From Antibiotic Replacement to Efficient Immune Enhancement-Yeast Cell Wall

introduction

      In recent years, with the increasing awareness of food safety and environmental protection, the aquaculture industry has faced severe challenges such as antibiotic resistance and drug residue caused by antibiotic abuse. How to achieve green farming without sacrificing animal health and production performance? Yeast cell wall - a multifunctional component derived from natural yeast, is becoming a new favorite in the field of animal nutrition due to its unique effects such as enhancing immunity, regulating the intestine, and adsorbing toxins. This article combines scientific research and practical applications to reveal how yeast cell walls can open a new chapter of health for modern aquaculture.

1、 Yeast cell wall: the "hard core" effect of natural ingredients

      Yeast cell wall is a natural product extracted from brewing yeast through acid hydrolysis, enzymatic hydrolysis and other processes. Its main components are β - glucan and oligosaccharides (MOS), supplemented by glycoproteins and chitin. These components endow their three core functions:

      Immune enhancement: β - glucan can activate immune cells such as macrophages and T cells, enhance non-specific immunity in animals, and reduce the occurrence of diseases.

      Intestinal regulation: Mannan oligosaccharides competitively adsorb pathogenic bacteria, promote the proliferation of beneficial bacteria (such as lactobacilli), maintain intestinal microbiota balance, and reduce diarrhea rates.

      Toxic adsorption: Its spiral structure can specifically bind to mycotoxins such as aflatoxin and zearalenone, reducing the threat of toxins to animal and food safety.

2、 Scientific Verification: Successful Practice from Laboratory to Ranch

      Case 1: Double improvement of milk production and dairy quality in cows

      Adding 50 grams/day of yeast cell wall to the diet of dairy cows resulted in an average increase of 14.85% in milk production after 55 days, an increase in milk protein content from 3.1% to 3.3%, and a significant increase in milk fat percentage. The mechanism is that yeast polysaccharides promote rumen microbial protein synthesis and improve intestinal immune function.

Case 2: Effective management of calf health

      Research has shown that adding 75mg/kg yeast glucan to the diet of calves can reduce the frequency of diarrhea, significantly reduce the number of Escherichia coli in feces, and reduce the incidence of respiratory diseases from 9.9% to 3%.

Case 3: Enhancing Disease Resistance in Aquaculture

      Adding yeast cell wall polysaccharides to aquatic feed can enhance the lysozyme activity and antiviral ability of fish and shrimp. For example, feeding Indian white shrimp with feed containing 0.2% glucan significantly increased the survival rate of white spot virus (WSSV).

3、 The "Four Advantages" of Green Aquaculture

      Safe and residue free: The yeast cell wall is a natural extract with no risk of drug residue, which complies with the EU anti drug policy and China's green food standards.

      Alternative antibiotics: By enhancing immunity and inhibiting pathogens, reducing antibiotic dependence in aquaculture, and assisting in the transformation of "antibiotic free farming".

      Significant economic benefits: improving feed conversion rate, reducing mortality rate, and increasing product added value (such as milk protein content) while reducing overall costs.

      Environmentally friendly: Reduce the pollution of soil and water caused by antibiotic emissions, and promote sustainable development.

4、 Future prospects: From ruminants to full industry chain applications

      At present, yeast cell walls have been widely used in dairy cows, beef cattle, aquaculture and other fields, and research is extending to poultry, pigs and other animals. With the in-depth study of the molecular mechanisms of functional polysaccharides, their application scenarios will be further expanded:

      Customized additives: Develop specific ratio products for different animal needs;

      Joint efficiency enhancement: synergistically used with probiotics, plant essential oils, etc. to create a comprehensive health plan;

      Toxic prevention and control: Against the backdrop of increased risk of mold growth in feed raw materials, it has become the preferred ingredient for fungal toxin adsorbents.

conclusion

      The rise of yeast cell walls is not only a technological advancement, but also a microcosm of the transformation of aquaculture towards green and efficient practices. It uses scientific data to prove that health and benefits can be achieved simultaneously. For ranchers and feed companies, seizing this trend may be the key to winning the future market!
