Summary

Veterinary clinicians must consider environmental toxins like biotoxins, nitrates, and certain plants when diagnosing infertility and abortions in food animals. Regional knowledge is crucial for identifying specific toxic exposures impacting animal reproduction.

Area of Science:

  • Veterinary Toxicology
  • Animal Reproduction

Background:

  • A significant number of toxins negatively impact food animal reproduction.
  • Clinicians must be aware of these toxins and their mechanisms of action.

Purpose of the Study:

  • To highlight the importance of considering toxins in cases of food animal reproductive failure.
  • To provide a framework for clinicians investigating infertility, abortions, and congenital defects.

Main Methods:

  • Review of known reproductive toxicants affecting food animals.
  • Emphasis on regional considerations for plant- and mineral-based toxins.
  • Integration of toxicological assessment within broader differential diagnoses.

Main Results:

  • Common reproductive toxicants include biotoxins, plant estrogens, nitrates, fescue toxicosis, and selenium accumulation.

  • Teratogenic plants are a key consideration for congenital defects.
  • Geographic location influences the prevalence of specific toxins.

    • Conclusions:

    • Toxicological evaluation is essential for diagnosing reproductive issues in food animals.
    • Differential diagnoses must include infectious and management factors alongside toxins.
    • Understanding regional toxicological risks improves diagnostic accuracy.
