Preparation method of blunt-snout bream fodder

Abstract

The invention relates to a preparation method of blunt-snout bream fodder. The blunt-snout bream fodder comprises the following raw materials in percentage by weight: 8 to 11 bean cake, 3 to 6 barley, 5 to 12 rapeseed cake, 2 to 6 bran cake, 5 to 11 bran coats, 18 to 35 corn meal, 6 to 9 cotton bran, 10 to 18 rough fish meal, 3 to 9 loach meal, 1 to 2 rapeseed oil phospholipid, 1 to 3 premix additive, 5 to 8 crude protein meal and 1 to 2 multiplex vitamin. The preparation method of the blunt-snout bream fodder comprises the following steps: pouring the materials into a fodder pulverizer to pulverize; taking out and putting the pulverized matter into a stirrer to stir for 60 minutes; then, taking out and fully pouring the mixture into a circular mould type hard granulator to generate sediment hard granule fodder; and screening the sediment hard granule fodder by a 40-mesh net so that each granule has the weight of 0.2g.

Description

technical field

[0001] The invention relates to a preparation method of fish feed, in particular to a preparation method of roundhead bream fish feed. Background technique

[0002] Bubble bream, also known as Wuchang fish, has a small head and a lot of meat, and the meat is tender and delicious. In recent years, it has been used as a high-quality species in Hubei, Jiangsu, Shanghai and the Yangtze River Basin. Bramy bream is a herbivorous fish. In natural waters, it mainly feeds on plants such as bitter grass, hydrilla verticillum, and polyphylla. At present, with the popularization of artificial feeding, compound feed is the main feeding method, but the nutrients in the ingredients are not very reasonable, and the content of various proteins and vitamins is relatively low, which is very unfavorable to the growth of roundhead bream. Therefore, A high-quality fish feed with reasonable ratio and relatively uniform nutrition is needed. Contents of the invention

Examples

Embodiment 1

[0007] Example 1: bean cake 8%, barley 3%, vegetable cake 5%, bran cake 6%, bran 5%, corn flour 35%, cottonseed meal 6%, miscellaneous fish meal 18%, loach meal 3%, rapeseed oil 1 %, 1% of premix additive, 8% of crude protein powder, and 1% of multivitamins, and the stated percentages are percentages by weight.

[0008] Pour the above-mentioned substances into a feed grinder in proportion to pulverize them, take them out and put them into a mixer for 60 minutes, then take them all out and pour them into a ring mode hard pellet unit to produce precipitated hard pellet feed, and then sieve it with 40 meshes, The grain weight is 0.2 g.

[0009] Fishmeal, premix additives and multivitamins in this formula are all purchased from the market.

[0010] The example of using the feed of the present invention to raise bream, such as: Liguo Shanghe, Tongshan County, Jiangsu Province, Fang Zhongmin of the Weishan Lake bream fish farm, utilizes the feed prepared by the present invention to...
