Preparation method of herring feed

Abstract

The invention relates to a preparation method of herring feed which comprises the following components according to the weight percent: 5-15 percent of fish meal, 15-34 percent of bean cake, 3-9 percent of barley, 10-16 percent of rape-seed cake, 3-8 percent of bran, 18-20 percent of corn, 3-8 percent of bone meal, 5-9 percent of silkworm pupa, 1-2 percent of salt, 1-3 percent of premix additive, 2-4 percent of multiplex vitamin and 2-4 percent of mineral composition additive. The preparation method comprises the following steps: pouring the materials into a container, uniformly mixing, producing settled hard granulated feed by a loop mode hard granulation machine, and sieving by a 40-mesh sieve, wherein the weight of each grain is 0.1g.

Description

technical field

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

[0002] Herring is an animal fish, and it is a favorite high-quality fish for urban and rural people in Jiangsu, Zhejiang, Shanghai and other places. In natural waters, it mainly feeds on molluscs such as snails and mussels, so people often call it animal fish. 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 herring, so a kind of It is a high-quality fish feed with reasonable ratio and relatively uniform nutrition. Contents of the invention

[0003] The purpose of the present invention is to provide a high-quality compound feed that is low in cost, reasonable in proportion of various nutritio...

Examples

Embodiment 1

[0007] Embodiment 1: fish meal 15%, bean cake 15%, barley 9%, vegetable cake 10%, bran 8%, corn 18%, bone meal 8%, silkworm chrysalis 5%, salt 1%, premix additive 3%, more Kind of vitamin 4%, mineral agent 4%, described percentage is percentage by weight.

[0008] Pour the above-mentioned materials into the container in proportion and mix well, produce precipitated hard pellet feed with a ring mode hard pellet unit, then sieve with 40 meshes, and the weight of each pellet is 0.1 gram.

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

[0010] Use the example of herring of the present invention, as: Yin Hongyu of Yunhe Farm, Maocun Town, Tongshan County, Jiangsu Province, utilizes the feed prepared by the present invention to raise 6800 herrings, raise 318 days and catch, and the average weight of every herring is 4.96 kilograms, which is the same as that without Compared with the farmers who use the feed of the present in...
