Introduction
The poultry industry is rapidly moving toward antibiotic-free and sustainable production systems. Feed manufacturers must deliver solutions that maintain bird performance, strengthen immunity, and protect gut health without relying on antibiotic growth promoters.
Beta MOS is one such proven solution. It is a synergistic combination of Beta-Glucans and Mannan Oligosaccharides (MOS) derived from yeast cell walls. By combining gut-cleaning action (MOS) with boosting immunity (Beta-Glucans), Beta MOS delivers consistent performance benefits across broilers, layers, and breeders.
This article explains what Beta MOS is, how it works, its benefits, applications, and supporting clinical evidence, helping feed companies confidently position Beta MOS in modern poultry feed programs.
What Is Beta MOS?
Beta MOS is a functional feed ingredient that combines:
- Mannan Oligosaccharides (MOS) – prebiotics that bind harmful pathogens and improve gut hygiene.
- Beta-1,3/1,6-Glucans – bioactive polysaccharides that stimulate and train the immune system.
Both components originate from the cell wall of Saccharomyces cerevisiae and work together to support gut health, immunity, and nutrient utilisation.
Unlike antibiotics, Beta MOS does not kill bacteria. Instead, it supports the birds’ natural defence and digestive systems, making it ideal for antibiotic-free poultry production.
Mode of Action of Beta MOS
Beta MOS works through two complementary mechanisms: gut protection and immune activation.
1. Pathogen Binding and Removal (MOS Action)
Many harmful bacteria, such as E. coli, Salmonella, and Clostridium, attach to the intestinal lining using mannose-specific receptors.
MOS prevents pathogens from attaching to the intestinal lining and facilitates their removal from the digestive tract.
Result:
- Reduced pathogen colonisation
- Lower gut inflammation
- Improved intestinal hygiene
2. Support of Beneficial Gut Microflora
MOS selectively promotes beneficial bacteria like Lactobacillus and Bifidobacterium. These microbes:
- Produce short-chain fatty acids (SCFAs)
- Improve gut pH
- Strengthen the intestinal barrier
Result: Better digestion and nutrient absorption.
3. Immune Activation and Training (Beta-Glucan Action)
Beta-Glucans bind to immune receptors on macrophages and heterophils in the gut. This interaction:
- Activates innate immunity
- Improves phagocytic activity
- Enhances immune readiness
Instead of overstimulating the immune system, Beta-Glucans train immune cells to respond faster and more effectively during disease challenges.
4. Improved Gut Integrity
Clinical studies show that Beta MOS improves:
- Villus height
- Villus-to-crypt ratio
- Goblet cell count and mucin secretion
Result: A stronger gut barrier with better nutrient uptake and lower pathogen penetration.
Key Benefits of Beta MOS in Poultry
1. Improved Growth Performance
Beta MOS improves:
- Body weight gain
- Feed conversion ratio (FCR)
- Flock uniformity
Several trials report performance equal to or better than antibiotic growth promoters, especially under field conditions.
2. Better Gut Health
By combining MOS and Beta-Glucan, Beta MOS:
- Reduces harmful bacteria
- Stabilises gut microflora
- Improves gut structure
A healthier gut leads directly to better productivity.
3. Stronger Immunity
Beta MOS enhances:
- Macrophage activity
- Antibody production
- Vaccine response
Birds become more resilient to infections and stress.
4. Lower Mortality and Better Survival
Improved gut health and immune readiness help reduce disease pressure and mortality, especially during:
- Early life
- Heat stress
- Disease outbreaks
5. Supports Antibiotic-Free Production
Beta MOS is widely used in:
- Antibiotic-Free (ABF) programs
- No Antibiotics Ever (NAE) systems
It helps producers maintain performance while meeting regulatory and consumer demands.
Clinical Evidence Supporting Beta MOS
As Beta MOS contains MOS and Beta-Glucan, its benefits are supported by extensive research on both components.
1. Growth Performance and Gut Health
- Large-scale broiler trials show MOS improves body weight gain and FCR while reducing intestinal pathogen load.
- Studies demonstrate improved villus height and gut morphology, leading to better nutrient absorption.
2. Immune Function and Disease Resistance
- Beta-Glucan supplementation increases macrophage activity, antibody titers, and immune gene expression.
- Birds show stronger immune responses during coccidiosis, bacterial, and viral challenges.
3. Synergistic Effects of MOS + Beta-Glucan
- Teng et al. 2021 (Poultry Science) demonstrated that the combination of MOS and Beta-Glucan improved:
- Body weight gain
- Jejunal villus height
- Immune gene expression
This confirms the synergy behind Beta MOS, where gut protection and immune activation work together.
Applications of Beta MOS in Poultry Feed
Broilers
- Starter: early gut development and immune priming
- Grower–Finisher: improved FCR and uniformity
Layers
- Improved gut health
- Stable egg production
- Better immune status
Breeders
- Improved reproductive performance
- Better chick quality
Stress Conditions
- Heat stress
- Vaccination
- Disease challenges
Why Feed Companies Should Choose Beta MOS?
- Dual action: gut health + immunity
- Backed by clinical research
- Easy to formulate
- Supports antibiotic-free claims
- Strong differentiation in the market
Beta MOS allows feed manufacturers to offer complete gut immunity solutions, not just single-function additives.

FAQs
1. What makes Beta MOS different from regular MOS or Beta-Glucan?
Beta MOS combines two proven yeast components – MOS and Beta-Glucan in one formulation. MOS improves gut hygiene by binding harmful pathogens, while Beta-Glucan trains the immune system. This dual action delivers stronger and more consistent results than using either ingredient alone.
2. Can Beta MOS replace antibiotic growth promoters in poultry feed?
Yes. Multiple studies show that Beta MOS delivers comparable improvements in growth performance, feed efficiency, and bird health to antibiotic growth promoters, making it an effective solution for antibiotic-free and NAE programs.
3. At what stage should Beta MOS be used in poultry diets?
Beta MOS can be used throughout the production cycle:
- Starter phase for gut development and immune priming
- Grower–finisher for better FCR and uniformity
- Layers and breeders for gut health, immunity, and productivity
Early inclusion delivers the strongest long-term benefits.
4. Does Beta MOS work under field and stress conditions?
Yes. Beta MOS has proven effective under commercial field conditions, including:
- Heat stress
- Disease challenge
- Vaccination stress
- High microbial load environments
Its immune-training and gut-protective effects help birds maintain performance under pressure.
5. Is Beta MOS safe and compatible with other feed additives?
Beta MOS is safe, natural, and non-antibiotic. It is compatible with:
- Probiotics
- Organic acids
- Enzymes
- Phytogenics
It integrates easily into existing feed formulations without affecting feed stability.
6. What are the key performance indicators feed companies can expect from Beta MOS?
Feed companies and producers typically observe:
- Improved body weight gain
- Better feed conversion ratio (FCR)
- Healthier gut morphology
- Stronger immune response
