Abstract: As a novel experimental animal, the alpaca demonstrates significant application value in the biomedical field due to its unique immune characteristics and physiological structure. Alpaca-derived nanobodies, which offer advantages such as small size, high stability, and low immunogenicity, have been widely applied in disease diagnosis and treatment as well as food safety testing; the physiological characteristics of alpacas make them suitable for the construction of various medical models; their involvement in animal-assisted intervention provides new avenues for mental health interventions; strains and antimicrobial peptides isolated from alpaca intestines or feces offer resources for the development of alternatives to antibiotics and medical materials. This review summarizes the research progress of experimental alpacas in medical applications, providing a theoretical basis for the transformation of alpacas into standardized medical resources.
