* Specific Cedar Species: While most cedar species are safe, some varieties like Eastern Red Cedar (Juniperus virginiana) contain thujone, a volatile oil that can be toxic in high doses.
* Ingestion Amount: Even with safe cedar species, overconsumption can lead to digestive upset.
* Individual Sensitivity: Some cows may be more sensitive to certain plant compounds than others.
Symptoms of Cedar Toxicity:
* Abortion: This is rare, but possible in extreme cases of thujone exposure.
* Digestive Issues: Diarrhea, vomiting, and decreased appetite.
* Nervous System Issues: Tremors, seizures, and disorientation.
Recommendations:
* Provide alternative forage: Ensure your pregnant cows have access to plenty of nutritious and palatable grasses, legumes, and hay.
* Monitor for unusual behavior: If you observe any of the symptoms listed above, contact your veterinarian immediately.
* Consult a veterinarian: If you have concerns about your pregnant cows' access to cedar trees, or any other potential toxins, it's best to speak with a veterinarian.
In general, it's best to limit the access of pregnant beef cows to cedar trees, especially Eastern Red Cedar, and focus on providing them with safe and nutritious food sources.
