IMPACT OF AGRICULTURAL PLANT HORMONE ON ANIMAL HEALTH: A CRITICAL REVIEW OF EVIDENCE AND IMPLICATIONS

Abstract

The widespread use of plant hormones in modern agriculture, such as auxins, cytokinins, gibberellins, and synthetic growth regulators, has significantly enhanced crop yield and quality. However, the potential un-intended consequences of these agrochemicals on animal health remain poorly understood. This critical review synthesizes current evidence on the environmental persistence, bioaccumulation, and physiological effects of agricultural plant hormones on domestic and wild animals. Emerging studies suggest that exposure—either through contaminated feed, water, or indirect ecological pathways—can disrupt endocrine functions, reproductive health, and metabolic processes in livestock and wildlife. The review highlights key knowledge gaps, such as species-specific responses and long-term exposure outcomes, and underscores the need for comprehensive toxicological assessments and regulatory frameworks. Addressing these concerns is essential to safeguarding animal welfare, food safety, and ecological integrity in hormonally modified agricultural systems.
