Abstract

The growing concerns over antibiotic resistance and its implications for both animal and human health have sparked interest in alternative strategies for promoting animal health in livestock and poultry farming. One promising alternative is the use of probiotics as feed additives, which offer a sustainable solution to replace or reduce the reliance on antibiotics. Probiotics, live microorganisms that confer health benefits to the host when administered in adequate amounts, play a vital role in enhancing gut health, improving nutrient digestion, and boosting the immune system of animals. This paper explores the potential of probiotics as a safe and effective substitute for antibiotics in animal feed. It reviews the mechanisms by which probiotics can modulate the gut microbiome, prevent pathogenic infections, and enhance the overall health and productivity of livestock. Additionally, the paper discusses the environmental benefits of probiotic use, including reduced antibiotic resistance risks, minimized pollution from antibiotic residues, and improved sustainability in animal agriculture. While challenges such as regulatory hurdles and the need for further research in certain species remain, the integration of probiotics into animal nutrition represents a promising strategy for sustainable and health-conscious farming practices. This paper highlights current findings, practical applications, and future directions for the use of probiotics in animal feed as part of a broader movement toward antibiotic-free and environmentally friendly animal husbandry.
