Prebiotics, Postbiotics, and Lignocellulose in Animal Nutrition

Optimizing gut health is essential for animal performance and welfare. Natural solutions such as prebiotics, postbiotics, and lignocellulose fibers play a vital role in promoting microbiome balance, improving digestion, and reducing reliance on antibiotics.

Prebiotics: Fuel for Beneficial Microbes

Prebiotics are non-digestible fibers that selectively stimulate the growth of beneficial gut bacteria. They enhance nutrient absorption, improve gut integrity, and support immune function. Common sources include inulin, oligosaccharides, and plant-derived fibers.

Postbiotics: Bioactive Compounds for Health

Postbiotics are metabolic byproducts of probiotics, including short-chain fatty acids, peptides, and enzymes. These compounds strengthen gut barrier function, reduce inflammation, and improve overall animal health without introducing live microorganisms.

Lignocellulose: Natural Fiber for Gut Health

Lignocellulose, derived from plant cell walls, provides insoluble fiber that regulates gut motility and prevents digestive disorders. It supports microbiome diversity and enhances feed efficiency, making it a sustainable component of animal diets.

One Health Perspective

Integrating prebiotics, postbiotics, and lignocellulose into animal nutrition reduces antibiotic dependence, lowers antimicrobial resistance risks, and promotes food safety. This approach benefits animal health, human health, and environmental sustainability, aligning with the One Health concept.

Non-Antibiotic Growth Promoters and Nutraceuticals

Non-Antibiotic Growth Promoters (Non-AGPs) are feed additives designed to enhance animal growth and health without relying on antibiotics. They include probiotics, prebiotics, enzymes, and plant extracts that improve gut integrity, nutrient absorption, and immunity.

Nutraceuticals are bioactive compounds derived from natural sources that provide health benefits beyond basic nutrition. They support immune function, reduce oxidative stress, and promote overall performance in livestock.

Both Non-AGPs and nutraceuticals contribute to sustainable livestock production, reduce antimicrobial resistance risks, and align with the One Health approach for animal, human, and environmental well-being.
