Problems solved by technology

[0005] The purpose of the present invention is to provide a fermented soft pellet feed for Penaeus vannamei and its preparation method and application, mainly to solve the problem of moldy and direct production of fermented wet feed during storage. If the water content of the grain is too high, it will not resist extrusion, and it will dissolve too quickly when put into water.

Embodiment 1

[0046] Embodiment 1, a kind of fermented soft pellet feed for Penaeus vannamei

[0047] A kind of fermented soft granular feed for Penaeus vannamei is provided in this embodiment, see figure 1 , the soft pellet feed comprises the following raw materials in parts by weight:

[0048] Aspergillus niger solid fermentation compound enzyme 40kg / ton;

[0049] Bacillus coagulans powder 1kg / ton;

[0050] Fermentation wet material 500kg / ton;

[0051]Adhesive 15kg / ton;

[0052] High-gluten flour 434kg / ton.

Embodiment 2

[0053] Embodiment 2, a kind of preparation method of fermented soft pellet feed for Penaeus vannamei

[0054] 1. Comparative study on the ratio of different raw materials and the fermentation effect of different lactic acid bacteria

[0055] In the experiment, the inoculation amount of lactic acid bacteria was 10 6 CFU / g raw material, water content is 40%, sealed anaerobic fermentation for 48h. The decrease in pH after fermentation represents the acid production during lactic acid fermentation. The results show that: using different lactic acid bacteria to ferment formula 4, Pediococcus lactis has the strongest pH-lowering ability, see figure 2 ;according to image 3 with Figure 4 The results show that increasing the amount of corn flour in the formula is beneficial to the reduction of pH, but when the amount of corn flour added reaches 50%, the content of lactic acid bacteria after fermentation is significantly lower than when the amount of corn flour added is less; add...

Embodiment 3

[0081] Embodiment 3, the application of a fermented soft granular feed in feeding Penaeus vannamei

[0082] The commercially available Penaeus vannamei was purchased on June 11, 2018, and has been temporarily raised to a body length of 5-6cm and a weight of 4-5g / tail. In the aquarium circulating water system (aquarium length 39cm × width 39cm × height 33cm, effective water body 50L, Figure 12 ) for breeding experiments, the water temperature is (27±2)℃, the salinity is 24‰, the electromagnetic air pump is used to continuously inflate, and the Zhongke DC frequency conversion water pump is used for circulation, the flow rate is 12000L / H, the whole system has 32 aquarium tanks, and a cycle is completed in 3 hours . The experiment selected (4.6±0.08)g 144 prawns and divided them into two groups: Group A was fed with 100% commercially available 1.0mm prawn pellets, and group B was fed with the mass ratio of commercially available 1.0mm prawn pellets to fermented soft pellets. Fe...

Abstract

The invention provides fermented soft pellet feed for Pacific white shrimp and a preparation method and application thereof. The feed is prepared from the components: 40-50 kg / ton of solid fermentation complex enzyme of Aspergillus niger, 1-1.5 kg / ton of bacillus coagulans powder, 400-600kg / ton of fermented wet feed, 10-20kg / ton of a binder and 400-450kg / ton of high-gluten flour. According to thesoft pellet feed, low temperature pelletizing is performed on lactic acid bacteria and yeast fermentation broth-fermented wet feet and the solid fermentation complex enzyme and the bacillus coagulanspowder, and soft pellets which can be directly ingested by shrimps can be made through the action of the binder; the combination of the lactic acid bacteria and yeast suppresses the mildewing of the soft pellets; and the feed is mainly used in the culture of Pacific white shrimp, and is of great significance for improving production performance, reducing food coefficient, and improving the water environment of culture.

Description

technical field [0001] The invention belongs to the technical field of biological feed for aquaculture, and in particular relates to a fermented soft granular feed for Penaeus vannamei and its preparation method and application. Background technique [0002] Penaeus vannamei is one of the highest-yielding shrimp species. In 2018, the total national aquaculture output was 1.76 million tons, accounting for 43% of all crustacean aquaculture output. Acute hepatopancreatic necrosis syndrome and intestinal diseases are the main diseases in the culture of Penaeus vannamei, and the mortality rate is extremely high once the disease occurs due to the lack of specific immunity. In daily management, the application of biological agents and disinfectants is mainly used to improve the water environment and reduce the incidence of disease. The frequency of use of biological feed and microecological preparations in shrimp farming is very high, and the main dosage forms include powder, liqu...
