Description

A kind of large water surface healthy grass carp compound feed and production method thereof

technical field

The invention relates to the technical field of aquaculture feed, in particular to a compound feed for healthy grass carp aquaculture in a large water surface and a production method thereof.

Background technique

Grass carp is the largest main species in my country, accounting for 20% of freshwater fish production, and it is also a freshwater fish species that people often eat and love. Grass carp meat is tender and tender, with few bony spurs and rich nutrition. Every 100 grams of grass carp meat contains 17.9 grams of protein, 4.3 grams of fat, multivitamins, and rich unsaturated fatty acids, which are good for blood circulation and are good for cardiovascular patients. good food. However, grass carp is also the most disease-prone, and the outbreak of grass carp disease often brings a devastating blow to the farming in some areas.

At present, the competition in grass carp farming mainly lies in the cost of feed and the survival rate of stocking. On the one hand, due to the increase in world food prices, the feed cost of grass carp farming is also increasing; on the other hand, the existing compound feeds are not mainly aimed at improving the immunity of grass carp, and cannot greatly reduce the loss of fish death. Households have used antibiotics to reduce the morbidity of grass carp, but the residues of antibiotics will cause great harm to the human body. Therefore, it is an urgent need in this technical field to develop a health-care feed with relatively low cost, comprehensive nutrition, and enhanced grass carp immunity.

Contents of the invention

In order to overcome the shortcomings of the prior art above, the present invention provides a compound feed for healthy grass carp farming that can enhance the self-immunity of grass carp, has comprehensive nutrition, high absorption rate and low cost and a production method of the compound feed.

The technical scheme of the present invention is: a compound feed for healthy grass carp cultured on a large water surface, which is formed by proportioning the following raw materials in parts by weight: 10-20 parts of bean cake, 15-25 parts of vegetable cake, 10-20 parts of cotton cake, wheat 10-19 parts of bran, 10-15 parts of secondary flour, 10-20 parts of rice bran, 3-6 parts of shell powder, 5-10 parts of wheat flour, 4-8 parts of orange stem powder, 0.1-0.2 parts of Artemisia annua powder, wolfberry 0.01-0.05 parts of dry powder, 0.1-0.2 parts of multivitamins, 10-20 parts of liquid lactic acid bacteria (5-1 billion/ml), 20-40 parts of water, 0.1-0.5 parts of salt.

The production method of above-mentioned grass carp compound feed, its processing step is:

The first step, weighing various raw materials according to the proportion;

The second step is to mix bean cake, vegetable cake, cotton cake, wheat bran, sub-flour, rice bran and shell powder among the raw materials, add liquid lactic acid bacteria and water, put them into a fermentation tank, and ferment while stirring at 25-65°C 30-72h;

The third step is to take out the fermented material in the second step, air-dry under reduced pressure at 30-65°C until the moisture content is 5-12%, and then add wheat flour, orange stalk powder, artemisia annua powder, and wolfberry dry powder , multivitamins, and salt are fully mixed to obtain a mixture;

The fourth step is to make the mixture in the third step into pellet feed.

The invention has the following advantages: 1. The granule feed is rich in nutrients and minerals, and has sufficient vitamin content. It uses liquid lactic acid bacteria to ferment, converts plant protein into animal protein, and replaces the original fish meal, which not only reduces the cost, but also solves the source of animal protein. , and its absorption and utilization rate is high; 2. In addition, orange stalk powder maintains the cellulose required by grass carp. While improving the quality of grass carp meat, it can increase the growth rate of grass carp after eating by more than 8%, and reduce the production cost of grass carp feed by 5% %, reduce the cost of grass carp breeding by more than 10%; 3. The addition of dry wolfberry powder and multivitamins improves the immune function of grass carp, enhances the ability of grass carp to prevent, cure and resist viruses, and the return rate of grass carp can be increased by 5%. .
