Other plants are known to bring about weight loss, weakness and a reduction in performance. Keeping a keen eye on horses and checking for any signs of distress daily will help you to identify problems before they become life threatening.
How to Prevent Poisoning
Once you know what is poisonous to horses, thoroughly check your horse pasture and paddock area for any harmful plants and trees. Be sure to check both sides of the fence line and identify all plants growing within reach. If you spot anything suspicious, do not allow your horses to graze in the area until you have removed the plant or tree. Young or ambitious horses, especially, need to be watched very carefully.
You should also know where your hay comes from. Many toxic plants can be found in hay that is dried and this too can be very dangerous. Don’t be afraid to ask questions from your hay supplier to bring you peace of mind when feeding your horses. Do not allow horses to overgraze pastures and never turn a hungry horse out into a new pasture.
Always provide plenty of fresh water for horses and be sure to consult your veterinarian immediately if you suspect that your horse has ingested a toxic plant. Horses and poisonous plants are not a good combination and taking the time to study which plants and trees are toxic and managing your pasture properly could be a matter of life and death.
