摘要

Background

This review provides an overview of how antibiotic residues are found in the environment and affect livestock, thereby shedding light on the physiological mechanisms of their toxicity.

Objective

We aimed to emphasize the need for improved antibiotic management in agricultural practices to mitigate environmental contamination and reduce risks to livestock. Understanding the mechanisms by which antibiotic residues exert toxic effects is critical to the development of sustainable solutions.

Results

Antibiotic residues in the environment are a growing concern because of their widespread use in livestock farming and persistence in ecosystems. This review examines the pathways by which antibiotics enter soil, water, and sediments, primarily through manure application, wastewater discharge, and direct excretion by animals. Once in the environment, these residues affect soil quality, water systems, and animal health, posing risks, such as toxicity, disruption of microbial communities, and physiological harm to livestock. Persistent antibiotics, including fluoroquinolones and tetracyclines, accumulate in animal tissues and alter metabolism, leading to adverse effects, such as joint damage and impaired growth. In addition, these residues can degrade into toxic metabolites, further affecting livestock health and the environment.

Conclusion

Collectively, these findings suggest that future research may be required to prioritize strategies to mitigate environmental contamination by antibiotics and explore alternatives to reduce exposure in livestock production.
