Embodiment 1

[0044] The seven-color angelfish feed preferably comprises the following components in parts by weight: 35 parts of grass insect powder, 25 parts of shrimp meat powder, 5 parts of α-starch, 1.5 parts of immature green banana peel extract, 2 parts of soybean oil, vegetable 0.5 parts of seed oil, 0.5 parts of perilla seed oil, 0.15 parts of taurine, 4 parts of amino acid premix, 3 parts of vitamin premix, 3 parts of minerals, 0.8 parts of potassium selenite, 0.5 parts of astaxanthin, Lutein 0.5 part, retinol 0.5 part, β-glucan 1 part, lecithin 1 part, choline chloride 0.3 part, sodium dihydrogen phosphate 0.8 part, salt 0.5 part.

[0045] Preparation:

[0046] 1) Grind the feed raw materials, mix them according to the principle of superimposing a small amount, pass through a 200-mesh sieve, and mix them with a mixer for 10 minutes to obtain a mixed feed; perform wet granulation on the mixed feed and wall materials, and then place them in a fluidized bed to dry, Use wall materia...

Embodiment 2

[0058] The feed granule of the present invention that makes with embodiment 1 is as test group, the control feed granule that makes with comparative example 1 is as control group, the seven-color angel fish that artificially breeds with ornamental fish laboratory is experimental fish, average body weight (16.74 ± 0.65 ) g, the experiment was randomly divided into 2 groups, each group had two parallels, and 20 healthy fish with no injuries were selected for each parallel, a total of 80 fish. The experimental fish were kept in 4 aquariums with automatic air circulation, and the beef heart burger was frozen and cut into 0.3-0.5m 3 The amount of feeding is 3-4% of the body weight of the experimental fish. It is advisable to finish eating within 2-3 minutes. It is fed 3 times a day (8:30, 12:30, 16:30). During the test, the water temperature ( 27±1)°C, pH 6.8-7.6. The breeding cycle is 8 weeks.

[0059] After the end of the experiment, starve for 24 hours, weigh the body weight, ...

Embodiment 3

[0068] Gastrointestinal Enzyme Activity Determination of Discus Fish

[0069] Feeding program is identical with embodiment 2. After feeding, the gastrointestinal enzyme activity was measured, and the results are shown in Table 2

[0070] The assay method of specific enzyme activity is as follows:

[0071] Protease activity is determined by Folin-phenol method, protease activity unit = (A ÷ 15) × F, the definition of protease activity unit: 1 μg of tyrosine produced by hydrolyzing casein per minute at 37°C is 1 enzyme activity unit (U ).

[0072] Amylase activity is measured by starch-iodine colorimetric method, amylase activity unit = (optical density of control tube - optical density of measurement tube) ÷ optical density of control tube × 800, definition of amylase activity unit: at 37°C, within 30 minutes, 100mL The amylase in the enzyme liquid can completely hydrolyze 10 mg of starch, which is an enzyme activity unit.

[0073] Lipase activity is determined by milk-NaOH...

Abstract

The invention discloses a symphysodon aequifasciata feed. Based on the weight of the feed, the prepared feed comprises 0.01-99% of grass worm powder, 0.01-50% of banana peel extract and potassium selenite. The feed preferably further comprises 3-7% of carbohydrate, 10-45% of proteins, 5-15% of fat and added vitamins and amino acids. The invention also discloses a preparation method of the symphysodon aequifasciata feed. The feed has the beneficial effects that a common beef heart hamburger feed is replaced by tylorrhynchus powder and shrimp meat powder, and grease rich in linolenic acid and linoleic acid is used as a fat source which matches with nutrient substances such as the green banana peel extract rich in 5-hydroxytryptophan, sodium selenite, amino acids, vitamins and minerals The feed can provide balanced nutrients, essential amino acids and essential fatty acids for symphysodon aequifasciata, promote gastrointestinal enzyme activity of symphysodon aequifasciata, increase appetite, and promote growth. The symphysodon aequifasciata feed can be preserved for a long time, and the complicated steps that the symphysodon aequifasciata feeds in the prior art need to be prepared onthe site and freezing storage are avoided.

Description

technical field [0001] The invention relates to the field of aquatic feed processing, in particular to a seven-color angel fish feed. Background technique [0002] Seven-color angelfish belongs to the genus Cichlidae and is native to the Amazon River Basin in South America. It is a rare species in the ornamental fish market. [0003] The fresh and frozen "beef heart burger" is mainly used in the breeding of seven-color angelfish. This kind of feed operation is loaded down with trivial details, and cost is high, and easily spoils water quality and makes fish sick. Therefore, it is a problem to be solved urgently for those skilled in the art to provide a kind of discus fish feed which is easy to store, has balanced nutrition and good palatability. [0004] Grass worm, also known as warty snout clamworm, has a slender and slightly flat body, 40-80 mm long and 5 mm wide, and is widely distributed in the estuaries of the Yellow Sea, the East China Sea and the South China Sea. ...
