Problems solved by technology

[0003] There are many methods about the preparation technology of prawn feed. The prior art, such as the Chinese invention patent with the public number of CN 102106478 B, discloses a prawn feed. The prawn feed of the inventive method contains fish meal, soybean meal, peanut bran, rapeseed meal, brewer's yeast, flour, starch, corn oil, fish oil, K 2 HPO 4 1. Total psyllium flavonoids, the inventive method uses petroleum ether extraction in the step of preparing total psyllium flavonoids, which will cause residues of petroleum ether and thus cause potential harm to prawns, and soybean meal and rapeseed meal contain anti-nutritional ingredients, which will cause Shrimp has an adverse effect on the absorption of feed nutrients, and the main component of feed, fishmeal, is expensive, which increases the cost of feed

Embodiment 1

[0016] The preparation method of fortified feed for prawn breeding period comprises the following steps:

[0017] 1) Weigh 100 parts of soybean meal and 2 parts of molasses, add distilled water to control the water content to 40%, adjust the pH to 6.8, and the temperature to 23°C, inoculate with 2.0% of Bacillus licheniformis, 1.8% of yeast, and 2.0% of lactic acid bacteria, every 24 hours Turn the material once, ferment for 72 hours, and dehydrate at low temperature to obtain fermented soybean meal; after fermentation, the anti-nutritional factors in the soybean meal are decomposed and removed, rich in protein, organic matter, and medium and trace elements, suitable as the base material for prawn feed;

[0018] 2) Weigh 400 parts of a mixed solution of sodium dihydrogen phosphate and disodium hydrogen phosphate with a pH of 0.08mol / L and a pH of 7.3, slowly add 8.2 parts of tea polyphenols, heat to 55°C under vigorous stirring and keep at a constant temperature; weigh egg yolk...

Embodiment 2

[0021] The preparation method of fortified feed for prawn breeding period comprises the following steps:

[0022]1) Fermented soybean meal: Weigh 150 parts of soybean meal and 3 parts of molasses, add distilled water to control the water content to 50%, adjust the pH to 7.2, and the temperature to 28°C, inoculate with 2.5% of Bacillus licheniformis, 2.0% of yeast, and 2.2% of lactic acid bacteria, Turn over once every 36 hours, ferment for 96 hours, and dehydrate at low temperature to obtain fermented soybean meal; after microorganisms enter the shrimp body, they can change the microbial community composition of the shrimp intestine, improve the growth rate of the shrimp, enhance disease resistance, and improve immunity;

[0023] 2) Preparation of tea polyphenol liposomes: Weigh 450 parts of a mixed solution of 0.10 mol / L sodium dihydrogen phosphate and disodium hydrogen phosphate with a pH of 7.5, slowly add 8.5 parts of tea polyphenols, and heat to 58 ℃ and keep constant tem...

Embodiment 3

[0026] The preparation method of the enhanced feed for prawn breeding period includes: preparation and compounding of fermented soybean meal and tea polyphenol liposome, specifically including the following steps:

[0027] Fermented soybean meal: Weigh 120 parts of soybean meal and 3 parts of molasses, add distilled water to control the water content to 50%, adjust the pH to 7.0, and the temperature to 25°C, inoculate 2.5% of Bacillus licheniformis, 2.0% of yeast, and 2.0% of lactic acid bacteria. Turn over once every hour, ferment for 96 hours, and dehydrate at low temperature to obtain fermented soybean meal; after fermentation, the anti-nutritional factors in soybean meal are decomposed and removed, rich in protein, organic matter, and medium and trace elements, suitable as the base material for prawn feed; After the shrimp is in vivo, it can change the microbial community composition of the shrimp intestine, improve the growth rate of the shrimp, enhance the disease resista...

Abstract

The invention discloses a preparation method of fortifying feed for a prawn breeding season. The preparation method comprises the following steps: preparing fermented soybean meal and tea polyphenol liposome, and compounding. The preparation method has the beneficial effects that anti-nutritional factors in the fermented soybean meal are decomposed and removed; the fermented soybean meal is rich in protein, organic substances and medium trace elements, and is suitable to serve as a base material of prawn feed; microbial community composition of intestinal tracts of prawns can be changed aftermicrobes enter into the bodies of the prawns, so that the prawn growth speed is improved, the anti-disease capacity is enhanced and the immunity is improved; the feed is rich in nutrients, such as protein, amino acid, fat, vitamins and mineral element, is assisted by a phagostimulant, can meet the nutritional requirements of the growth and the development of parent prawns, promote the growth and the gonadal development of the prawns and prepare for the reproduction of the prawns, and is nutrition fortifying feed for the prawn breeding season, which is highly targeted and safe and does not havetoxic or side residues.

Description

technical field [0001] The invention belongs to the field of fortified feed for aquatic animals, in particular to a method for preparing fortified feed for prawn breeding period. technical background [0002] Prawns, the scientific name is Oriental prawns, also known as Chinese prawns, Chinese prawns, and spotted prawns. Arthropoda, Mollusca, Decapod, Shrimpidae, Penaeus. Prawns are large in size and are commonly known as prawns. The female growth of prawns generally has a body length of 16-22 cm and weighs about 50-80 grams. The largest can reach 30 cm and weighs 250 grams; the male is smaller, with a body length of 13-18 cm and a weight of 30-50 grams. Prawns are wide-temperature and wide-halt marine animals. The body of Penaeus mangniu Island is long cylindrical, flat on the left and right sides, and the body is divided into head, thorax and abdomen, and consists of 20 body segments. The abdomen is long, muscular and well segmented. Shrimp is rich in nutrition, and i...
