However, there are some factors to consider:
* Limited information: There is limited research on the effects of lambs ears on livestock, and the potential for toxicity may vary depending on the species and individual animal.
* Potential for digestive upset: While not poisonous, consuming large quantities of lambs ears could cause digestive upset in some animals due to its fuzzy leaves and potentially high fiber content.
* Allergic reactions: Some animals might have allergic reactions to lambs ears, though this is uncommon.
Overall, it's best to be cautious and not allow livestock to graze heavily on lambs ears. It's always a good idea to consult with a veterinarian or an agricultural expert for specific advice on the safety of particular plants for your livestock.
