Abstract

The shift toward antibiotic-free (ABF) livestock farming has emphasized the need for effective strategies to enhance animal immunity and prevent disease outbreaks. Strengthening immune resilience through improved nutrition, biosecurity measures, and the use of natural immunomodulators is essential for maintaining animal health without relying on antibiotics. Probiotics, prebiotics, phytogenics, and vaccination programs have emerged as key approaches to supporting immune function and disease resistance in livestock. This paper explores various strategies for enhancing animal immunity, addressing challenges in ABF farming, and highlighting the role of sustainable management practices in ensuring productivity and animal welfare.
