Biotics as Sustainable Alternatives to Antibiotics in Nigerian Poultry Farming

Abstract

Poultry production is a crucial sector in Nigeria, contributing significantly to the economy, food security, and livelihoods of millions. However, productivity remains challenged by disease outbreaks, antibiotic resistance, and inefficient feed conversion. With growing restrictions on antibiotic use and increasing consumer demand for antibiotic-free poultry products, probiotics, prebiotics, and postbiotics are emerging as sustainable alternatives. These biotic additives play a key role in improving gut health, digestion, immunity, and overall poultry performance. Probiotics are live, beneficial microorganisms that help maintain gut microbial balance and prevent harmful pathogens from colonizing the intestines. Prebiotics are specific non-digestible feed components that promote beneficial gut bacteria growth and metabolic activity, enhancing nutrient absorption. Postbiotics, the metabolic byproducts of probiotics, provide additional immunomodulatory and antimicrobial benefits without the viability concerns of live probiotics. Together, these biotics contribute to better feed conversion, improved disease resistance, and greater sustainability in poultry production. This paper reviews the latest developments in probiotics, prebiotics, and postbiotics in Nigerian poultry farming, examining their mechanisms of action, effectiveness, and practical applications. It also explores emerging trends such as precision nutrition and innovative delivery technologies while addressing challenges related to adoption, regulation, and cost-effectiveness. Integrating these biotic strategies into poultry feeding programs can enhance productivity, reduce antibiotic reliance, and promote long-term sustainability in Nigeria’s poultry industry.
