Abstract:

This article provides a review of the impacts and potential ecological risks of antibiotics and resistance genes in livestock and poultry farming environments. Through systematic research on the relevant literature, the use of antibiotics in livestock and poultry farming in different regions was summarized. The study found that the residual concentrations of antibiotics and resistance genes in soil after returning livestock and poultry manure to the field varied due to factors such as manure type, region, farm scale, and management measures. Moreover, the migration and transformation of antibiotics and resistance genes in soil are influenced by the soil type and fertilization methods. This study specifically explored the impact of the spreading of resistance genes through mechanisms such as horizontal gene diffusion by soil microorganisms and systematically elucidated the ecological risks of antibiotics and resistance genes. Finally, based on the current pollution situation of returning livestock manure to the field, a summary and outlook on reducing the accumulation and diffusion of antibiotics and resistance genes in the environment were prepared. The work is expected to provide strong support for a comprehensive understanding of the environmental impacts and ecological risks of antibiotics and resistance genes in livestock and poultry farming.

Key words: antibiotic, antibiotic resistance gene, livestock manure, ecological risk
