Because large yellow croaker is a fish in shallow water, most of the current feed for large yellow croaker is extruded material, which can float on the water surface and is convenient for large yellow croaker to eat. However, as the oil on the surface of the expanded material is gradually washed away by the water body, the expanded material The feed will slowly absorb water and dissolve, resulting in waste of feed

Embodiment 1a
[0047] A preparation method for large yellow croaker feed, comprising the following steps:
[0048] Step1, use a feed mill to grind 20kg of high-gluten flour, 48kg of fish meal, 8kg of corn gluten meal, 13kg of soybean meal, 2kg of calcium dihydrogen phosphate, 0.05kg of multivitamin, 0.25kg of multivitamin, 0.25kg of raw amino acid powder, and 0.05kg of probiotics After pulverizing and stirring evenly, pass through a 100-mesh sieve to obtain the mixture;
[0049] Step2, put the pulverized mixture into a differential pressure extruder for pre-expansion to obtain a pre-expanded material;
[0050] Step3, mix 2kg of fish oil, 0.01kg of antioxidant, and 0.04kg of preservative evenly, then add it to the pre-expanded material, stir evenly and dry it to obtain the dried material;
[0051] Step4, putting the dried material into the differential pressure extruder again for extruding to obtain the large yellow croaker feed.
[0052] Multivitamins were purchased from Jinan Hongtu Chemi...
Embodiment 1
[0059] The preparation method of Example 1b-Example 1e is the same as that of Example 1a, the difference is that the components and the specific content of the components of Example 1b-Example 1e are different from Example 1a. See the table below for details (unit: kg):

[0061]
Embodiment 2a
[0063] A preparation method for large yellow croaker feed, comprising the steps of:
[0064] Step1, dissolve 0.3kg of cornstarch, 0.2kg of propolis, 0.1kg of guar gum, 0.05kg of lotus leaf powder, and 0.02kg of sodium carboxymethyl cellulose in 10kg of water and stir to obtain a thick liquid;
[0065] Step2, use the feed obtained in Example 1a as the puffed body, spray the viscous liquid on the surface of the puffed body, the nozzle diameter is 0.1mm, the nozzle pressure is 10Mpa, and after blast drying at 50°C, a rough polysaccharide layer with a thickness of 0.1mm is obtained ;
[0066] Step3, after drying 0.5kg of beeswax at 50°C with air blast, mix it with 2L of water and pulverize it evenly with an ultrafine pulverizer to obtain a micron-sized edible wax suspension;
[0067] Step4, take part of the micron edible wax suspension and add it to the nano grinder to continue grinding evenly to obtain the nano edible wax suspension;
[0068] Step5, after mixing the nano-scale ...

Abstract
The invention relates to novel feed manufacturing, and specifically relates to a larimichthys crocea feed and a preparation method thereof. The larimichthys crocea feed solves the problem of feed waste caused by gradual melting of puffed feeds due to absorption of water for oil on surface of the puffed feeds is gradually washed away by the water. A key point of the technical scheme of the larimichthys crocea feed is that the larimichthys crocea feed comprises extruded substances and hydrophobic coating coats on periphery of the extruded substances; the extruded substances are composed of the following raw materials in parts by mass: 20-24 parts of high-gluten-content flour, 48-52 parts of fish meal, 8-10 parts of corn protein powder, 13-15 parts of soybean meal, 2-3 parts of calcium dihydrogen phosphate, 2-3 parts of fish oil, 0.05-0.15 part of compound vitamins, 0.25-0.35 part of compound minerals, 0.25-0.35 part of original amino acid powder, 0.01-0.03 part of an antioxidant, 0.04-0.06 part of a preservative, and 0.05-0.15 part of probiotics. The larimichthys crocea feed achieves the goal of delaying water absorption rate so as to reduce feed waste; moreover, the feed is capableof enhancing physique of larimichthys crocea, so that larimichthys crocea fed with the feed has the characteristics of being strong in disease resistance, high in survival rate and rapid in growth speed. Thus, the larimichthys crocea fed with the feed is close to wild larimichthys crocea in terms of appearance and color.
Description
technical field [0001] The invention relates to novel feed manufacture, in particular to a large yellow croaker feed and a preparation method thereof. Background technique [0002] Large yellow croaker (Larimichthys crocea), bony fish class, perciformes (Perciformes), stone head fish family (Sciaeni-dae), yellow croaker genus, also known as yellow croaker, king fish, big fresh, big yellow croaker, red melon, golden dragon, Golden dragon, osmanthus yellow croaker, big croaker, red mouth, totoaba, stone fish, and cucumber fish are one of the traditional "four seafood" (large yellow croaker, small yellow croaker, hairtail, squid), and are the main economic fish in my country's coastal waters. [0003] Large yellow croaker is the marine fish with the largest cage culture output in my country. In 2016, the total national output reached 165,500 tons. At present, the feeding and feeding of large yellow croaker is still mainly chilled fish, but the source of chilled fish is unstable...
