Abstract

The invention provides a prawn granule feed. The prawn granule feed is characterized by being prepared from the following components in percentage by weight: 20%-25% of white fish meal, 15%-20% of domestic fish meal, 15%-20% of soybean meal, 10%-15% of peanut bran, 20%-25% of flour, 2%-3.5% of cuttlefish cream, 10%-15% of shrimp shell powder, 2%-2.5% of phosphatide oil, 2%-2.5% of fish oil, 1%-1.5% of calcium dihydrogen phosphate, 0.5%-0.8% of table salt, 0.4%-0.8% of shelling elements, 0.2%-0.4% of choline chloride, 0.1% of a composite microecological preparation, 0.1% of a composite hepatobiliary preparation, 0.3%-0.5% of vitamin C, 1.5% of complex vitamins and 2.0% of complex mineral salt. The prawn granule feed is produced according to the following method: feeding raw materials, coarse grinding, performing treatment in a raw material bin, preparing materials, mixing for the first time, ultrafine crushing, screening, mixing for the second time, performing pelletization, cooling, sieving, and packing so as to obtain finished products. The prepared prawn granule feed disclosed by the invention is suitable for South America white shrimps, macrobrachium rosenbergii, freshwater shrimps, mixed cultured shrimps and crabs and the like, of which the length is 2.0-4.5cm. According to different nutritional requirements of prawns at different growth phases, protein levels are reasonably set, so that nutritional requirements are met, the growth rate is increased, waste of protein resources can also be effectively reduced, and the economic benefits are increased.

Description

Prawn pellet

Technical field

The present invention relates to a kind of feed, particularly a kind of prawn pellet.

Background technology

Shrimp culture industry has been the industry pillar of China's aquaculture high added value since the eighties always.At present, China has become the country that cultured prawn variety yield is maximum in the world.China's prawn culturing mainly concentrates on Guangdong, Zhejiang, Jiangsu, area, four, Shanghai, and four regional cultivation total amounts account for 79% of whole nation cultivation total amount.Current prawn feed waste is serious, feed return rate is low and body eutrophication outstanding problem, and cause unit aquaculture product to yield poorly, the culture-cycle is long, raiser's inefficiencies.China's prawn culturing area is still in expansion, and cultural technique still needs to improve.

Summary of the invention

In order to solve the problems of the technologies described above, the invention provides a kind of different according to prawn Different growth phases nutritional need, rationally protein level being set, meeting nutritional need, improve the prawn pellet of growth rate.

In order to achieve the above object, the prawn pellet that the present invention obtains, it is characterized in that comprising following composition by weight percentage: white fish meal 20%-25%, domestic fish meal 15%-20%, dregs of beans 15%-20%, peanut press pulp 10%-15%, flour 20%-25%, cuttlefish cream 2%-3.5%, shrimp shell meal 10%-15%, phosphatide oil 2%-2.5%, fish oil 2%-2.5% and calcium dihydrogen phosphate 1%-1.5%, salt 0.5%-0.8%, shell plain 0.4%-0.8%, Choline Chloride 0.2%-0.4%, compound micro-ecological preparation 0.1%, compound liver and gall preparation 0.1%, vitamin C 0.3%-0.5%, B B-complex 1.5% and composite mineral salt 2.0%, to produce in accordance with the following methods: raw material feeds intake → and coarse crushing → raw material cabin → batching → first time, mixing → ultramicro grinding → sieved → mixing → granulation → cooling → screening → packed products for the second time.Wherein said compound micro-ecological preparation by: oligosaccharide (glucose, manna oligosacchride and peptide glycan) and peptide class (glutathione, carnosine and antibacterial peptide), multiple Chinese herbal medicine (turmeric, hawthorn, Radix Glycyrrhizae and tea extract) form, strengthen prawn immunocompetence and anti-stress ability, build up health, growth promoting effects.

The prawn pellet that the present invention obtains, is suitable for the Penaeus Vannmei of the long 2.0-4.5cm of body, Macrobrachium rosenbergii, freshwater shrimp, raises together with shrimp crab etc.Different according to prawn Different growth phases nutritional need, rationally protein level is set, meets nutritional need, improve growth rate, effectively can reduce again protein resource waste, increase economic benefit.By improving starch burn degree, effective raising feed digestion absorptivity, there is the effect that significantly promotes production, prawn immunoglobulin level can be significantly improved, strengthen the activity of phagocyte and lysozyme, improve shrimp body to the resistance of pathogen, thus improve specification and the quality of finished product prawn, raiser's economic benefit is improved significantly.

Detailed description of the invention

Below by embodiment, the present invention will be further described.

Embodiment 1.

The prawn pellet that the present embodiment describes, it is characterized in that comprising following composition by weight percentage: white fish meal 20%-25%, domestic fish meal 15%-20%, dregs of beans 15%-20%, peanut press pulp 10%-15%, flour 20%-25%, cuttlefish cream 2%-3.5%, shrimp shell meal 10%-15%, phosphatide oil 2%-2.5%, fish oil 2%-2.5% and calcium dihydrogen phosphate 1%-1.5%, salt 0.5%-0.8%, shell plain 0.4%-0.8%, Choline Chloride 0.2%-0.4%, compound micro-ecological preparation 0.1%, compound liver and gall preparation 0.1%, vitamin C 0.3%-0.5%, B B-complex 1.5% and composite mineral salt 2.0%, to produce in accordance with the following methods: raw material feeds intake → and coarse crushing → raw material cabin → batching → first time, mixing → ultramicro grinding → sieved → mixing → granulation → cooling → screening → packed products for the second time.
