Embodiment 1

[0020] Utilize the method for preparing feed from shrimp leftovers, the concrete steps are as follows:

[0021] 1) Pretreatment: Wash prawn scraps with ice water for 3~4 times, remove sediment and some harmful bacteria, crush them initially, add water with a material-to-liquid ratio of 1:2~1:3, mix well, and crush with ultrasonic waves The instrument is crushed, the power is 60~100W, and the time is 10~30min. The free active zinc and some free amino acids are dissolved in the liquid, filtered, centrifuged to obtain the precipitate and supernatant, and the supernatant is freeze-dried. Concentrated powder of free active zinc and amino acids. Because active zinc and amino acids will be inactivated at high temperatures, they are concentrated and dried by freeze-drying;

[0022] 2) Activation: Mix the two strains according to the quantitative ratio of Lactobacillus bulgaricus and Bacillus subtilis at a ratio of 1:1~1:4, insert into the activation medium for activation, the activat...

Embodiment 2

[0031] Utilize the method for preparing feed from shrimp leftovers, the concrete steps are as follows:

[0032] 1) Pretreatment: Wash the shrimp scraps with ice water for 3 times to remove the sediment and some harmful bacteria, and then crush them initially, add water with a material-to-liquid ratio of 1:3, mix them evenly, and crush them with an ultrasonic crusher with a power of 80W, time is 20min, the free active zinc and some free amino acids are dissolved in the liquid, filtered, centrifuged to obtain the precipitate and supernatant, and the supernatant is freeze-dried to obtain the concentrated powder of free active zinc and amino acid. Because active zinc and amino acids will be inactivated at high temperatures, they are concentrated and dried by freeze-drying;

[0033] 2) Activation: Mix the two strains according to the quantitative ratio of Lactobacillus bulgaricus and Bacillus subtilis at a ratio of 1:2, insert into the activation medium for activation, the activati...

Abstract

The invention provides a method for preparing a fodder by utilizing shrimp leftovers. The method comprises the following steps: 1) preprocessing; 2) activating; 3) primarily fermenting; 4) preparing compound albumen powder; and 5) preparing the fodder. The method has the beneficial effects that the strong acid production capacity and enzyme production capacity of lactobacillus bulgaricus and bacillus subtilis are utilized to treat the shrimp leftovers under the assistance of additive 1; protein and calcium carbonate are removed from the shrimp shells; according to the method, the protein extraction rate is high and the decalcification rate of the shrimp shells is high; the bacillus subtilis is compounded into alpha-amylase and protease which can degrade the vegetable protein and decompose the vegetable protein inhibitors; the vegetable protein in bean pulp is decomposed into quickly absorbed and digested small molecular weight protein and amino acid, the protein category is enriched and the fodder nutrition is more complete; and the preparation method is simple in operation, high in protection extraction rate, high in activity of extracted protein and high in economic benefit.

Description

technical field [0001] The invention relates to the technical field of feed preparation, in particular to a method for preparing feed using shrimp leftovers. Background technique [0002] Prawns are mainly distributed in the Yellow Sea, Bohai Sea, Liaoning Lushun, Tianjin and the coastal areas of Shandong Province in my country. They are the main shrimp cultured in coastal cities. my country is a big country in shrimp trade, and shrimp occupies an important position in all fishery products, accounting for about 20% of the total value of international fishery trade. [0003] With the rapid development of the aquaculture industry, a small part of my country's prawns are used to cook dishes, and most of them are exported to all parts of the world. Most of the exported products are frozen shrimps, and the heads of the shrimps are discarded. Therefore, a large number of by-products such as shrimp shells and shrimp heads are produced during the production and processing of prawn...
