Embodiment 1

[0037] The method for preparing antibacterial nutritional compound feed additive from fresh tilapia leftovers comprises the following steps:

[0038] S1. Preparation of fermentation ingredients: mince fresh tilapia (visceral part) scraps, add soybean meal, bran and bagasse (passed through a sieve less than 60 mesh), and mix according to the mass ratio of 4:1:1:0.2 to obtain the base material, then add 1% molasses, 0.5% sodium glutamate, 0.05% dipotassium hydrogen phosphate, 0.1% MgSO 4 ·7H 2 0 and 60% water, the prepared material is packed into a rotary steamer, and steamed under a pressure of 0.2Mpa for 15min. When the material temperature drops to 40°C after steaming, the final moisture is kept at 70%.

[0039] S2. Solid fermentation: when the temperature of the material is 30°C, inoculate the expanded Bacillus natto seed liquid by 1% by mass, and mix evenly. The inoculated material is transported to a ventilated fermentation tank (bed) in a fermentation workshop with a t...

Embodiment 2

[0043] The method for preparing the antibacterial nutritional compound feed additive from the leftovers of fresh prawn shrimp head comprises the following steps:

[0044] S1. Preparation of fermentation ingredients: mince the head of fresh prawns, add soybean meal, bran and bagasse (less than 60 mesh), mix according to the mass ratio of 8:1:1:0.3, then add 4% molasses, 0.1% sodium glutamate, 0.05% dipotassium hydrogen phosphate, 0.1% MgSO 4 ·7H 2 0 and 65% water, the prepared material is packed into a rotary steamer, and steamed under a pressure of 0.2Mpa for 18min. When the temperature of the material drops to 40°C after steaming, the final moisture is kept at about 70%.

[0045] S2. Solid fermentation: when the temperature of the prepared fermentation material is at 35° C., inoculate 2% by mass of Bacillus natto seed liquid through enlarged cultivation, and mix evenly. The inoculated material is transported to a ventilated fermentation tank (bed) in a fermentation worksho...

Embodiment 3

[0049] The method for preparing the antibacterial nutritional compound feed additive from fresh scallop skirt scraps comprises the following steps:

[0050] S1. Preparation of fermentation ingredients: mince fresh scallop skirt, add rapeseed meal, bran and rice husk, mix according to the mass ratio of 5:1:1:0.2, and then add 2% molasses and 0.2% corn by weight of the base material Sodium Amino Acid, 0.06% Dipotassium Hydrogen Phosphate, 0.2% MgSO 4 ·7H 2 0 and 65% water, the prepared material is packed into a rotary steamer, and steamed under a pressure of 0.2Mpa for 20min. When the material temperature dropped to 40°C after steaming, the final moisture remained at 72%.

[0051] S2. Solid fermentation: when the temperature of the prepared fermentation material is at 35° C., inoculate 2% by mass of Bacillus natto seed liquid through enlarged cultivation, and mix evenly. The inoculated material was transported to the ventilated fermentation tank (bed) of the fermentation work...

Abstract

The invention belongs to the technical field of a feed additive, and discloses a method for producing a compound antibacterial nutrient feed additive by utilizing offal of aquatic products. The method comprises the following steps: using the offal of aquatic products as main raw materials, adding forage plant protein, bran and bagasse ( or rice husk) in an assistant manner, adding natto bacillus NT-6 bacterial strains for solid fermentation, and combining a secondary enzymolysis regulation and control technology, so that the prepared feed additive can be used as a substitute of forage antibiotics and other growth promoting agents so as to improve the production performance, the immunity, the disease resistance and the feed conversion rate of animals; the feed additive can also be used for preventing and treating multiple diseases in the breeding process of the animals. According to the method, the production technology of forage bioactive peptide can be simplified, the product cost can be notably reduced, the efficacies of products are improved, the using range of the products is extended, the added value of the offal is increased, the residue-free discharge and efficient environmental-friendly industrial production of the forage bioactive peptide can be realized, and the healthy sustainable development of breeding industry of the aquatic products is promoted.

Description

technical field [0001] The invention relates to the technical field of feed additives, and more specifically relates to a method for producing antibacterial nutrition compound feed additives by using leftovers of aquatic products. Background technique [0002] The amount of waste from aquatic product processing in my country is huge, the level of reuse is low, waste and environmental pollution are serious, and it is urgent to explore new methods of reprocessing with high added value and low emission. Feed active peptide is a high-value, low-threshold product, which has become a new way to develop and utilize low-value marine proteins. Antimicrobial peptides and nutritional small peptides, as the main members of feed active peptides, are considered to be the most potential substitutes for feed antibiotics. [0003] Bacillus antimicrobial lipopeptide is a class of antimicrobial peptide family, and its members usually include surfactin, fengycin, iturin, bacillomycin, anti-mol...
