With the global demand for poultry on the rise, ensuring the delivery of safe and high-quality products has become increasingly crucial. Strengthening the gut barrier offers a proactive and sustainable approach to mitigating foodborne risks while protecting both poultry and human health.
Poultry is a staple in diets worldwide, featuring in everything from chicken stir-fries to Sunday roasts. In 2023, global poultry meat consumption reached an unprecedented 140 million tonnes, alongside an impressive 91 million metric tonnes of egg production. These figures underscore the vital role poultry plays in global nutrition.
However, with increasing demand comes greater responsibility. Foodborne pathogens such as Salmonella and Campylobacter pose significant risks to public health and the poultry industry. They are the primary causes of foodborne illness, resulting in symptoms such as diarrhea and fever. The economic implications are staggering, with estimated costs in the European Union alone reaching €2.4 billion and €3 billion annually for infections from Campylobacter and Salmonella, respectively.
To ensure consumer safety and maintain sustainable poultry production, innovative strategies are essential—strategies that focus on enhancing gut health at the core.
Understanding the Gut Barrier
When considering disease prevention in poultry, measures like biosecurity, vaccinations, and improved food processing often come to mind. Yet, one of the most effective defenses resides inside the birds themselves: in their gastrointestinal tract and its microbiota.
The gut serves not only as a digestive organ but also as a barrier that absorbs nutrients, houses immune cells, and facilitates competition between beneficial and harmful bacteria. A healthy gut contributes to disease resistance, optimal performance, and reduced pathogen transmission to humans.
Maintaining a balanced and diverse microbiota is crucial. Beneficial microbes in the gut enhance nutrient absorption and immune response while inhibiting the growth of harmful pathogens. However, this balance can be easily disrupted by stress, poor diet, or illness.
Harnessing the Power of Mannan-Rich Fraction (MRF)
Alltech’s proprietary mannan-rich fraction (MRF), derived from Saccharomyces cerevisiae, provides poultry producers with a valuable tool for enhancing gut health, boosting microbiota diversity, and lowering pathogen levels.
MRF operates on multiple levels. It encourages a more diverse and stable gut microbiota, demonstrated through studies on both broilers and layers. MRF supplementation has been shown to enhance α-diversity and β-diversity, indicating a healthier microbiome. A diverse microbial community helps birds better resist harmful organisms.
Furthermore, MRF effectively lowers harmful bacterial loads. Research shows significant reductions in E. coli, Clostridioides difficile, and other key pathogens, meaning fewer harmful bacteria are present in birds, which translates to improved safety during processing and reduced risk to consumers.
Blocking Pathogen Colonization
MRF also binds directly to pathogens, preventing them from attaching to the gut lining. Many harmful bacteria, including Salmonella, utilize fimbriae to adhere to gut receptors. MRF mimics these receptors, leading pathogens to bind to it instead of the gut wall, hindering their ability to multiply and cause harm. The bound bacteria are subsequently expelled naturally.
This mechanism is particularly critical for managing Salmonella, known for its diverse strains and rapid evolution. MRF has demonstrated effectiveness against various Salmonella isolates, significantly reducing prevalence in laying hen tissues—an essential step in mitigating eggshell contamination.
Addressing Antimicrobial Resistance (AMR)
Food safety encompasses not only disease prevention but also the preservation of antibiotic efficacy. Antimicrobial resistance (AMR) presents a significant threat to global health, with millions of deaths annually directly linked to drug-resistant infections.
AMR arises when bacteria adapt to withstand treatments that previously eradicated them. Over 50% of Salmonella found on poultry carcasses has shown moderate to high resistance to common antibiotics, thus making AMR a pressing food safety concern.
While many countries have banned the use of antibiotics as growth enhancers, withdrawal alone hasn’t fully addressed the problem, as resistant bacteria can persist in the gut and environment, spreading their resistance. Here, MRF shines once again. Alltech’s research indicates that MRF not only binds pathogens but also enhances their susceptibility to antibiotics, enabling more effective treatments and reducing resistant populations.
A Comprehensive Strategy for Poultry Health
Solving pathogen issues in poultry production requires a multifaceted approach that integrates robust biosecurity, effective vaccinations, hygienic processing, and consumer education. At the heart of this strategy is a focus on gut health, which lays the groundwork for disease resistance, improved performance, and safer food.
Alltech’s MRF technology provides scientifically backed solutions by promoting microbial diversity, inhibiting harmful pathogens, and addressing AMR. It offers poultry producers a natural and effective means to fortify the gut barrier in their flocks.
Ensuring Safety from Within
As the global demand for poultry escalates, the imperative to provide safe, premium products intensifies. Strengthening the gut barrier presents a proactive method for minimizing foodborne risks, thus safeguarding both poultry and the communities that depend on them for nourishment.
Incorporating gut health technologies such as MRF into poultry management not only aligns with scientific advancements but serves as a practical approach in the ongoing fight against pathogens and AMR. When the gut is fortified, the benefits ripple across the entire food supply chain.
