Embodiment 1
[0038] An active feed suitable for aquaculture, comprising the following components in parts by weight: 10 parts of fish meal, 36 parts of cp46% soybean meal, 8 parts of corn gluten meal, 13 parts of bran, 30 parts of rice bran, 4 parts of brown sugar, 0.4 parts of calcium oxide, 0.04 parts of bile acid, and 1 part of bacteria integration package.
[0039] The preparation method comprises the steps:
[0040] (1) Weigh the raw materials of each component according to parts by weight, ultrafinely pulverize soybean meal, corn gluten powder, and bran to obtain ultrafine pulverization, add fish meal, rice bran, calcium peroxide, and bile to the ultrafine pulverization Acid, brown sugar, mix well to get a mixture;
[0041] (2) Take 1 / 10 of the mixture, mix it with the strain integrated bag and add water, the moisture content of the material after mixing is kept at about 40%, after the strain is activated for 10 hours, then add the remaining amount of the mixture, add water again an...
Embodiment 2
[0050] An active feed suitable for aquaculture, comprising the following components in parts by weight: 10 parts of fish meal, 38 parts of cp46% soybean meal, 10 parts of corn gluten meal, 10 parts of bran, 28 parts of rice bran, 3 parts of brown sugar, 0.4 parts of calcium oxide, 0.05 parts of bile acid, 1.2 parts of strain integration package.
[0051] The preparation method is the same as that of Example 1, and will not be repeated here.
[0052] The moisture content of the feed obtained in this embodiment is about 28%, the crude protein content is about 27.3%, the crude fat content is about 3.4%, and the pH is 4.2.
[0053] From June to August 2019, a tilapia feeding experiment was carried out in two adjacent ponds (the area of a single pond is about 2 mu) in the pilot test base of a large aquatic feed company. Tail tilapia, the average size of the selected tilapia is 0.2 catties / tail. Control group feeding crude protein content is 30% tilapia commercial extruded feed, ...
Embodiment 3
[0059] An active feed suitable for aquaculture, comprising the following components in parts by weight: 5 parts of fish meal, 40 parts of CP46% soybean meal, 6 parts of corn gluten meal, 16 parts of bran, 28 parts of rice bran, 4 parts of brown sugar, 0.5 parts of calcium oxide, 0.04 parts of bile acid, and 1.1 parts of bacteria integration package.
[0060] The preparation method is the same as that of Example 1, and will not be repeated here.
[0061] The moisture content of the feed obtained in this embodiment is about 28.2%, the crude protein content is about 26.2%, the crude fat content is about 3.0%, and the pH is 4.3.
[0062] From May to June 2019, two cages in a 80-acre pond of a farmer in Guangdong were used to carry out a feeding experiment of silver carp. They were divided into a test group and a control group. The size of the selected cages was 6m×6m×2m. The average specification of silver carp is 305g / tail; Test group puts 60 tail silver carp in a suitable place...
