopping bleeding, etc. It can lower blood sugar and regulate blood sugar, and has a good therapeutic effect on hemorrhoids and diabetes. Contains very little fat, so it is an ideal food for diabetics. Eel also has extremely high vitamin A con...
