Problems solved by technology

[0005] However, on the one hand, the above methods cannot fundamentally improve the intestinal environment of poultry, and on the other hand, there are many problems: 1. Due to the short intestinal tract of poultry, it is difficult for the additive components to fully exert their effectiveness when passing through the intestinal tract, resulting in poor effect 2. Extensive use of antibiotics not only destroys the ecological balance of normal flora in animals, reduces the immune function of animals, but also cannot avoid causing serious problems such as the development of drug resistance of pathogenic microorganisms and the harm caused by drug residues to humans and the environment.

Embodiment 1

[0025] The invention provides a feed additive for regulating intestinal functions of poultry, which comprises a microbial mixed bacterial agent and medicinal magnetite powder, wherein the mass ratio of the microbial mixed bacterial agent to the medicinal magnetite powder is 10:1.

[0026] Among them, the microbial mixed bacterial agent includes Bacillus licheniformis, Lactobacillus plantarum and Clostridium butyricum, and the mass ratio of the components of the microbial mixed bacterial agent is 2:3:1.

[0027] Its preparation method comprises the following steps,

[0028] S1 Fermentation and multiplication of each component strain of the microbial mixed bacterial agent, and drying to make powder;

[0029] S2 washing and drying the medicinal magnetite powder, sterilizing at low temperature, and then grinding and sieving;

[0030] S3 washing and drying the nano-montmorillonite powder, high-temperature sterilization, and then grinding;

[0031] S4 uniformly mix the products ob...

Embodiment 2

[0034] Replace medicinal magnetite powder with magnetic ultrafine particle MeFe 3 o 4 , keeping other conditions unchanged.

[0035] Among them, the magnetic ultrafine particle MeFe 3 o 4 The preparation method is that the low-carbon iron sheet is dissolved in sulfuric acid to obtain a divalent iron solution, and a-FeOOH suspension is obtained under the dual action of NaOH and oxygen, and an appropriate amount of manganese and zinc sulfate solution is added to the suspension. And adjust the pH value of the solution with NaOH to form co-precipitation, and then input it into the boiling reflux device and obtain it by forced hydrolysis for phase inversion.

Embodiment 3

[0037] Except that the conditions of Example 1 remain unchanged, it also includes nano-montmorillonite powder, and the mass ratio of nano-montmorillonite powder, microbial mixed bacterial agent and medicinal magnet is 10:5:1.

[0038] Bacillus licheniformis, Lactobacillus plantarum and Clostridium butyricum are all acid-resistant, anaerobic or facultative anaerobic bacteria, which can improve animal intestinal permeability, enhance intestinal immune function, prevent and reduce diarrhea in animals and other gastrointestinal diseases. As a biological substitute for antibiotics, it is often used in feed additives. Long-term feeding can avoid drug resistance and superinfection caused by antibiotics.

[0039] The nano-montmorillonite gel formed by mixing nano-montmorillonite powder and intestinal juice has a "carriage-like structure", which can fix the bacterial flora in the "carriage". The principle of its adsorption lies in the negative electric adsorption characteristics deter...

Abstract

The invention provides a feed additive for adjusting poultry intestinal functions and a preparation method of the feed additive. The feed additive comprises a microbial mixed inoculant and medicinal magnet powder, the mass ratio of the microbial mixed inoculant to the medicinal magnet powder is (1-10): 1, the microbial mixed inoculant comprises Bacillus licheniformis, Lactobacillus plantarum and Clostridium butyricum, and the feed additive further comprises nano montmorillonite powder; the microbial mixed inoculant, the nano montmorillonite powder and the medicinal magnet powder enter intestinal tracts of poultry along with a digestive system, the magnet powder forms a magnetic field with a certain field intensity, the microbial mixed inoculant and probiotics existing in the intestinal tracts are greatly promoted to exert efficacy, and the nano montmorillonite powder becomes a carrier of microbial community and the magnet powder to effectively improve the existence and efficacy time ofprofitable community in the intestinal tract, and meanwhile, common pathogenic bacteria and bile salt in the intestinal tract are adsorbed in the intestinal tract and discharged out of poultry bodiesalong with excrement, and the occurrence of diarrhea is reduced.

Description

technical field [0001] The invention relates to the technical field of feed addition, in particular to a feed additive for regulating intestinal function of poultry and a preparation method thereof. Background technique [0002] Poultry generally has a short intestinal tract, commonly known as "rectum", and its digestion and absorption capacity is weaker than that of mammals. When feeding ducks, they often pull out thin feces containing undigested feed due to indigestion. Adverse effects on poultry health. At the same time, poultry are prone to diarrhea due to infection of pathogenic bacteria in the intestinal tract or environmental stress, and even lead to mass death of poultry in severe cases. [0003] Investigating the reason, technicians found that because the intestines of poultry are generally short, the nutrients entering the intestines cannot be fully digested and absorbed, thereby destroying the normal physiological environment in the intestines, reducing the activ...
