The invention discloses a breeding method for intensively preventing and controlling goose gout and application of the breeding method, and aims to solve the technical problems of high incidence of goose gout and low survival rate in intensive goose breeding. According to the method, prevention and control are achieved through a cooperative scheme of graded disinfection, precise trace element supplement and environment regulation and control; 50-250 ppm hypochlorous acid is adopted for conducting graded sterilization on the goose house environment, a feeding trough and drinking water, and pathogen breeding and urate deposition inducements are cut off; when the geese are 15-75 days old, a German Q life water trace element solution is added into drinking water, the excretion function of the kidney is enhanced, and metabolic balance is adjusted; meanwhile, the breeding density is controlled to be 1-4 / m, the environment humidity is 55-70%, and ventilation and daily average activity amount are guaranteed. The method is accurate and safe in prevention and control and free of drug residues, the gout incidence rate of goose groups can be reduced to 4% or below, the survival rate is increased to 95% or above, the weight gain efficiency in the breeding period is increased by 10%-15%, the breeding cost and loss are remarkably reduced, the method is suitable for intensive breeding scenes of medium and small meat geese, breeding geese and the like, and comprehensive economic benefits are outstanding.

The application belongs to the technical field of food processing, and particularly discloses fish glue polypeptide, a preparation method and application thereof. The preparation method comprises three procedures of acid immersion pretreatment, repeated homogenization and gelatinization treatment and ultrasonic wave assisted immobilized enzyme degradation treatment. The fish glue polypeptide has an average molecular weight of 3.2-8.4 KDa, a molecular weight dispersion coefficient of 0.2-0.5, a small molecular weight, a concentrated molecular weight distribution, a good polypeptide activity, and is beneficial to promoting the absorption of trace elements when applied to fish glue polypeptide-trace element supplement products. When the concentration in the aqueous solution is 2 g / L, the Zeta potential of the micelle is-24 mV to-30 mV, the average particle size of the micelle is 10-20 nm, the particle size dispersion coefficient of the micelle is 0.1-0.2, the average particle size of the micelle is small, the particle size distribution of the micelle is concentrated, the Zeta potential of the micelle is high, and the micelle has good stability.

The invention relates to the technical field of composite materials, and discloses a copper-zinc chelated composite material, a preparation method thereof and an application of the copper-zinc chelated composite material in a feed. The preparation method comprises the following steps: modifying rice bran meal by adopting physical and chemical methods to obtain modified rice bran meal; further modifying the composition of the rice bran meal by adopting a biological enzymolysis method to obtain functionalized rice bran meal; reacting copper sulfate and zinc sulfate with glycine and calcium carbonate, ending the reaction when no bubbles are generated in the system, and centrifuging to obtain a copper ion solution and a zinc ion solution; and mixing the functionalized rice bran meal with a copper ion solution and a zinc ion solution, adding a lactic acid bacteria solution for fermentation, and after the reaction is finished, obtaining the efficient copper-zinc chelating composite material. The high-efficiency copper-zinc chelated composite material can be used as a trace element supplement in a feed.

The present invention relates to the technical field of functional beverages and discloses a herba epimedii and rhizoma polygonati beverage and a preparation method thereof, and the herba epimedii and rhizoma polygonati beverage comprises the following raw materials in parts: 5-10 parts of herba epimedii, 8-15 parts of rhizoma polygonati, 3-6 parts of Chinese wolfberry fruits, 5-8 parts of red dates, 4-7 parts of Chinese yams, a trace element supplement, 2-5 parts of white granulated sugar, 1-3 parts of honey, an additive and purified water. The herba epimedii, the rhizoma polygonati and trace elements such as zinc, selenium and manganese are compounded, the zinc element can promote absorption and conversion of icariin, the selenium element and rhizoma polygonati polysaccharide synergistically enhance the oxidation resistance, the problem that a traditional beverage is single in nutrition is solved, meanwhile, the retention rate of icariin in a finished product is high, the recovery rate of the trace elements is high, and the product quality is improved. By adopting a beta-cyclodextrin inclusion technology, the problem of precipitation of trace elements and plant polyphenols is solved, the stability of the beverage placed for a long time is improved, and by adding Chinese yam, fructo-oligosaccharide and the like, the content of dietary fibers is enriched, and the bitter taste of herba epimedii is neutralized.

The invention relates to the technical field of environmental microorganisms and fermentation engineering, in particular to a nitrifying bacteria consortium fermentation method based on microelement regulation and control. Culturing consortia formed by ammonia oxidizing bacteria AOB and nitrite oxidizing bacteria NOB into a fermentation seed solution; in the fermentation process, microelement supplementing liquid is added according to the oxygen consumption rate value, stage supplementing is conducted, a mixed fermentation system with AOB and NOB synchronously and stably increased is formed, the problems that nitrifying bacteria are unstable in fermentation and have no nitrite nitrogen degradation capacity are solved, the single-tank fermentation time is shortened, the production cost is reduced, and the production efficiency is improved. The ammoxidation rate of a finished product is improved.

This invention relates to the field of organic fertilizer and animal by-product resource utilization technology, and discloses a long-acting slow-release fertilizer stick based on animal hoof keratin. The fertilizer stick comprises the following components, by dry basis mass percentage (wt%): 80-98% animal hoof keratin powder; 0-15% organic binder; 0-15% inorganic slow-release regulating material; 0-15% nutrient enhancer; 0-3% trace element supplement; 0-5% plant-derived antibacterial component; and 1-15% soluble pore-forming agent. This long-acting slow-release fertilizer stick based on animal hoof keratin utilizes animal hoof shells as the main raw material, achieving high-value utilization of waste; simultaneously, it uses natural, biodegradable keratin as the slow-release matrix, avoiding the use of synthetic polymer coating materials, thus reducing the risk of microplastic pollution at the source. This is achieved by constructing a "dense on the outside, loose on the inside" gradient structure and a network of interconnected pores formed by the pore-forming agent.
