Problems solved by technology

However, with the improvement of the degree of intensive farming, the disease is becoming more and more serious. Because the prawn feed obviously lacks biologically active substances, under the current situation of the prevalence of prawn diseases, aggravated water pollution, and bad and changeable weather, with the prohibition of antibiotics, more and more More and more professionals pay attention to the development and application of green environmental protection immune enhancers that are pollution-free, residue-free, growth-promoting, and enhance the immunity of aquatic animals

Embodiment 1

[0019] Main technology of the present invention is as follows:

[0020] Batching→impurity removal→iron removal→mixing→crushing→superfine pulverization→mixing→conditioning→granulation→post-cooking→cooling→packaging.

[0021] Pretreatment: Lumpy raw materials need to be pulverized before batching. After the raw material enters the cleaning screen, the impurities in the raw material are separated, and then the iron filings are removed by the magnetic separator. It is very important to remove impurities and iron. It can not only ensure the quality of the feed, but also protect the equipment and prolong the life of the equipment.

[0022] Superfine grinding, shrimp pellet feed, requires the particle size of raw materials to reach 80-100 mesh. In this way, the quality of the feed can be improved, the digestibility of the prawn feed can be enhanced, and the absorption effect is good; at the same time, the particles are fine, the ability to absorb water is enhanced, the adhesion is ...

Embodiment 2

[0031] The specifications of the pellets are that the diameter of the pellets is 2 mm, and the length of the pellets is 5 mm. The granules are brownish-yellow, neat in shape, full of luster and special feed aroma.

[0032] Feed ingredients: protein 39%-41%, carbohydrate 34%-36%, fat 7%-8%, ash 7%-8%, moisture <11%, fiber 14%-17%, calcium 16-17%, phosphorus 10-12%.

[0033] The nutrient composition of the feed meets the nutritional requirements of the pre-adult shrimp, and can well promote the growth of the prawn.

[0034] The water content of the feed is below 11%, and it contains a certain amount of anti-mold agent, so the feed is not easy to mold and has a long shelf life.

[0035] Stability of Feed The feed is soaked in seawater for 2 hours, and its loss rate is less than 10%, so as to ensure the feeding of prawns, prevent water pollution, and maintain good water quality, which is beneficial to the growth of prawns.

Abstract

The invention discloses a feed for prawns, which includes, by weight, 34% of fishmeal, 9% of soybean meal, 5% of peanut meal, 2% of shrimp head powder, 3% of squid viscera powder, 2% of feed yeast, 34% of flour, 1% of fish oil, 1% of soybean lecithin, 0.15% of feed essences, 5% of a binder, 1% of a vitamin premix, 2% of a mineral premix, and 0.15% of a feed mildew proofing agent. The feed has abundant nutrients, is not liable to mildew, has long shelf life and effective reduces water pollution.

Description

technical field [0001] The invention belongs to the technical field of feed and breeding, in particular to a prawn feed and a preparation method thereof. Background technique [0002] With the continuous development of the economy and the continuous improvement of people's living standards, the demand for prawns is increasing year by year. my country is a big country for prawn farming, especially in recent years, the development momentum has become increasingly rapid. In 2003 alone, the total output of cultured prawns in the country reached 800,000 tons, which created huge economic benefits for my country's export earnings. However, with the improvement of the degree of intensive farming, the disease is becoming more and more serious. Because the prawn feed obviously lacks biologically active substances, under the current situation of the prevalence of prawn diseases, aggravated water pollution, and bad and changeable weather, with the prohibition of antibiotics, more and mo...
